O'Neill Forebay, located next to the massive San Luis Reservoir, may be smaller in size but it packs a big punch when it comes to fishing for striped bass. This lake has gained recognition as a top striped bass destination, with multiple fly-fishing line-class world records. Aside from the impressive striped bass fishery, O’Neill also features good fishing for largemouth bass, crappie, and catfish.

Fall is considered the best time to fish at O'Neill Forebay for stripers, typically starting in late October when the cooler weather brings the fish to the surface. Typically, this is when the biggest fish are caught.

It's worth noting that O'Neill Forebay can get quite crowded, especially on weekends and holidays, throughout the warmer months.
