The reservoir is open to fishing all year, but current conditions are unknown. Most yellow perch are small but a few 14-inchers have been caught. A few largemouth bass and brown bullhead are also being captured. Most crappie are likely suspended in deeper water.

Bureau of Reclamation biologists sampled the reservoir last year. Good numbers of crappie in the 10-inch range and some up to 14-inches have been captured. Largemouth bass catch rates in the nets were unusually high with five captured per net set. Yellow perch were also common with some up to 14-inches.

The reservoir is 70 percent full. With current lake levels ODFW expects a great crappie fishery in 2019.

Gerber Reservoir is a turbid reservoir. Bank access is good. Several boat ramps exist on the reservoir. Large bass boats can be launched at the Ben Hall Creek ramp. Most of the reservoir is on BLM property. A campground and fish cleaning facilities exist.
