Description:
Abstract:
Because of the well known problems of the river, the West Branch was identified as a restoration implementation site to be funded as part of the Federal Emergency Management Agency (FEMA) Project Impact Initiative. The Lamoille County Planning Commission (LCPC) coordinated the project development and construction of the river restoration project on the West Branch in Stowe, Vermont between 2000 and 2001. This is Phase I of the project. There is significant amount of work planned for both the West Branch and the main stem of the Little River.
The West Branch is a classic example of degraded river system due to multiple human disturbances. Occurring excessively in the 1980’s, gravel mining was just one of these disturbances. This reduction of sediment over-widened the stream channel, disallowing sufficient sediment transport. As of 2003, the West Branch (5.8 miles) is listed on the Environmental Protection Agency’s (EPA) 303(d) impaired waters list for the pollution listing of physical habitat changes.
There are several causes of instability on the West Branch, including excessive gravel mining, urban runoff, and floodplain encroachments. All of these have led to the West Branch’s active stream channel losing connection to its floodplain in many locations. The stream has responded to these human induced disturbances by trying to reestablish a new floodplain at a lower elevation and degrading its bed. The bed degradation has migrated upstream (head cut) and created additional instability. The head cut has also caused the adjoining tributaries to become unstable, further contributing to the excess sedimentation of the West Branch. During this valley forming process, additional stream energy has remained in the channel causing streambanks to oversteepen and the additional bank erosion has lead to a channel bed build up of sediment (aggradation). This sedimentation process has many adverse impacts on fisheries habitat and water quality. Deep pool areas have filled in with sediment and fish spawning habitat has become smothered with fine sediment.
Creating quality trout habitat in the West Branch was one of the restoration goals of the project. By re-establishing a stable reach of the river and providing habitat for all life stages of trout, the project partners hoped to achieve increases of instream cover and greater depth in pools.
Multiple site visits occurred during year 2002 (Spring and Fall), which was the first year following construction. In order to assess changes to the project area over a period of time, permanent photographic stations were established along the river. These photo stations are documented by Michael S. Adams of the Army Corps of Engineers on the site plans. Pre-restoration photos were taken by Mr. Adams prior to construction in 2001. These photos, titled 'Army Corps of Engineers Pre-Restoration Photo Inventory (2001) of the West Branch in Stowe, VT' can be found zipped with this dataset. The first year of photos were taken on September 27, 2002 and the second year photos were taken on September 8, 2003. These restoration photos are included in the 'Photo inventory of the Post-Monitoring (2002-2003) of the West Branch in Stowe, Vermont' zipped with this dataset. Data results for the 2003 post monitoring project are published in the spatial dataset titled 'Post Monitoring (2003) of the West Branch Natural Channel Design Restoration Project in Stowe, Vermont' (see Cross Reference for this metadata citation and information about data download).
NOTE that this metadata was generated using the NBII Biological Profile and includes information about methods in Section 2 that will be lost if imported into a metadata software that doesn't recognize the biological fields (i.e. ArcCatalog).
Purpose:
The purpose of the project was to implement streambank and fisheries habitat restoration by stabilizing eroding riverbanks, restoring floodplain access, and creating a geomorphologically stable channel, which may in turn have a positive effect on the sedimentation problems farther downstream, including the Waterbury Reservoir. This metadata documents aspects of the project implementation in 2001 and first year post-monitoring of this project in 2002. By conducting the post-construction monitoring (2002, 2003, and 2004), we will document the changes occurring in the stream and determine the success of Phase I of this project in order to assess the success of the fairly new bioengineering techniques used in this project. The Army Corps of Engineers has designated the West Branch under their Section 206 Habitat Restoration Projects.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Data meets current VGIS Surface Water Data Standards in its partial implementation. Attribute information for each restoration site was acquired by GPS data collection. Attributes have been quality checked by the person responsible for the data collection-and found to accurately represent the features on the ground.
Logical_Consistency_Report:
Points, nodes, lines, and areas conform to topological rules. Lines intersect only at nodes, and all nodes anchor the ends of lines. Lines do not overshoot or undershoot other lines where they are supposed to meet. There are no duplicate lines. Lines bound areas and lines identify the areas to the left and right of the lines. Gaps and overlaps among areas do not exist. All areas close. Network lines exist within all two dimensional ""2d"" features to ensure ""hydrologic connectivity"" from headwater reaches to receiving waters through the network of single line ""1d"", and ""2d"" rivers and lakes. ""Dummy"" lines separate polygonal rivers from lakes and exist nowhere else.
