Lake or Streambed Alteration Agreement No. 1600-2018-0093-R1 - Humboldt Redwood Company Gravel Bar EXtraction PRoject

The project is limited to one encroachment for aggregate extraction from 10 separate gravel bar sites along 23 river miles of the Eel River for commercial purposes. The Permittee shall extract no more than 150,000 cubic yards per year. No more than 30,000 cubic yards shall be extracted from any single site within any given year. The annual extraction rate at any single site shall not exceed 15,000 cubic yards averaged over ten years. Thus, the upper extraction limit cannot be exercised on all sites within the reach in any given year. The specific bar, location on the bar, method of extraction, and volume of extraction (not to exceed 30,000 cubic yards) may change annually as river conditions change from year to year. Water diversion for use is not a covered activity under this agreement. Aggregate extraction consists of removal of flood-washed alluvial material using heavy equipment (e.g., belly-scrapers, loaders, excavators, bulldozers, and dump trucks) from outside the Eel River wetted channel. Aggregate extraction methods and volumes are consistent with the approved annual extraction work plans. Extraction occurs during the summer low-flow period when alluvial deposits are exposed. Occasionally, fisheries enhancement or off-channel extractions may be included that involve connection of extraction areas to be the wetted channel or removal of established woody riparian vegetation. Temporary crossings of the wetted channel may be needed to access gravel deposits. Timing of the installation and removal of these crossings is conducted to avoid periods of peak flows and salmonid migration and spawning. Crossings are also designed to minimize the extent of channel disturbance and avoid sensitive aquatic habitat.
