What is working right now

San Luis Reservoir striper fishing has been tough and on-again, off-again in late September 2025, with wind, temperature swings, and rising water moving fish daily. Work spoons and jigs on schools around 70 to 80 feet, or troll 5 to 7 inch stick baits 120 feet back on a downrigger at 2.2 to 2.5 mph. Roger George put one client on an 18.5-pound striper.

How is San Luis Reservoir fishing right now?

Tough. Numbers are hard to come by as the reservoir moves into fall. Wind, rising water temperatures, and incoming water have the striper bite on again, off again. Roger George rates it about a two or three out of ten, so be ready to search and cover ground to find fish.

What depth are San Luis stripers holding?

Fish are being worked around 70 to 80 feet on schools, with the day's better striper coming from about 70 feet. Coves are starting to become more defined and fish are moving in, but the main lake is where most anglers are focusing right now.

What lures and trolling setup work at San Luis?

Use spoons and jigs on schools, with 1-ounce dust-style spoons working well. For trolling, run 5 to 7 inch lures like Rapala, Smithwick, and Yo-Zuri, either jointed or straight stick baits, about 120 feet behind the boat on a downrigger at 2.2 to 2.5 mph on 20 to 25 pound mono. These are not Catch America products.

How big are the San Luis stripers?

Quality is there when you find them. Roger's group landed an 18.5-pound, 36.5-inch striper working about 70 feet, plus another near 30 inches at right around 10 pounds. It took a lot of work and moving from spot to spot to earn those fish.

What is the outlook for San Luis Reservoir?

Roger expects fall to become an awesome time once conditions stabilize. For now the lake is changing almost daily, so plan to search. Water temperatures were 72 in the morning rising to 75 to 76 degrees. The lake was taking on water on and off.

From the report (Roger George): The bite at San Luis has been difficult. Numbers have been hard to come by. We ended up with an 18.5 lb, beautiful 36.5-inch striper that we got working about 70 feet. I'm running them about 120 feet behind the boat on the downrigger at about 2.2 mph, using 20-25 lb test monofilament.