Completeness_Report:
This data layer is based on the best available surface water data across the state and has been enhanced via on-screen digitizing with the aid of photo-interpreting RF 5,000 scale orthophotos, derived contours and multi-spectral aerial photographs. It has not been subject to field checking. River and lakeshore features are seasonal and have been interpreted at the feature's position as of the date of the source photos. The best available surface water data sources include layers from VCGI, Regional Planning Commissions, Town GIS offices, USGS DLG, Regional projects (i.e., NFLRI, VBP etc.) and more. Standardized delineation methodologies were followed throughout the compilation of this data providing a high degree of consistency. All sections were taken as sections of lines, or the right or left banks of two arcs.
""""CERTIFIED"""" NHD DATA: Transport reaches are defined on nearly all features of type: stream/river, canal/ditch, artificial path, pipeline, and connector. Water body reaches are defined on the subset of lake/pond features identified as water bodies. Geographic names, where present, were carried over from both 1:24k DLG hydrography data and from the best available source data. Near the international boundaries with Canada, only the parts of features within the United States are delineated. Detailed capture conditions are provided for every feature type in the Standards for NHD (USGS, 1999), available online through <http://mapping.usgs.gov/standards/>.>
This dataset does not claim to include all potential or conducted river restoration sites in Lamoille County, VT.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Compiled to meet 4.92 meters horizontal accuracy at 95% confidence level. Tested (value varies by sub basin-see below) meters horizontal accuracy at 95% confidence level.
These values do not account for the error of the source digital orthophotos (approx. +/- 6 meters) on which the data is based. Horizontal accuracy was assessed by comparing 20 well defined """"check"""" points of the source RF 5,000 scale digital orthophotos against derived surface water data. This approach is detailed in the FGDC Geospatial Positioning Accuracy Standards (<http://www.fgdc.gov/standards/status/sub1_3.html>). Digitized data was overlaid upon the RF 5k scale digital orthophotos. Check points were assessed on-screen to determine the spatial difference between the delineated vector data features and the location of the features on the orthophotos. Check points are any combination of the following features: 1) Confluences of one dimensional streams (""""1d"""" or single line streams); 2) Confluences of two dimensional streams (""""2d"""" or double line streams represented as polygons); 3) Polygonal lake and pond features; and 4) Distinct island features. Personnel other than the originator conducted accuracy analysis. Data is believed to be of uniform positional accuracy. Potential errors were deemed to be random, thus check points were dispersed across the extent of the data.
Additional enhancement to data accuracy involved the use of RF 40,000 scale 1992-93 NAPP color infrared aerial photos (Lamoille and White River Sub basins only). The RF 5,000 scale surface water data was plotted at RF 20,000 scale and overlaid onto enlargements (RF 20,000 scale) of the photos to determine errors of omission of water polygons. Errors noted on Mylar were digitized on-screen using digital orthophotos.
River restoration sites were GPS'd using Trimble Pathfinder Basic Plus. Points were verified using benchmarks and found to be within 2 meters of accuracy.
Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Value: 4.92
Horizontal_Positional_Accuracy_Explanation:
Assessment of horizontal accuracy was conducted by following guidelines outlined in ""FGDC Geospatial Positioning Accuracy Standards Part 3: National Standards for Spatial Data Accuracy"", section 3.2.2 Accuracy Test Guidelines (<http://www.fgdc.gov/standards/status/sub1_3.html>). Accuracy checking is ideally conducted by a third party using an independent data source of higher accuracy than that used to create the data being tested.
The accuracies reported were generated under the following conditions:
1) Personnel other than the original editor conducted accuracy analysis,
2) The best ""independent source of higher accuracy"" available is the RF 5000 scale Vermont Mapping Program digital orthophotos on which the original editing is based, and
3) Potential errors were deemed to be random, thus test points were dispersed across the entire extent of the data.
OVERVIEW - Twenty random ""check"" points were generated along the finalized surface water drainage network and compared against their actual ""test"" points on the ground that were visible using the RF 5,000 scale digital orthophotos.
Horizontal accuracy was assessed by conducting the following steps in ArcView® for each sub basin:
1) The finalized surface water data was assessed to ensure that a single route represented the entire 8 digit cataloging unit (sub basin). If one didn't exist then it was created.
2) Using the ArcView® extension ""randpts.avx"", a user extension created by Jeff Jenness, a Wildlife Biologist and GIS Analyst with the US Forest Service at the Rocky Mountain Research Station in Flagstaff, AZ, 20 random points were generated as ""check"" points. This extension is available from the ESRI Arc Scripts website.
