The Bureau of Reclamation awarded the Boise Project Board of Control a $7,260,000 Project Grant under the WaterSMART (Sustain and Manage America's Resources for Tomorrow) program (CFDA 15.507) to replace 5,230 linear feet (1 mile) of canal lining on the New York Canal in Boise, Idaho. This project aims to increase water conservation, efficiency, and reliability by reducing seepage losses from the existing concrete and asphalt-lined canal.

The key activities include removing the existing flooring, compacting fill material, and installing a geocomposite membrane canal liner secured with concrete and rebar. The project is expected to minimize post-installation seepage, allowing 4,047 acre-feet of water per year to remain in the reservoir system for irrigation, landscaping, and hydropower generation. This initiative will also benefit local ecosystems and recreational activities by conserving this precious water resource, especially during periods of drought.

Activities

NYC lining phase 10: from station 175 00 to station 228 00 the cross-sectional width of the new york canal is approximately 60 feet wide. The existing flooring is concrete that transitions into unlined, earthen flooring. The north and south walls of the canal consist of a mix of concrete and or asphalt. The asphalt and concrete on the flooring will be removed along with two feet of dirt. One foot of fill material will be compacted into the floor and sides. The geocomposite membrane canal liner will be installed and laterally seamed every 25 feet and adhered together with a specialized adhesive made especially by the makers of the lining. Six inches of concrete with ranch panels on the sides and 4 rebar on the flooring is then layered on top of the membrane.expected deliverables or outcomes: post-project seepage losses are expected to be minimal. After installation seepage will be minimal allowing for the 4,047 acre-feet per year will remain in the reservoir system until IT is to be used for its intended purpose, irrigation of crops and landscaping, with the ability to generate power. According to the study performed by the bureau of reclamation and their report titled intended beneficiaries: with the water in the canals and not seeped into the ground, bpbc is able to deliver irrigation water to users and generate 4 kilowatts of power with the two low-hydro power plants and less water needs to be diverted into the new york canal and allows this precious commodity to stay in the reservoirs longer which will benefit the production of power through arrowrock powerplant and the water will be stored for future use especially if the drought continues as forecasted by NOAA and contribute to the survival of the threatened bull trout, along with the other species of fish in the reservoirs.subrecipient activities (if known or specified at time of award): n a
