Document Description
The project is limited to one encroachment for aggregate extraction from the channel of the Van Duzen River and Eel River for commercial purposes. The gravel extraction volume approved under a Vested Rights Determination by the County of Humboldt is 150,000 cubic yards of gravel annually from the Hauck Bar. Over the last five years (2019 through 2023), annual extraction volumes averaged approximately 35,000 cubic-yards. Aggregate extraction consists of removal of flood-washed alluvial material using heavy equipment (e.g., front-end loaders, excavators, bulldozers, and dump trucks) from the Van Duzen River and Eel River channels and adjacent areas. Aggregate extraction methods and volumes shall be consistent with approved annual extraction work plans. Extraction occurs during the summer low-flow period when alluvial deposits are exposed. Fisheries- and riparian-enhancement or off-channel extractions may be included annually and involve connection of extraction areas to the wetted channel and reshaping of the low flow channel to enhance passage conditions. Often, the channel at Hauck bar lacks surface flow during the extraction season, however, temporary crossings of the wetted channel may be needed to access gravel deposits in wet years, or years when seasonal precipitation events cause surface flow to re-occur. If the channel becomes “re-wetted” during operations, the Permittee shall immediately contact CDFW to coordinate the installation of temporary crossings. Timing of the installation and removal of these crossings is conducted to avoid periods of peak flows, salmonid migration and spawning, other aquatic organisms, and requires coordination with CDFW scientific staff. Crossings are also designed to minimize the extent of channel disturbance and avoid sensitive aquatic habitat.
