Little Cottonwood Brown Ditch Company, Brown Ditch Rehabilitation Project
Reclamation Funding: $1,000,000 Total Project Cost: $2,526,300

The Little Cottonwood Brown Ditch Company, near Salt Lake City, Utah, will improve the Little
Cottonwood Brown Ditch System by replacing the existing diversion dam with two radial gates. The
project will also replace 4.1 miles of open ditch and pipe with 2.7 miles of high density polyethylene pipe.
The project is expected to save 2,020 acre-feet of water per year currently lost to spills. The conserved
water will decrease the demand on the local groundwater resources and will be made available to meet
existing demands.

Mapleton Irrigation District and Company, Hobble Creek Ditch Piping Project
Reclamation Funding: $300,000 Total Project Cost: $1,220,000
The Mapleton Irrigation District and Company, located near Provo, Utah, will replace 3 miles of existing
open canals and a box culvert in Hobble Creek Canyon with a pressurized pipeline that will eliminate water
losses due to seepage, evaporation, and ditch failure. The project is expected to result in annual water
savings of 1,685 acre-feet which will be made available to existing users.

Peoa South Bench Canal and Irrigation Company, South Bench Piping and Small Hydro Project
Reclamation Funding: $1,000,000 Total Project Cost: $2,145,730

The Peoa South Bench Canal and Irrigation Company, near Salt Lake City, Utah, will replace the entire
South Bench canal system with 19,760 feet of enclosed, pressurized pipe that is more efficient and has a
less impactful alignment. The project also includes installation of a concrete screening structure, system
meter, and 100-watt micro-hydropower unit. The project is expected to conserve 2,629 acre-feet of water
annually that is currently lost to seepage, which will be made available to existing users. The hydropower
unit is expected to generate approximately 588 kilowatt-hours of power each year, which will serve local
canal operation power needs.

Provo River Water Users Association, Weber-Provo Diversion Metering Project
Reclamation Funding: $154,156 Total Project Cost: $308,312

The Provo River Water Users Association will add a piped bypass from the Weber-Provo diversion dam to
the Weber River to allow for year-round control of flows in the river. Currently, during the winter, the
diversion gate is frozen in place causing water to spill. The project also includes the installation of two
magnetic meters housed in concrete vaults to provide accurate, real-time measurement of flows in the
Upper Weber River. The project is expected to save 2,571 acre-feet of water per year by reducing spills
and reducing over-deliveries, which will be made available to existing users and will help ensure that water
rights, contracts, and instream flow needs are met.

Weber Basin Water Conservancy District, Woods Cross Small Secondary Water Metering and
Hydro Project
Reclamation Funding: $300,000 Total Project Cost: $750,000

The Weber Basin Water Conservancy District, near Salt Lake City, Utah, will install 750 meters on
residential landscape watering connections, providing real-time water usage data and outreach to
customers. The project is expected to result in water savings of 300 acre-feet per year, which will reduce
groundwater pumping and help meet future demands. The project also includes installation of a two-
kilowatt hydropower unit, expected to generate approximately 8.7 megawatt-hours of power, annually
which will be used to help meet the energy demands of the District.
