Worthen Meadow Reservoir

Worthen Meadow Reservoir is a reservoir located in the Shoshone National Forest. The reservoir is fed by Roaring Fork Creek, and it holds around 1,500 acre feet of water with a surface elevation of 8,819 ft (2,688 m) (crest of the service spillway). The reservoir's two section earth-fill dam was constructed in 1958, and the reservoir acts as a supplemental supply of water for the City of Lander, Wyoming.[1] The total length of the dam is 917 ft (280 m) with a maximum height of 43 ft (13 m) above the stream bed of Roaring Fork Creek.

Recreation

edit

Numerous trails and campsites are located near the reservoir including Worthen Meadow Campground and trail-heads leading into the Wind River Range.[2]

Wildlife

edit

The reservoir contains different species of fish including rainbow trout, brook trout and arctic grayling.[3]

Safety Concerns

edit

The reservoir's upstream location 17 mi (27 km) from Lander creates a significant hazard to the city in the event of dam failure.[1] However, the dam has been reinforced and maintained to avoid failure.
