About the Wainiha River
The Wainiha River drains one of the wettest places on earth. It runs off the flanks of Mount Waialeale and the Alakai plateau down a steep, narrow valley on the north shore of Kauai, reaching the sea between Hanalei and Haena, and the valley it has cut is among the most dramatic on the island. Annual rainfall in its headwaters is measured in hundreds of inches, and the river responds accordingly: levels rise and fall fast, and a clear river in the morning can be brown and dangerous by the afternoon.
It is not a conventional fishing destination and it would be dishonest to present it as one. The Wainiha is first of all a native stream, and the fish that define it are the oopu, the endemic gobies that climb waterfalls to reach the upper valley, along with native shrimp and snails. These are culturally important, in places protected, and not a sport fishery. Introduced species occur in the lower river and the estuary, where tilapia are common and bass and bluegill turn up in the slower water near the mouth.
What draws visitors is the valley and the water itself. The lower river and its mouth are used for paddling and swimming when conditions allow, the beach at the mouth is well known, and guided activity along this coast is built around the landscape rather than around a catch. Much of the upper valley is remote, roadless and held in conservation and private hands, and it should be treated accordingly by anyone heading inland.
Anyone going near this water should watch the gauge and the sky together. The river reads discharge and stage but no temperature, and the numbers move quickly. Flash flooding is the real hazard on Kauai’s north shore streams, the same rain that feeds the river also closes the highway west of Hanalei on a regular basis, and local advice on current conditions is worth a great deal more here than any forecast.
