San Luis Reservoir Fishing Report | June 16, 2025

Report by Capt. Roger George
Roger George runs Roger George Guide Service and reports on San Luis Reservoir striper fishing for Catch America.
What is working right now

San Luis Reservoir is tough right now. The lake is falling about a foot a day, down 30 feet in a month to 1.1 million acre-feet, water is in the 70s with heavy algae, and stripers are deep in a major spawn. Roger George rates it two to three out of ten. Scout the main lake, troll a little deeper on calm days, and stay persistent for a shot at a big fish.

What is biting at San Luis Reservoir right now?

Stripers, but the bite is slow. Capt. Roger George rates it two to three out of ten. The fish are in a very big spawn and everything being caught is milting, so many fish are only interested in spawning and will follow lures without committing.

Why is the San Luis bite so slow right now?

Several factors stack up. The lake is dropping about a foot a day, down 30 feet in a month to 1.1 million acre-feet, which hurts stability. Water is in the 70s with heavy algae, and a recent full moon plus an active spawn have fish focused on spawning, not feeding.

Where are the fish holding at San Luis Reservoir?

Fish are in the main lake and running deeper as shallow areas like Portuguese Cove get shallower. On calm days with good light penetration, trolling and focusing a little deeper helps. Locations shift day to day, so scout to find them.

What techniques work at San Luis Reservoir now?

The game is finding the fish first, then figuring out what they want, whether trolling, jigging, or spooning. Once you mark fish on your electronics, work to get them active. Patience is key during this unstable, high-pressure spawning period.

What is the outlook for San Luis Reservoir?

It will be difficult until the lake stabilizes, but Roger expects some relief and a better bite fairly soon. A few big fish are still being caught during the spawn. He recommends staying persistent. Specific lures were not specified in this report.
