A crisp, open sky after dark, with a light NE breeze and the barometer holding steady. Activity on Patterson Reservoir should centre on rip-rap and rocky transitions. The productive run goes the day. Start on the obvious water and expand from there. Falling temperatures are switching fish back on.

Patterson Reservoir belongs to Alameda County, California. It sits at 699 feet above sea level. The water measures roughly 5 acres, so nothing here is far from anything else. Most waters listed here for Alameda County are larger. Nearest place of any size is Livermore, 4.8 miles away. The nearest city of size is Fremont, 20 miles away. It sits well inside its county, with no border complications.
Depth is not on record here, so the bank has to tell you. The arms fish better than the open middle whenever the water is up. Rip-rap along the wall holds fish that the open bank never does. Across Alameda County, recorded fish include Chinook salmon, common carp, striped bass, rainbow trout and Sacramento sucker. At least one recorded species is protected in parts of its range; read the local rules before targeting anything. On Patterson Reservoir that means starting tight and working out.
Averages move between 47°F in January and 73°F in August. The hard part of the year is the heat, not the cold. October and November give a second good stretch as it cools. February into May fishes hardest as the water warms. That is the shape of the year on Patterson Reservoir. Water colour tells you more than the air temperature does.
Public sources are silent on who controls the bank. There is no mapped parking or launch nearby, which keeps numbers down. A small crankbait along the drop and a worm in the thick stuff cover the bass. Parking space is the usual limit rather than the bank itself. Signs go up and come down, so check on the day. For a change of water, Frick Lake is 2.7 miles distant. Nothing on Patterson Reservoir should be assumed from this page alone.
