Lake Murray Boat Rental and Concession in San Carlos is the sole on-water rental operation at San Diego's Lake Murray, a 171-surface-acre reservoir inside Mission Trails Regional Park. The concession stocks aluminum rowboats, small outboard motorboats, single and tandem kayaks, and stand-up paddleboards, all rented on a first-come basis with a valid driver's license and refundable deposit. Anglers working the concession's fleet target Florida-strain largemouth bass under a 12-inch minimum, plus channel catfish, bluegill, black crappie, and California Department of Fish and Wildlife winter-stocked rainbow trout. The same reservoir fishing infrastructure serves guided-trip operators and charter captains across the San Diego region, and anglers heading to offshore waters book through outfits such as Single Fin Sport Fishing in Allied Gardens for deep-sea species beyond the lake's freshwater lineup. Bait sales cover shiners, crawdads, nightcrawlers, mealworms, and wax worms, and the counter issues both fishing permits and California state fishing licenses. The reservoir enforces a 5-mph no-wake speed limit and prohibits swimming, and float-tube anglers must wear chest waders with a Coast Guard-approved PFD and 144 square inches of international orange visible above the waterline. Private boats, canoes, and kayaks launch from the ramp for a small fee, making the concession a staging hub for anglers who bring their own gear alongside those renting. A 3.2-mile paved perimeter path circling the reservoir draws joggers, cyclists, and dog walkers alongside the fishing and boating traffic, and ten barbecue stations with 64 picnic tables ring the shore. Lake Murray sits off Interstate 8 via the Lake Murray Boulevard exit in the 92119 ZIP, with the Kiowa Drive entrance leading directly to the concession and parking lot. The facility is managed by Rocky Mountain Recreation Company under contract with the City of San Diego Public Utilities Department. Post-paddle fuel in San Carlos runs through the Lake Murray Boulevard commercial strip, where Pure Press serves cold-pressed juices and acai bowls geared to the active-recreation crowd. Credit cards are accepted for boat rentals and concession purchases, though fishing permits require cash or exact-change payment at the iron ranger station when the counter is closed.
