Document Description
The project is limited to two encroachments for aggregate extraction from the channel
of the Mad River for commercial purposes. Due to excessive extraction concerns, federal permit restrictions on the annual volume of gravel extracted are implemented based on a flow-based analysis of gravel replenishment. The Permittee proposes continuing extraction according to the flow-based analysis currently in use. Over the last five years (2019 through 2023), total annual extraction volumes averaged approximately 21,000 cubic-yards (approximately 16,000 cubic-yards average from Johnson-Spini [with no extraction occurring in 2020]; approximately 5,000 cubic-yards average from O’Neill bar). Aggregate extraction consists of removal of flood-washed alluvial material using heavy equipment (e.g., front-end loaders, excavators, bulldozers, and dump trucks) from outside the Mad River wetted channel 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. 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, 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.
