The Jacoby Creek watershed is a part of the ancestral territory of the Wiyot native people. Historically the creek has been an important spawning habitat for salmon, steelhead, and even coastal cutthroat trout. The creek remains habitat for Coho salmon and other salmonids coming home to spawn.
Jacoby Creek is one of four major tributaries of Humboldt Bay on the North Coast of California. While the paths of the other tributaries of the bay have been altered, the course of Jacoby Creek has been left much as it was at the time of European settlement. The creek drains a watershed of 17.3 square miles.
