Low Flow River Closures begin Sept. 1 and run through April 30, 2025.
North Coast rivers that are regulated by low flow closures, including the Eel River, Mad River, Mattole River, Redwood Creek, Smith River and Van Duzen River will begin angling restrictions on September 1st, and run through April 30th 2025. . As a reminder, in 2022, a low-flow angling restriction was added to the section of the Eel River from the mouth to Fulmor Road (Eel estuary) at its paved junction with the south bank of the Eel River. When a low-flow closure occurs in this section of the Eel, it will be closed to hook-and-line fishing; other legal fishing methods are allowed during this timeframe. The Department of Fish and Game will make the information available to the public by a telephone recorded message updated, as necessary, no later than 1 p.m. each Monday, Wednesday and Friday as to whether any stream will be closed to fishing. The rivers can be opened up at anytime. Rivers will not automatically open to fishing once minimum flows are reached. The low flow closure hotline for North Coast rivers is (707) 822-3164. NOTE: The main stem Eel from the South Fork to Cape Horn Dam and the Mattole River will be closed until January 1, 2025.

Mattole River: The main stem of the Mattole River from the mouth to Honeydew Creek. Minimum flow: 320 cfs at the gauging station at Petrolia.
