Moretto Spyrock Bottoms Stream Crossings and Water Diversion Project (Lake or Streambed Alteration Agreement No. 1600-2018-0263-R1)

Moretto Spyrock Bottoms Stream Crossings and Water Diversion Project (Lake or Streambed Alteration Agreement No. 1600-2018-0263-R1)

The project is limited to seven encroachments (Table 1). One encroachment is for water diversion from Rattlesnake Creek. Water is diverted for irrigation. Work for the water diversion will include use and maintenance of the water diversion infrastructure. The six other proposed 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. Project activities at all stream crossings shall require pre-construction surveys by a Designated Biologist only if surface water is present one week before construction or becomes present during construction. Permittee disclosed additional features of interest (Table 2). The Notification states these features in Table 2 are either in good condition and meeting current performance standards or will be addressed soon to eliminate potential impacts to fish and wildlife resources. Existing stream crossings disclosed in the Notification, but not included as 1602 projects with fees, are not covered under this Agreement. If maintenance (such as armoring) and/or replacement become necessary, that work must be covered by a major amendment or a separate Notification. The Notification also discloses the use of wells located at Lat/Long 39.7982, -123.5228. These well is presented as additional source of water for irrigation needs on the property. CDFW did not evaluate hydraulic connection of the well to surface water, nor was a hydrogeologic evaluation prepared by a licensed geologist provided for CDFW review. No other projects that may be subject to FGC section 1602 were disclosed. This Agreement does not retroactively permit any constructed reservoirs (including “ponds”), stream crossings, water diversions, modifications to riparian buffers, or other encroachments not described in Table 1.
