Water Diversion and Diversion Facilities. Water diversions covered under the Template SHA include diversions of surface water through conduits or openings from streams, channels, or sloughs within the Covered Area by a Permittee in accordance with a valid water right including the following activities associated with water diversion and diversion structures: - Ongoing management and/or maintenance of existing flashboard dams, including the placement of boards into concrete abutments across the wetted channel to build head to divert water, and the removal of the boards. - Ongoing maintenance, management, and repair of boulder weirs. - Installing, operating, maintaining, and removing push-up dams or weirs. These are defined as temporary diversion structures created by using loaders, backhoes, or excavators to move bedload within the stream channel to form a flow barrier or xxxx that seasonally diverts a portion of the flow of the stream. - Installing, operating, maintaining, and removing other temporary diversion structures that are not push-up dams. “Other temporary diversion structure” is defined as any temporary structure to divert water seasonally from a stream and is typically made with hay xxxxx, hand-stacked rocks and cobble, tarps, wood, and/or a combination of these materials placed in the channel with or without the use of heavy equipment. Equipment may be used from the bank but not within the channel. - Installing or placing pumps and sumps and maintaining existing pumps and sumps within or adjacent to the active channel of a stream, which sometimes requires the use of large machinery within or adjacent to the active channel. - Installing head gates and measuring devices that meet NMFS and CDFW standards and is done in compliance with California Senate Xxxx 88 on or in a diversion channel, which usually is done by excavating the site to proper elevation using large machinery, positioning the head gate and measuring device at the appropriate elevation, and installing rock or other “armoring” around the head gate to protect the structure. During installation, the stream bank could be affected by the construction of concrete forms and other necessary construction activities. - Operating head gates and measuring devices, including operation by the Watermaster on behalf of Permittee. The following AMMs may be applicable to the activities described above (specific AMMs for each Enrolled Property will be listed, as appropriate, in individual Site Plan Agreements):
