DESCRIPTION
Colville Confederated Tribes used this funding to implement a deferred rotational grazing system to reduce water temperature and sediment yield. Four miles of fence was created for multiple pastures, where livestock are excluded from the riparian area and rotated through annually. This system was facilitated by 12 spring developments and 3 hardened rock crossings. All management techniques were implemented according to NRCS standards. Decommissioning of roads and implementing grazing strategies continued a larger effort to restore salmon habitat in the Omak Creek basin.
Omak Creek, tributary to the Okanogan River, lies within the Colville Indian Reservation and contains ESA-endangered summer steelhead. The Omak Creek Watershed Plan and Environmental Assessment had identified natural resource problems resulting in high sediment and increased water temperatures. Roads were identified as the leading factor of increased sediment yield within the Omak Creek watershed. Sediment yield was also suspected to be high from the uplands due to sparse vegetative cover caused by poor distribution of livestock and season-long grazing. Bank failures due to the high sediment load not being transported though the system causes lateral channel migration and puts culverts in the road system at risk of failing and delivering sediment. Approximately 8 miles of road were identified in the Stapaloop Creek drainage, a tributary of Omak Creek. The road sections were selected based on condition, utility and location. Most road sections showed signs of severe erosion.
