The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement number 1600-2018-0710-R1, pursuant to Section 1602 of the Fish and Game Code to Shasta Valley Resource Conservation District.
The project is limited to modification of the existing Montague-Grenada measurement weir on the Shasta River to provide unimpaired salmonid passage throughout all life stages, as depicted in final plans prepared by Cascades Stream Solutions dated June 21, 2019 and as accepted by CDFW Engineering in an email dated May 31, 2019. Equipment may include excavators, backhoes, cement saws and machinery and tools for pouring concrete, dump trucks, pick-ups, and equipment carriers or lowboys. Access to the site will be from Montague-Grenada Road and instream work area will be isolated from the Shasta River. Minimal equipment will be in the Shasta River as much of the work can be done from the right bank. Water within the work area will be pumped onto the adjacent floodplain/terrace and allowed to infiltrate away from the stream. Vegetation will be removed along the north bank above and below the existing weir and measurement facilities with one to two excavators/backhoes Some bank excavation will also occur. Upon completion, Permittee will manage flashboards for an interim period until another party is identified to perform this task. Vegetation and sediment maintenance will be performed by the Scott Valley and Shasta Valley Watermaster District.
