Trout fishing is good at Los Vaqueros. Catfish were “infrequent” last week while stripers remain slow. Our water clarity remains good. Water temperature increased to 65-66 degrees.   

We’re open from 6 a.m. to 8 p.m. every day with boats due back at 6 p.m. We will be open regular hours on Memorial Day.  

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.  The wind has settled down the past few days, but spring is usually a windy time at Los Vaqueros. 

The reservoir is storing 153,800 acre-feet of water, 96 percent of its 160,000 acre-foot capacity. This is the most water ever stored at Los Vaqueros. Pumping has stopped and we will see the reservoir slowly drop.

Last week, a 17.01 pound striper was caught on an anchovy and an 11.16 pounder was caught using chicken liver.

All of our trails that were closed due to golden eagle nesting are now open. Sadly, we did not see any golden eagle eaglets this year, last year there were four fledged from three nests.  

We’ll have our monthly free fishing clinic at the Marina on Saturday, June 3 from 9 a.m. to 11 a.m.  The clinic is a conversation about fishing at LV that is open to anglers of all ages and skill levels.


Fishing for trout continues to be very good.  They are being caught in South Cove and Oak Point as well as Cowboy Cove.  The baits of choice for shore anglers are garlic-scented PowerBaits, nightcrawlers or Kastmaster lures.  Trout average a pound and a half but range to over 5 lbs.  There was a 1,000 pound Lassen plant on May 18th.  We will be planting again this week. In 2017, we have planted 13,500 pounds of trout.  Light tackle is important for catching trout with 4-6 pound test being plenty.  Trout fishing is best in the morning, with fish being caught around the reservoir.

With boats, we are getting reports of fish being caught in Cox and Peninsula coves. Trolling for trout is going fairly well using Rapalas in Fire Tiger, trout and silver patterns. There is no need for line heavier than 6 lb test. Kastmasters from shore are doing well.


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.  If you catch any of undersized fish please release them gently and allow them to grow up. 


Striper fishing remains slow.  Shakers are the main action with striped bass.  We are still seeing a number of undersized fish being caught for every keeper.  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. Two nice stripers came out of South Cove this week.  A 17.01 pound fish was caught on an anchovy and an 11.16 pounder was caught using chicken liver.


Catfish are making infrequent appearances.  As the water warms we look to see more fish being caught.  For those wishing to target catfish, chicken liver and anchovies are the best choices of bait.

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.
