Document Description
The Project consists of extraction of 33,600 cubic yards of gravel annually from the Guynup Bar on the Mad River near Blue Lake in Humboldt County, California. Extraction generally occurs in the same areas, but a different extraction plan is prepared and reviewed annually by various federal, State, and local agencies. Gravel extraction consists of excavation of aggregate from exposed bar surfaces and/or excavation of aggregate from deposits adjacent to the low-flow summer stream channel, isolated water bodies, and secondary channels. Temporary stockpiling of excavated material within the limits of the extraction area is allowed through October 1, when stockpiles must be removed at the end of each workday above the ordinary high-water mark. Excavated materials are hauled to the adjacent aggregate processing facility located off Hatchery Road. After the aggregate material has been removed to the approved extraction design grades, the extraction area is re-graded as necessary to leave no depressions or berms that may potentially trap fish or cause impacts to surrounding habitats. Temporary bridge crossings consist of a pre-cast concrete bridge deck on girders or railroad flat cars on concrete block and clean gravel-fill abutments. Temporary bridge crossings are sited to avoid potential fish spawning, holding, and rearing habitat. Appropriate crossing locations are typically shallow low-velocity water located away from riffle crests and pools. A multi-agency site visit is conducted at the conclusion of the extraction operation and provides any additional recommendations reflecting seasonal extraction plan and reclamation plan conformity.
