Lake Barrett has attained almost-mythic status among SoCal lakes. Completed in 1922, it was closed to the public until 1994, and has been managed ever since to try to maintain an extremely high quality of fishing.
The lake is only open 3 days/week, from May-Sept. There is no private powerboat launching, anglers must rent a boat or bring kayak boats or float tubes. Since you are on Ticketmaster, you probably already know access is limited to around 100 people or so per day. Fishing is 100% catch-and-release, with barbless hooks. The primary targets are northern strain largemouth bass, but the lake has a large population of large bluegill and crappy of the bass aren’t cooperating.
The lake is located close to the Mexican border, and while owned by the City of San Diego, is surrounded by private property. It’s accessed thru a single gate, then over a couple of miles of graded dirt road. 4x4 is not required, there are just a few rocky spots and some steeper sections, but nothing a passenger sedan can’t handle.
The City website is inaccurate in that the gate opens at 4:00am, not 5:00 am. The rental boat docks are at the bottom of a short, fairly steep hill from the lowest parking lot. No steps, just a dirt road. The rental boats are basic Jon boats with 6 or 8 HP outboard, so you will need to bring your own electric motor and battery. You might want to bring a wagon or hand truck to minimize trips back to the car.
The weather can be extremely warm June-August and there is little to no shade along the shore, so bring sun clothes, a wide brimmed hat, sunscreen, and plenty of water.
There is no concession stand, and boats are first-come-first-served, so pick a boat, load up, and go. Grab flotation cushions from the common dock box, or bring your own.
Barbless hooks are required, so be sure to crush the barbs on any flies or lures you tie on (you don’t have to do all your lures, just the one you have on). All of your standard Bass lures/flies will work, although most people focus on the top-water/shallow water bite. The predominant forage is threadfin shad.
Fishing is best in May and Sept, but can be good in the summer months as well, especially if the water levels remain stable. Most of the shoreline has a band of matted weeds and underwater moss
