Fishing San Luis Reservoir: what the data says
12,700-acre reservoir near Los Banos. The wind-blown striper bowl off Pacheco Pass. Pumped Delta water stacked with stripers chasing bait on the dam face. The lake tops out around 274 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Species by species, here's what the data says the year looks like.
On the chart, San Luis Reservoir draws 12,837 acres inside 58 miles of shoreline — one island included. That shoreline is heavily fingered (development index 3.7) — bays, points and pockets everywhere, which multiplies the fishable edge. 22% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water.
Striped Bass fishing at San Luis Reservoir
When the water first warms, striped bass slide up into 5 to 20 ft. Summer is a 25 to 60 ft game here, winter a 20 to 50 ft one. Start at San Luis Creek inflow.

Keep a flutter spoon (deep) or a umbrella rig (trolled) rigged through the warm months.
