Document Description
The Mattley Meadow Restoration Project (Project) would restore channel-floodplain connectivity in Mattley and Mattley Creek meadows at the headwaters of Mattley Creek, tributary to the North Fork Mokelumne River. The Project would eliminate incised gullies in the meadows. Construction will require one month during the low/no flow period (proposed for September 1-30, 2021). The Project would restore approximately 45 acres of riparian and meadow habitat (32 acres of federal lands, 13 acres on private property), enhancing wetland conditions on 30.86 acres of palustrine wetland (montane meadow), creating 1.61 acres of palustrine open water, and reconnecting 1,926 feet of riverine channel (0.64 acres) with the meadow floodplain. See NOC for full details.
