DESCRIPTION
This project sponsored by the Asotin County Conservation District planted and provided supplemental watering to the lower 500 foot reach of Pintler Creek at the confluence with George Creek as well as a 2,000 foot reach of the lower section of George Creek, southwest of Asotin, Washington. The Snake River Salmon Recovery Plan identifies both streams within a major spawning aggregation (MSA) and a priority restoration reach. Snake River Steelhead is the primary target species with Chinook salmon a secondary benefited species.
The 1996-97 floods heavily impacted lower George Creek. In an effort to improve stream and riparian areas, the landowner enrolled 37 acres in CREP. Also, the District received funding from SRFB and completed a 5,115-foot channel meander reconstruction project in 2005. Trees were planted at the project site in 2006 using BPA and Ecology funds. The plantings were successful for the most part; the exception being willow plantings on the lower end of the meander project. This project replanted the reaches that were not successfully planted in 2006. The project goal was to establish as much ground cover vegetation as quickly as possible. Expedited riparian vegetation establishment will enhance streambank stabilization, provide shade and cover to the stream and cobble landscape adjacent to the stream, reduce heat sink impacts to subsurface flows, promote biomass recruitment on the cobble landscape, and enhance stream flows and temperature.
13,000 willow whips were mechanically planted with a stinger over three consecutive spring planting seasons, 2008, 2009, 2010, along with 500 western junipers that were planted on the flood plain in 2009. Supplemental watering with this SRFB grant was done in 2009 and 2010 only. The 2008 plants that survived without supplemental watering, not many did, were watered in 2009 and 2010 along with the new plantings. The district was granted a one year extension to this grant after the failure of the 2008 planting to give us two more seasons to establish the plantings.
