Projects

An understanding of the natural environment greatly enhances ATR's ability to collaborate on the goals of the project, work with the project leaders and provide a better final product. While partnering with the US Forest Service (USFS), US Fish and Wildlife Service (USFWS), Natural Resource Conservation Service (NRCS), Ducks Unlimited, land trusts, private consultants and individuals, ATR has improved habitat and waterways in a variety of ecosystems.

Rivers and Streams

NORTH FORK OF THE SALMON RIVER, ID

Project Owner: Idaho Department of Fish and Game

Details: At our work location, the North Fork of the Salmon River has a drainage area of 211 square miles. The bank full width is 35 feet and the valley slope is 1.5%. Base flow is approximately 40cfs and the average yearly peak is 380cfs.

Project Details:

The goal of the projects was to develop more pool habitat and cover for spawning salmon. The reach had been worked on several years earlier and there were several log weirs spanning the channel in various stages of degradation. We installed three new cross channel log weirs and repaired 3 existing weirs. We installed 9 engineered log jam structures to provide cover and encourage scour pool development. Two log/boulder hybrid weirs were installed and two boulder weirs were installed.

FAYLE REACH LEMHI RIVER, LEADORE ID

Project Owner: Lemhi Regional Land Trust
Project Details: The Lemhi River is a low gradient channel in east central Idaho. Base flows run from 70 cfs to 200 cfs depending on irrigation diversions. Channel widths where we worked were 50 to 120 feet. Project Details: The objective of the project was to reduce channel width. Channel widths were reduced from 50 to 120 feet to 25 to 30 feet. This was accomplished by constructing new channel and filling in existing channel. Where the existing channel was narrowed we constructed 3,650 linear feet of new banks. We installed fabric lifts along all the new banks to stabilize them while they revegetate.
IMA DOT SALMON, ELLIS, ID

Project Owner: Intermountain Aquatics /Idaho Department of Transportation
Project Details: The project goals were to stabilize about 300 lnft of bank along the Salmon River adjacent to highway 93. Rock and log toe revetment was placed to harden the toe of the slope. The vertical bank was sloped back. Vegetated soil lifts were installed up to OHW elevation and the site was prepped for revegetation using salvaged topsoil

IMA EAST CANYON CREEK, PARK CITY, UT

Project Details: The project stabilized 1,570 linear feet of eroding bank using vegetated soil lifts.

CASCADE COLUMBIA SILVER SIDE CHANNEL

Project Owner: Cascade Columbia Fisheries Enhancement Group
River Details: Silver side channel is an abandoned channel on the Methow River. Spring water feeds it most of the season and flood water in the spring. The existing condition was a slough 60’ to 120’ wide and one to 3 feet deep.
Project Details: 2,500 cyds of material was imported into the slough to construct a meandering “E” channel to provide juvenile salmon rearing habitat. The channel dimensions increased over the half mile project to accommodate the increasing ground water contribution. This was a highly sinuous channel with large amounts of woody debris added for cover. The project was constructed using the GPS system on the primary excavator.

Ponds and Wetlands

ROSGEN WOODS CREEK DRIGGS, ID

River Details: Woods Creek is primarily driven by spring flow. It is affected to some degree by spring runoff and irrigation return. The channel widths vary from 8 to 20.

Project Details: The project goals were to increase bank stability and sediment transport as well as spawning and fish ability. The channel was an incised E channel. We elevated the bed elevation and widened the channel to transition into a C type channel. We built up riffles using imported rock we screened from a pond project on the same site. We installed over 30 log and rock drop structures. We transplanted dozens of willows. We installed over 100 logs with root wads for cover and as log toe bank stabilization. The pond excavation removed 23,000 cyds. 18,000 cyds were screened to provide 5,000 cyds of gravel for the stream work.

TNC KILPATRICK POND, PICABO, ID

Project Owner: The Nature Conservancy

Project Details: The project goals were to reduce water temperature as Silver Creek runs through the Kilpatrick Pond. We used rock to construct stable bank through the center of the pond for 1,100 lnft reducing the width and area of open water by two thirds. The site was challenging to work in with 3 to 6 feet of mud and ground water entering the site. Great care was taken to avoid discharge into the flowing water of silver creek. Discharge water from the dewatering pumps was spread over uplands to settle and eventually return to the channel below the work area. A site adjacent to the pond was used as a barrow site to produce the fill required to bring the former pond up to the specified elevations to create a wetland.
