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 8819feet (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. The total length of the dam is 917feet with a maximum height of 43feet above the stream bed of Roaring Fork Creek.
Numerous trails and campsites are located near the reservoir including Worthen Meadow Campground and trail-heads leading into the Wind River Range.
The reservoir contains different species of fish including rainbow trout, brook trout and arctic grayling.
The reservoir's upstream location 17miles from Lander creates a significant hazard to the city in the event of dam failure. However, the dam has been reinforced and maintained to avoid failure.
Townsend Creek is a SNOTEL weather station located roughly halfway between Worthen Meadow Reservoir and Frye Lake at an altitude of 8700 feet (2652 m). Townsend Creek has a subalpine climate (Köppen Dfc), with long, cold winters and short, mild summers.
