Striped bass, trout and catfish continue to provide the best fishing action at Los Vaqueros Res.

Los Vaqueros Reservoir - Livermore, CA (Contra Costa County)

by Los Vaqueros Staff
(925) 371-2628

We had some really large catfish caught again this week. The water level is now 130,000 acre feet. This is more water than the reservoir has ever held. We anticipate the water level to stay about the same this week. Our water temperature is 70-72 degrees depending on the day, depth of the water, wind conditions and air temperature. Our water temperatures should begin to drop as we go through the month of September.

Rattlesnakes continue to be out and active so caution is advised. Watch where you are walking, stay out of high grass and stay out of rocky areas. During August they are more active in the mornings and late in the afternoon or evening hours. Never try to pick one up or kill one.

We are in the fire season so extreme caution with any fire sources is required. We do close barbeques on extreme fire danger days. Extreme caution is advised when fishing or hiking on very hot days.

Fishing at the North End of the reservoir is now more easily accessible. A 15 minute hike (depends on what kind of shape you are in) will get you to an area with about 200 yards of open shoreline. Caution on the trails is advised. We also suggest (as always) being snake aware. This area is accessed by a short hike from the Dam. We anticipate fishing being very good in this area. The fishing platform still needs about 2 feet of water to be usable.

The Interpretive Center is open from 9:00am to 4:00pm on Saturdays and Sundays. September hours are 7:00am to 7:00pm with boats due back by 5:30pm.

Fish Plants
We planted 1233 lbs. of channel catfish averaging 2 lbs on Friday July 19. We planted 515 lbs of catfish on August 9. We continue to wait for cooler water temperatures before we plant trout. We anticipate frequent trout plants beginning late this summer or early this fall.

We are still giving out Whopper mugs. Our program has changed some so check with us at the marina. It takes a 5 lb trout to earn a mug, 12 lb striper, 12 lb catfish or a released 5 lb largemouth bass.

We have 2013 State of California Fishing Licenses for sale at the marina. Fish and Game has been checking fishing licenses so make such you have one for everyone 16 and over. We suggest taking advantage of the second rod stamp that is available.

Fishing for catfish continued a solid choice last week. Anchovies, liver, mackerel and nightcrawlers all caught catfish. We suggest fishing with as little weight as possible and watch for very soft bites. The back of cowboy cove, peninsula cove and the south cove are good bets. We encourage and appreciate the release of any monster catfish (15 lbs plus). We had several catfish over 10 lbs caught and released this week.

We had a 27.21 lbs catfish caught on Sunday. This monster was caught by Eric Hao, pictured above in cowboy cove using shad. The next day Anthony Tern caught a 24.44 lbs catfish on anchovy fishing in cowboy cove.

Fishing for trout has been fair depending on your skill and luck level. Trout average a pound and a half but range up to 4 lbs. Limits has been difficult to come by but we see a few limits each day. Many of the points east of the marina and past the Rockwall have been producing some trout action. The south cove also continues to be a regular producer of a few nice fish. Garlic power bait in rainbow, chartreuse power bait, orange mice tails and nightcrawlers are all good choices. A few anglers have been fishing nightcrawlers under slip bobbers and having success. Garlic scent on any bait seems to help. It is important to use 3-4 feet of leader. Using light line also helps; 4 to 6 lb test is plenty. There is no need for heavy weights. Vary your casting length; sometimes shorter casts are better than longer ones.

Trolling for trout continues to be slow but a few anglers continue to catch a some nice trout. The successful reports we are receiving are from anglers trolling a variety of lures off of points and in the mouths of major coves. Mix it up until you start catching fish. The fish seem to be holding between 12 and 18 feet. A few fish have been caught at deeper levels. Vary your depths until you start getting strikes. Look for areas that have the best visibility and are free of algae. Anglers trolling catch trout on a variety of lures including kastmasters, roostertails, rebels, rapalas and Thomas Buoyant. We continue to wait for cooler water temperatures before we plant trout. We anticipate frequent trout plants beginning towards the end of September. Trout fishing will improve as the water cools. We anticipate some great fishing this fall.

Not many anglers are focusing on largemouth so we have little to report here. Bass fishing is considered slow. Please release any big largemouth bass you might catch. They are the future of largemouth bass fishing in the reservoir.

Fishing for stripers with bait is an up and down affair but some anglers are catching limits of 18 to 23 inch fish. There were several nice limits of stripers caught in Cowboy cove this weekend and again on Monday. It seems to be good for a few days then drops off only to pick back up a few days later. Cut anchovies or shad will do the trick when bait fishing. Stripers need to be 18 inches or more. We are seeing a tremendous number of under size fish being caught and released. Sometimes anglers catch dozens of small fish from 8 to 17 inches. Please release the small fish as quickly and carefully as possible. They are the future of our striped bass fishery. We have not seen any large striped bass caught recently. Fishing from the pier below the marina has been a good bet. Anglers trolling continue to pick up a few stripers on a wide variety of lures. Bait fishing currently is the best way to go. We are just beginning to see some stripers chasing bait fish on the surface. It should not be long before trolling picks up.

Open seven days a week 7:00am - 7:00pm
Boats are due in by 5:30pm.

We encourage all anglers to report their stories, comments, or concerns to the Marina. Or, email Thanks again for choosing Los Vaqueros Reservoir as your recreation destination.
