Fishing Report

August 16, 2017


Trout fishing continues to be “good” at Los Vaqueros Reservoir this week. Striper fishing has slowed, though they continue to be caught with boils seen at times on the laket. Catfish are starting to show up in greater numbers, with an 8.3 pound caught in Cowboy Cove with an anchovy, and a 5.49 pounder from the fishing pier.

Our water clarity remains good. Water temperature remains at 71 degrees this week. 

Take a look at our Facebook page to see two videos of “striper boils” at the reservoir.

We’re open from 6 a.m. to 8 p.m. every day with boats due back at 6 p.m. Our summer hours continue through the end of August. Starting Sept 1, hours will start to get shorter and we’ll be open from 7 a.m. to 7 p.m.

If you are looking to rent a boat, it is a good idea to call ahead to check current wind conditions at (925) 371-2628 or check online here for weather conditions updated hourly. After a few weeks of calm, the wind has returned.

The reservoir is storing 152,200 acre-feet of water, 95 percent of its 160,000 acre-foot capacity. That number is up, the District has updated the way it calculates the amount of water stored in the reservoir. Pumping has stopped and the reservoir will continue to drop through the summer.

The Contra Costa Water District applied for state funds to expand Los Vaqueros Reservoir. There is more information here:


Fishing for trout continues to be good with a lot of activity at the fish cleaning station. They are being caught in South Cove and Oak Point as well as past the Rock Wall.  The baits of choice for shore anglers are garlic-scented PowerBait, nightcrawlers or Kastmaster lures.  Trout average a pound and a half but range to over 5 lbs.  There was a 1,000 pound trout plant on June 29th.  Water temperatures are currently too high to safely plant trout.  Light tackle is important for catching trout with 4-6 pound test being plenty.  Trout fishing continues to be fair, mostly in the morning, with fish being caught from around the reservoir.  There are lots of fish being caught from Oak Point to past the Rock Wall.  South Cove also continues to produce a good number of fish.  Limits are still being caught.


Most anglers were focused on stripers or trout.  Keep in mind that largemouth need to be 12 inches to be kept.  Please release any big largemouth bass you might catch, they are the future of largemouth bass fishing in the reservoir.  1000 8”-10” bass were planted on July 13th along with 2000 3”-5” fish.  If you catch any of undersized fish please release them gently and allow them to grow up.  There will be a plant of 8”-12” largemouth bass later this week.


Striper fishing is mixed with fewer shakers showing up but more medium to large fish being caught.  The pier by the Marina and from Oak Point south towards South Cove are doing decently.  From shore, cut anchovies or shad are the bait of choice.  Just a reminder, stripers need to be 18 inches or more to be legal.  Please release the small fish as quickly and carefully as possible.  They are the future of our striped bass fishery.


Catfish are starting to show up in greater numbers. With the warmer weather and fish plants they are beginning to be caught from South Cove to Cowboy Cove.  For those wishing to target catfish, chicken liver and anchovies are the best choices of bait.  There was a 1000 pound catfish plant on August 10th from Lassen.  There will be another plant next week.  A 8.3 pound cat was caught using and anchovy in Cowboy Cove along with an 5.49 pounder from the fishing pier.

Frozen Bait Available At North Entrance Gate on Weekends

We have frozen bait available for purchase at the North Entrance gate (near Brentwood) on the weekends.  We have anchovies, chicken liver and shad. You can only buy the frozen bait at the gate, not the watershed office.

Los Vaqueros, A Popular, Beautiful, Fishing Destination 


Los Vaqueros is not only the largest reservoir in the Bay Area, but has also become a popular fishing destination. 

Trout, stripers and catfish are commonly targeted. With the expansion of the reservoir in 2012, habitat for largemouth bass have been added and that fishery is expected to soon begin to produce exciting opportunities for largemouth anglers. 

The beautiful Los Vaqueros Marina on the reservoir's south side near Livermore offers fishing licenses, bait, snacks and electric boat rentals. 

On the north side of the reservoir near Brentwood, there are no services available, but anglers can park at the John Muir Interpretive Center and take a steep hike about a half-mile to fishing areas near the dam and in Peninsula Cove. 

Here is a map of the watershed. 

There are three fishing piers along the shore of the reservoir.  The pier near the Marina is ADA-accessible.

The Marina and the south entrance to the watershed is accessible from Vasco Road at the Alameda-Contra Costa County line near Livermore. Here are Directions. The lake has been stocked with game fish including rainbow trout, salmon, catfish and largemouth black bass. The reservoir is available for day use only. 

A California State Fishing License and a CCWD Daily Fishing Access Pass Permit ($5) are required for fishing. There is a $6 parking fee to enter Los Vaqueros.