3) The ""check"" points and surface water data were overlaid upon the RF 5000 scale digital orthophotos to assess ""check""points with their true locations, i.e., ""test"" points. Test point locations were stored in a separate point theme. A ""key"" field was maintained between these data sets. In some locations it was not possible to determine a ""test"" point with a high level of confidence so the ""check"" point was moved to the closest location along the same linear feature where a ""test"" location could be adequately determined on the orthophoto. Check points included any combination of the following features: A) Confluences of one dimensional streams ""1d"" or single line streams); B) Confluences of two dimensional streams (""2d"" or double line streams represented as polygons); C) Polygonal lake and pond features; and D) Distinct island features.
4) Using the ArcView® sample script ""addxycoo.ave"", X,Y coordinates were added to the features tables of both the ""check and ""test"" point attribute tables. These were then exported to comma delimited text files.
5) Using an Excel spreadsheet, created by the Minnesota Planning Land Management Information Center in a publication titled the ""Positional Accuracy Handbook: Using the National Standard for Spatial Data Accuracy to measure and report geographic data quality "" (<http://www.mnplan.state.mn.us/press/accurate.html>), the delimited files were imported. This spreadsheet contains all formulas necessary to generate the NSSDA statistic representing average horizontal positional accuracy.
Source data for each sub basin is a composite of surface water data from different sources created using varying methodologies by numerous entities. Therefore, reported accuracy values are reported for this composite data. Features in this data are believed to be of uniform positional accuracy. Accuracy value does not take into account the horizontal positional accuracy of the source digital orthophotos, on which the data is based.

Methodology_Description:
STRUCTURAL ASSESSMENT: Below is a list of installed practices in 2001 and the 2002 performance evaluation. Several assessments of the condition and performance of the structures occurred during the monitoring year.
Stations are measured on the ground in feet from the beginning of the restoration section upstream to the end of the restoration section. For example, station 24+00 equates to 2400 feet from the beginning of the section. Station 28+50 equates to 2850 feet from the beginning of the restoration section. NOTE, however, that the measurement units are in meters for the spatial dataset. Photographs were taken of the eight stations and can be found zipped with the spatial dataset located at the spatial download site (see Metadata Section 6 - Distribution).
a. A grade control structure was installed at Station 7+00, consisting of a rock vane with two root wads. This structure is appropriately prohibiting upstream headcutting.
b. Double tree revetments were installed from Station 12+96-17+00. Tree revetments were not installed from 11+50-12+96 because the 'J' vane was not installed; therefore the downstream section was riprapped. The revetments have stabilized the bank from the first vane (~Station 13+70) to Station 17+00. The section of revetments below the first vane was blown out, which is discussed in a later section.
c. Two rock vanes were installed at Stations 13+00 and 13+70. The third 'J' vane was not installed, but instead the bank was riprapped. The vane was not installed because the blue-silt was not an adequate foundation for the vane. These vanes were designed to slow velocities along the bank by directing flows to the center of the waterway. The first vane initially served this purpose until the structure failed following the first storm event, which in turn blew out the tree revetments below it. It should be noted that one of the rocks in the vein moved out of place and flows cut through the vane moving closer to the bank. At first the damage was not too severe, but due to conflicts with the landowner (detailed in repair/maintenance section), repair work did not occur until November. Because of the time frame between the initial bank erosion and the actual repair, a significant extra amount of erosion occurred over the summer/early fall. The specifics of the failure have not been identified, but further discussion among project partners will occur during the winter of 2002/2003.
d. The two rock weirs at Stations 21+75 and 23+50 were not installed because the blue-silt sediments did not provide an adequate foundation.
e. A riffle-pool sequence from Stations 20+26-30+50 was established by raising the channel bed elevation by 1’-2’. A plan for relocation, creation of floodplain access and the placement of riprap along 500 linear feet of the right bank from Stations 24+00-29+00 was also established. A point bar was constructed on the left bank extending a maximum of 25’ beyond the existing OHW. This work created a geomorphologically stable channel with floodplain access and provides energy dissipation at bankfull discharges.
