Paddock Valley Dam is a dam in Washington County, Idaho.
This earthen dam was constructed in 1949 by the local Little Willow Irrigation District, with a height of 43 feet and a length of 300 feet long at its crest.[1] It impounds Little Willow Creek for flood control and irrigation water storage, owned and operated by the local district.
The reservoir it creates, Paddock Valley Reservoir, has a normal surface area of 1,300 acres and maximum capacity of 36,400 acre-feet.[1] Recreation includes fishing for Yellow Bullhead, Crappie, Largemouth Bass, Smallmouth Bass, Bluegill, and Punkinseed Sunfish.[2] In 2008 the site was the tentative location of a nuclear power plant planned by MidAmerican Nuclear Energy, which was deemed not cost-effective.[3]
