Wahiawa Freshwater State Recreation Area is a state-managed freshwater fishing site on the shores of Wahiawa Reservoir (Lake Wilson) in Wahiawa, central O’ahu, Hawai’i, managed by the Hawai’i Department of Land and Natural Resources (DLNR). The area features the only public freshwater fishing access on O’ahu, shore fishing along the reservoir banks and boat fishing via a dedicated boat ramp, diverse freshwater species including largemouth bass, tucunaré (peacock bass with mandatory catch-and-release), channel catfish, Oscar cichlids, tilapia, and carp, covered picnic pavilions and restroom facilities, and a tranquil inland setting far from O’ahu’s crowded beaches.
Wahiawa Reservoir — locally known as Lake Wilson — is O’ahu’s only significant freshwater fishing destination and an unexpected oasis in the middle of the Pacific. The approximately 150-acre reservoir supports surprisingly diverse freshwater species for a Hawaiian island, including the prized tucunaré (peacock bass) — a hard-fighting tropical freshwater gamefish originally from South America that was introduced to Hawaiian waters.
The reservoir was created in 1906 by damming the North Fork of Kaukonahua Stream to provide irrigation water for the surrounding pineapple and sugar cane plantations of central O’ahu. Today it serves as Honolulu’s backup water supply and the island’s primary freshwater fishing spot.
Important restrictions: A valid Hawai’i Freshwater Game Fishing License and an entry permit are required to fish. Swimming, water skiing, and recreational boating (non-fishing) are strictly prohibited. No camping, no alcohol, and no pets are allowed on the grounds.
