Lower Otay Lake, located in San Diego County, spans over 1,100 acres. Its shoreline stretches 25 miles and is dotted with a diverse array of structure, including tules, submerged trees, and drop-offs. This habitat sustains an elite fishery with giant fish, most notably largemouth bass, although big crappie, catfish, and sunfish thrive here as well.

Trophy bass are a theme at Lower Otay, although they aren't easy to catch. The lake receives heavy fishing pressure throughout the year, especially during the spring and summer when the tournament season arrives. Still, the lake is open only a few days a week, which helps alleviate some of this pressure.

Fishing from the shore of Lower Otay Lake can be challenging because most of the shoreline is bordered by tules. Boating is the recommended way to fish these waters. Visitors can bring their own boat or opt for rentals. The boat ramp, rental services, and other amenities are situated on the west shore, and there's a fee for day-use and launching.
