Redwood Creek Watershed – Hydrological Unit 107
Redwood Creek flows from an elevation of 5,200 feet in a northwesterly direction to the Pacific Ocean about 35 miles north of the city of Eureka at Orick, California. The watershed is mostly forested, steep mountainous terrain, approximately 280 square miles in size. The watershed is quite narrow, averaging about 6 miles in width. The mainstem drops out of the headwaters to become a low gradient stream with short tributaries coming off of the steep hillsides. Redwood Creek is an important salmonid stream in the area. The lower portion and the estuary are within the Redwood National and State Parks; the upper watershed mostly private timber lands.
