Contra Costa County Fishing Reports

The early summer bite is shaping up differently across the Delta depending on which side you’re fishing. On the Sacramento side, striper schools are thinning as they drop toward cooler Bay water, but there’s still action if you cover ground. Anchored boats are picking off fish with cut sardines between Clarksburg and Sacramento, while deep trollers are scoring along the West Bank from Rio Vista to Collinsville with Yo-Zuri Crystal Minnows.

Liberty Island is one of the better zones for both largemouth and stripers right now. Shallow water... two feet or less... is holding fish tight to cover, and chatterbaits are doing the work. Sturgeon are still hanging in Suisun Bay, but most folks have moved on. It’s catch-and-release only.

On the San Joaquin side, the largemouth bite’s consistent for 2 to 3 pounders. Topwater baits are working along rocks and weeds, working best with long pauses between movements. When it’s windy, crankbaits, chatterbaits, and spinnerbaits in craw or bluegill patterns are producing. Soft plastics in natural tones are still working in calm tighter pockets.

Stripers are more scattered. The western Delta’s mostly quiet, but Three Mile Slough is still giving up smaller fish on shad-pattern spoons. For keepers, Mossdale is the best shot... daytime gets you shakers on frozen bait, but the 8 to 10 pm window is the key for 23 to 30 inch fish on jumbo minnows.

The Delta threw plenty of curveballs this week. Water temps hovered around 70 degrees with 3 to 8 feet of visibility, but consistent 15–20 mph winds made open areas tough to fish. The tides were mostly mid-day lows with short, late afternoon incoming cycles... leaving a tight bite window for both bass and stripers.

Striper action is fading as post-spawn fish trickle back toward the Bay. A few decent fish are still around, especially near deep edges and current breaks during the first hour of the incoming.

Largemouth reports were all over. Anglers covering water with chatterbaits and spinnerbaits in wind-blown cuts picked up decent numbers, but big fish were scarce unless you hit the right tide. Low tide frog bites are starting to fire in shallow grass, and drop shots are filling in when reaction baits stall. Most of the easy spawn fish are gone, but a few waves should trickle in with the next full moon.

San Pablo’s running hot with catfish… easy pickings off the docks and near Scow Canyon where they’re stacking up in the deeper slots. A second 3,000-pound catfish plant last week should keep the bite rolling into late spring. Look for tagged fish and grab discounts at the marina.

Bass are finally starting to wake up too. Spotted bass are hitting underspins and Keitechs near shad schools, which are starting to bunch up across the lake. Water’s sitting at 62°. Boaters are still benched with the launch closed to all private vessels (golden mussel prevention).
