Prosser Creek Reservoir is getting better post spawn. The lake is delivering steady action for both trout and bass. Shore anglers near the dam and Alder Creek Cove are doing well on PowerBait, worms, and salmon eggs—especially during the first and last hours of light. Fly anglers are picking up fish on zebra midges and small nymphs under indicators. Water temps in the mid-to-high 50s°F are keeping fish active, and bass are beginning to push into the shallows. Shore access is somewhat limited due to high water, but productive if you’re mobile. Prosser Creek Reservoir’s current water level is around 96% of its normal capacity.