RIPARIAN VEGETATION:
The Lamoille County Natural Resources Conservation District (LCNRCD) coordinated the ordering of the vegetative plantings and was responsible for the completion of the spring plantings. The goal of the planted riparian area was to provide bank stability, in turn decreasing erosion. The area would also provide food and shade for aquatic life and wildlife. The area would also capture sediment and nutrients from surface water runoff. The riparian plantings were conducted in the spring of 2002 by Jim Smith; a stream restoration contractor with significant experience in riparian plantings. A variation of large trees and small trees and shrubs were planted at the site. The large trees were supplied by the Gary Drinkwater Nursery in Hardwick, Vermont. He supplied us with trees ranging from 11-15’ in height and 1-2 "" caliper. The large trees consisted of: red maple, sugar maple, white ash, white birch and gray birch. The small trees consisted of: swamp white oak, red oak, silver maple, red maple, sugar maple, white ash, black cherry, silky dogwood, highbush cranberry, and serviceberry. Each tree and shrub had a burlap brush blanket in order to keep weed growth down around the base of the plantings. The large trees also had a plastic tree guard surrounding their trunk in order to discourage girdling. The most visible trees directly next to the recreation path had a wire tree guard, which was more inconspicuous than the white plastic tree guards. A total of 100 large trees and 200 small trees and shrubs were planted in the spring of 2002. The project team also spent the spring of 2002 installing willow wattles for bank stabilization and trees and shrubs for riparian buffers. Both Stream-Co and native willows were used on the West Branch site for a total of 1000 feet. All plantings were completed by the first week of June 2002. The final as-planted site plan (zipped with the spatial dataset) shows the placement of the fall 2001 and spring 2002 vegetative plantings.
The project site was assessed on September 27, 2002, in order to assess the health and survival of the planted stock and document any suggested changes.
Upstream section, Stations 24+00 to 28+50: There was 100% survival of the large trees and approximately 90% survival of the small trees and shrubs. The trees and shrubs were free of any disease or insect infestation. There was also no evidence of wildlife damage to the plantings. The plantings appeared to be stable and hardy. The willows also were in excellent health.
Downstream section, Stations 12+00 to 17+00: There was 100% survival of the large trees and approximately 90% survival of the small trees and shrubs. The trees and shrubs were free of any disease or insect infestation. There was also no evidence of wildlife damage to the plantings. The plantings appeared to be stable and hardy. The willows also were in excellent health.
During the fall of 2001, tree revetments, willow wattles and brush blankets were installed from the harvest of dormant willows. The following are notes taken by Chris Smith/Eric Derleth from November 2001 site inspections:
275 ft. of willow wattles (est. area 275 sq.ft. = 31 sq. yd) 400 ft. of tree revetments 180 ft. x 2 ft. of willow stakes = 360 sq. ft. = 40 sq. yd 95 ft. x 20 ft. of willow stakes = 1900 sq. ft. = 211 sq. yd 25 ft. x 8 ft. of willow brush mat = 200 sq. ft. = 22 sq. yd.
Tree revetments: revetment trees appeared correctly installed (no gaps and tight to the bank) with duckbills and 3/16 inch cable. Height of upper row appeared to be at or near bankfull elevation. Revetments were constructed of either single or double rows of trees.
Willow wattles: wattles found to be correctly installed.
Willow stakes: Live stakes were found to be installed at a spacing of 3-4 feet, not the 2-3 feet that Peter stated he was shooting for. Depths of stakes ranged from 6 inches to over a foot. It is expected that live stakes that are less than a foot will undergo significant mortality next summer especially if it is dry.
All of the vegetation planted during the fall of 2001 also appeared to be in excellent health, with the exception of a few patches where willows did not bud.
REPAIR/MAINTENANCE: Following two big storm events, one in April 2002 (15th - 19th) and the other on June 17th, an assessment was conducted to see how the structures held up following high water events. The most upstream section of the restoration site has held up well through all the elements. In the downstream section just below the first rock vane, the tree revetments that had been installed in the fall of 2001 had completely blown out and some severe bank erosion had occurred. Plans were made to repair this section during the summer, although we ran into some landowner problems. As part of both the Army Corps of Engineers permit and the USFWS Partners for Fish and Wildlife agreement, the adjacent landowner, Paul Percy had agreed to move his fence back 25 feet from the top of bank. Mr. Percy only moved the fence 10-15 feet in most places. It was decided among project partners to not put any more money or work into the project until the measured buffer was fenced off. The fence was finally moved one week prior to the October 1st cutoff date for in-stream construction. This cut-off date is based on a recommendation by the State fisheries biologist in order to protect trout spawning. There were several discussions between the Army Corps of Engineers, State of Vermont River Morphologists and Fisheries Biologists and the District in trying to complete the repair work in the fall 2002, in order to avoid any further erosion that may be caused by the next spring’s high waters. An amendment to the original Army Corps of Engineers permit was issued and construction was performed on November 6 and 7, 2002.
