What are the conditions at San Luis Reservoir right now?
The reservoir is falling about a half foot a day and sits at 1.3 million acre feet, roughly 65 percent and slowly dropping. The pro staff hopes it stabilizes soon. The biggest factor is a heavy algae bloom that has kicked in with water temperatures reaching as much as 75 degrees, dropping visibility to as little as an inch or two in some areas.
How is the bite at San Luis Reservoir?
The algae bloom and the spawn have changed the bite. Many fish are still spawning and simply not interested in biting. A lot of the fish being caught are actively spawning, and the majority are males. The spawn at San Luis tends to run longer than at many other lakes.
Why are so many fish not biting?
Groups of fish are locked into spawning mode. You may see plenty of fish that will not eat because they are focused on the spawn rather than feeding. That behavior can confound anglers who mark lots of fish but cannot get bit.
What about the wind at San Luis?
Temperatures have been up and down like a roller coaster, and the wind in the San Luis pass is heavily affected. Some days the wind gets strong enough to close the lake. Pick a day when the wind is not too bad before you make the run.
