What is working right now

San Luis Reservoir is moderate to slow in mid-September 2025 after a full moon and up-and-down temperatures. The lake is up to about 920,000 acre-feet and rising. Troll Rapalas in shad colors 100 to 120 feet behind the boat at 2 mph, targeting 60 to 70 feet deep. Roger George's buddy caught a striper over 26 inches, with the average fish still around 20 to 21 inches.

How is San Luis Reservoir fishing right now?

Moderate to slow. Roger George says the full moon and up-and-down temperatures slowed the bite. Trolling took all day to find fish, but his buddy Sonny landed a nice striper over 26 inches, and they boated a couple more. The average fish is still 20 to 21 inches.

What lures are working at San Luis Reservoir?

Rapalas in shad colors are producing the trolling fish. Topwater rip baits work in small windows when you find them, but the overall bite is slow. Covering ground to locate active fish has been the key this week.

How deep and fast should you troll San Luis?

Roger runs about 100 to 120 feet behind the boat at 2 mph, focusing on 60 to 70 feet deep in the main lake. That main-lake trolling program has produced his best success, with occasional cove boils early and late.

What are the San Luis water conditions?

The lake is up to about 920,000 acre-feet and rising a half to three-quarters of a foot a day. Surface temperatures are up to 80 degrees, and thick algae drops visibility to nearly zero in some areas, which will affect fishing next week.

What is the outlook for San Luis Reservoir?

Roger rates the bite about a 2 out of 10 right now. He hopes stabilizing temperatures and rising water will improve it. Come ready to cover ground, find the fish, and then target them.