FISHERIES: The most upstream section of the project site consists dominantly of riffle habitat. The right bank is riprapped with smaller rock, not providing superior cover. The willows on the lower terrace will eventually shade this side of the stream. The trees and shrubs on the higher terrace will also be beneficial as they grow, providing shade, stability and a beneficial food source. In the grade control structure at Station 24+00, the rocks are creating some deeper pockets within this straight riffle section. In the downstream section, the first vane has created a back pool in the angle between the vane and bank. This provides a deeper, slower area directly adjacent to the riffle created by the vane. As the vegetation grows in this section, it will provide the river with shade, decrease sediment loads and a good source of food matter.
The Vermont Department of Fish and Wildlife performed some fish (game fish-trout) surveys during the fall of 2002. Although preliminary data was not available, the following sites were surveyed using electrofishing methods.
SITE ELEVATION SECTION LENGTH Barnes Camp 1550' 263' Stowe Mt. Resort access 1440' 295' Stowe Mt. Resort snowmaking pond 1410' 250' Above Peterson Brook 840' 500' Bike Path near Trapps 750' 730' Percy's above Weeks Hill 544 700'

RECOMMENDATIONS: The project team will be meeting during the winter 02/03 in order to discuss the structural integrity and complexities of the site.
The upstream section of the West Branch restoration has performed extremely well through its first year. At this time, there are no recommendations for structural or vegetation changes.
The riparian vegetation has established itself extremely well. It is recommended that trees be planted, during the spring of 2003, within the remaining buffer on the downstream portion of Paul Percy’s land. This will complete plantings within the whole riparian buffer. In the spring of 2002, plantings were only placed in the 10-15’ section that had been fenced off. The final fenced off riparian area of 25’ will then be fully planted.
The bank section below the first rock vane, which was repaired in the fall of 2002, will be planted with willows in the spring of 2003, in order to stabilize the highly erodible bank.

Methodology_Description:
The engineering firm Dubois and King performed a hydraulic analysis on the West Branch using the 2000 version of the U.S. Army Corps of Engineers HEC-RAS hydraulic model. They utilized the most appropriate existing hydrology (peak rates of discharge) developed by others (Flood Insurance Studies, previous engineering reports, etc.). Flood discharges for the bank full event (Q1.5), 5 year, 10 year, 25 year, 50 year, and 100 year events were obtained and utilized.
Cross sections were developed from the 3-dimensional ground survey and were linked to the river stationing indicated on the base map. The cross sections along with other appropriate data (roughness coefficients, expansion and contraction losses, etc) were coded into the HEC-RAS and an existing condition hydraulic model was developed. The model computes appropriate hydraulic information such as water surface profiles, channel velocities, shear values along the edge of a bank, critical depth locations, hydraulic jumps, and other appropriate information necessary for the use in design of the river stabilization improvements.
The hydraulic engineer observed and documented the sediment transport capacity of the channel. Using the average channel velocities, the critical velocity to induce bed material transport and the fall velocity of the average pebble size in the channel, Dubois and King made an assessment of the sediment transport capacity of the channel.
Following the approval of improvements, Dubois and King prepared the engineering plans (site plans and site details) for the restoration construction in August of 2000. Modifications were submitted and approved by the Army Corps of Engineers in October, 2002. The As-Built and As-Planted engineering plans were prepared by the U.S. Department of Agriculture, Natural Resources Conservation Service. Some of these plans have been zipped with and served with this dataset. For additional information about the engineering plans, contact the Lamoille County Natural Resources Conservation District.

Overview_Description:
Entity_and_Attribute_Overview:
""""CERTIFIED"""" NHD DATA: The VHD, as part of the NHD is a """"core framework"""" dataset, is a comprehensive set of digital spatial data that encodes information about naturally occurring and constructed bodies of water, paths through which water flows, and related entities. The information encoded about features includes classification by type, other characteristics, a unique common identifier, the feature length or area, and (rarely) the elevation of the surface of water pools and a description of the stage of the elevation. For reaches, encoded information includes a reach code, the date the reach code was assigned, a unique common identifier, the reach length or area, and, for transport reaches, the stream level. Geographic names, and their identifiers in the Geographic Names Information System, are assigned to reaches or, if no reach is available, to features. The data also contain relations among reaches that encode the direction of water flow, metadata, and information that supports the exchange of future updates and improvements to the data.
Attributes are present that were not developed as part of the NHD dataset and standard, and that are not part of any standards. Note the Attribute Definition Source to identify source agencies.
Entity_and_Attribute_Detail_Citation:
""""CERTIFIED"""" NHD DATA: Ultimately, the VHD will only contain NHD compliant attributes.
