Howard Water Diversion and Stream Crossings Project (Streambed Alteration Agreement No. 1600-2019-0377-R1)

Howard Water Diversion and Stream Crossings Project (Streambed Alteration Agreement No. 1600-2019-0377-R1)

The project is limited to 11 encroachments (Table 1). Three encroachments are for water diversion from unnamed tributaries to the South Fork Eel River. Water is diverted for domestic use and irrigation. Work for the water diversion will include use and maintenance of the water diversion infrastructure. Seven encroachments are to upgrade failing and undersized stream crossings. Work for these encroachments will include excavation, removal of the failing crossings, replacement with new properly sized crossings, backfilling and compaction of fill, and rock armoring as necessary to minimize erosion. One encroachment is for stream and riparian restoration by removing water storage tanks and implementing erosion control. Table 1.
