Prosser Reservoir has some of the best bass fishing in the area right now. While the bass bite is good, most of the trout fishing has slowed down here. Anglers looking for bass should focus their efforts by the dam and prosser creek inlet near the campground. Some recommended bait choices for bass are inflated nightcrawlers, kastmasters, panther martins, rapalas, chartreuse powerbait, and various bass lures such as gitzit jigs or small spinner lures.

Prosser Creek Reservoir is currently at 45% capacity.
