San Luis Reservoir is fishing up and down in late July 2026 as heavy wind stirs algae and holds the water temperature at 71 degrees. Capt. Roger George is trolling the main lake flats in 60 to 80 feet of water at 2.2 to 2.4 mph, running lures 120 to 140 feet behind the boat. White belly and chartreuse are the top colors. One recent trip landed fish of 14, 21, and 27 pounds.
What is biting at San Luis Reservoir right now?
The bite is up and down as constant wind churns the lake. Capt. Roger George had an epic recent trip with guest Bob McGill, landing fish of 14, 21, and 27 pounds, then a tough follow-up trip. Big fish are still figuring out where the bait has moved. The report did not name a specific target species.
What depth are the fish holding at San Luis Reservoir in late July?
Roger is fishing the main lake flats that run about 70 feet deep, trolling in water 60 to 80 feet deep. As the surface warms toward 80 degrees over the next week, expect fish to slide deeper, likely down to 70 to 80 feet. Watch your sonar daily since depth shifts with wind and overcast.
What lure colors are working at San Luis Reservoir?
White belly patterns are helping out right now, and chartreuse is producing as well. Colors can change day to day with the wind and light, so Roger's rule is to let the fish tell you what they want rather than committing to one pattern. Specific lure models were not named in this report.
How is Roger George rigging and trolling at San Luis Reservoir?
He is trolling 2.2 to 2.4 mph and letting lures back 120, 130, and 140 feet behind the boat, running through water 60 to 80 feet deep on the main lake flats. He leans on his sonar to find the depth fish are holding at and whether they are active before committing to a zone.
What are conditions like at San Luis Reservoir?
The lake is holding stable near 50 percent, with water being pumped in and out, which stirs in grass, debris, and algae. Water temperature is only 71 degrees, well below normal. Heavy wind is the biggest factor, and shore anglers have been doing a little better than boaters because wind limits boat time.
What is the guide's outlook for San Luis Reservoir?
Roger expects temperatures to rise toward 80 degrees over the next week, which should move fish deeper and change the pattern again. His forecast is decent fishing coming up if you can handle the summer heat. Water clarity beyond the algae mixing was not specified in this report.
