ODFW and BLM have restocked the reservoir with small numbers of largemouth bass, crappie, and hundreds of pumpkinseed sunfish in 2023.

This fishery seems to be slow due to turbid conditions.

Willow Valley is a very turbid, desert reservoir. The boat ramp is in good condition but there's no dock and launching might be difficult. The reservoir has lots of water.

Bass and crappie can be found at the habitat structures placed by BLM and ODFW in the past. Yellow perch are prolific in the reservoir but stunted. Fishing for largemouth bass typically peaks earlier than other lakes and reservoirs. Largemouth bass fishing should be fair in the Antelope Creek channel of the reservoir.
