The North Platte River – Multiuse water

Part 3 – The Kendrick Project – Seminoe and Alcova

By Gary Stone, Nebraska Extension Water & Integrated Cropping Systems Educator

This will be a six-part series on the dams, reservoirs, power generation and some diversion dams located on the North Platte River. The series will follow a chronological order of the history and construction of these projects.

The first dam and reservoir on the North Platte River after it enters from Colorado is Seminoe. Seminoe dam is part of the Kendrick Project intended to generate hydropower and expand irrigation in central Wyoming. The project, called the Casper-Alcova Project, was authorized in 1933 under the National Recovery Act during the Great Depression. The project was renamed the Kendrick Project in 1937. The Kendrick Project also includes the Alcova dam, reservoir, and the Casper-Alcova Canal.

Seminoe dam is located about seventy-five miles southwest of Casper, Wyo. Construction started in 1934 and was completed in 1938. This dam was constructed expressly for the purpose of hydropower generation. The dam is a medium-thick concrete arch 295 feet high with a crest length 530 feet. The reservoir capacity is 1,017,280 acre-feet and provides water for approximately 24,265 acres for the Kendrick Project. The power plant has three generators that can produce 13,500 kilowatts each.



Alcova dam is located about 30 miles southwest of Casper, Wyo., the fourth dam on the North Platte River. Construction started in 1935 and was completed in 1938. The dam is a zoned earthfill structure 265 feet high. The reservoir has a capacity of 184,405 acre-feet. The power plant was added in 1955. There are two generators which can produce 18,000 kilowatts each.

The Civilian Conservation Corps built roads, and other facilities for recreational purposes around Alcova reservoir. Camping, fishing, and boating are major uses of the reservoir along with irrigation and hydro power generation.



The Casper-Alcova Canal was completed in 1935. It takes water from Alcova reservoir to irrigate the land under the Kendrick Project around Casper. The canal is 59 miles long, has six concrete lined tunnels and a capacity of 1,200 cubic feet per second.

Both Seminoe and Alcova reservoirs help with flood control by managing the flows of the North Platte River during wetter years and store water for drier years.

Still the question from my Water Law 101 series, what is water worth?
