Fernando Gonzalez of San Lorenzo caught his record-setting 16.42 pound trout with a gold Kastmaster in South Cove on Jan. 24, 2015.  It's the last record set at the reservoir, and beat the previous mark by .27 pounds.  


October 20, 2016

Fall fishing is underway at Los Vaqueros with small striped bass very present along with trout and catfish.

There was a 2500 pound DFW trout plant on October 12th.  There will be a plant later this week.  

The reservoir is currently storing 126,000 acre-feet of water, 79 percent of capacity. Pumping has stopped. The water temperature is slightly lower at 67 to 68 degrees. Our water clarity is fair to good.

The windy weather pattern is settling, but we still see plenty of breezy days. If you are looking to rent a boat, it is a good idea to call ahead at (925) 371-2628, check current conditions, or look at a forecast for the Livermore-area that is pretty close to our weather.

They won’t harm you, but we are seeing tarantulas.

The John Muir Interpretive Center near the dam is open from 9 a.m. to 4 p.m. on Saturdays and Sundays.

In October, we’re open from 7 a.m. to 6 p.m. with boats due in by 4 p.m.

In November, we’ll have night fishing on Friday nights until 8 p.m. 


Our striper fishing derby is continuing through October with prizes going to the three largest stripers caught. We’ve only had three entries, and the largest fish so far is only 3.18 pounds and 21 inches long. There are still 11 days to land a bigger fish.  The $5 registration fee can be purchased at the Marina. It is good for the entire month, and participants may weigh up to the daily legal limit of two stripers per day at the Marina. Call the Marina at (925) 371-2628 for details.


Fishing for trout continues to be good even with the increased water temperature.  They are being caught in South Cove and Oak Point as well as Peninsula Cove.  The bait of choice for shore anglers is garlic scented PowerBaits, nightcrawlers or Kastmaster lures. Trout average a pound and a half but range to over 5 lbs.  There was a 2500 pound DFW plant on October 12th.  There will be a plant later this week.  Light tackle is important for catching trout with 4-6 pound test being plenty.  Trout fishing is still decent, especially in the morning, with limits being caught from around the reservoir and a number of 2’s and 3’s showing up.

With boats we are getting reports of fish being caught in Cowboy and Peninsula coves.  From the shore, the most popular bait has been by garlic scented PowerBaits followed by nightcrawlers and Kastmasters.  There is no need for line heavier than 6 lb test.  Fish are still coming out of South Cove and from past the Rock Wall.


Most anglers were focused on stripers or trout although there still are many sighting near the boat dock and adjacent fishing pier and along the Rock Wall.  Senkos have been seen catching some nice fish in that area.  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.


We are starting to see striper boils around the lake, mostly early in the morning and towards closing.  Shakers continue to be the main action with striped bass.  We are still seeing many undersized fish being caught for every keeper.  The fishing pier by the Marina has been particularly good.  From shore, cut anchovies or shad is 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 hit or miss with fish being reported out of Cowboy and SouthcCoves.  As the water warms we look to see more fish being caught.  For those wishing to target catfish, nightcrawlers and chicken liver are the best choices of bait.  We encourage and appreciate the release of any monster catfish (15 lbs plus).


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.

Trout Derby Winner

Pat Parra of Campbell won the April Los Vaqueros Trout Derby with this 12.19 Pound catch, caught in the South Cove with a Kastmaster.  He won a Piranha Fish Finder. 

Kevin Tobeck from Tracy caught this limit of rainbows while fishing from the North Side of the Los Vaqueros Reservoir on April 19, 2016.  To get there is a bit of a walk.  Park at the Interpretive Center, and then walk over the dam.  There's a variety of fishing habitat, and not much of a crowd.  
This 8 pound largemouth was caught on the
 northside of the reservoir on March 26, 2016
 with nightcrawlers. 
Jan. 10, 2016 brought this rare double rainbow over the water at Los Vaqueros Reservoir.  Matt De la Madrid of the LVRC staff took this great shot from the docks at the Marina.
