The downloadable ZIP file contains both Esri shapefiles and KMZ files.The Lapwai Creek watershed planning layers dataset was compiled as part of a watershed planning effort for the Lapwai Creek watershed in Nez Perce and Lewis Counties, Idaho.  The 174,600 acre watershed is a priority for steelhead habitat restoration.These data layers are part of a larger spatial data set used for the development of the 2009 Lapwai Creek Ecological Restoration Strategy. This strategy focuses on steelhead habitat restoration within the watershed.  The planning effort was conducted jointly by the Nez Perce Tribe and the Nez Perce Soil and Water Conservation District.  The planning effort was funded by the Bonneville Power Administration through their Fish and Wildlife program.The data set contains both shapefiles and KMZ files for use in GIS software and Google Earth applications.The data sets included in this release are described below. As data sets are processed and time and resources allow, additional releases will be published. Lapwai Creek 300 ft BufferData set is a 300 foot stream buffer along streams within the Lapwai Creek watershed near Lapwai, Idaho. Layer developed by Dash Dieringer and Lynn Rasmussen, Nez Perce Soil and Water Conservation District. September 2007.Lapwai Creek 500 ft BufferData set is a 500 foot stream buffer along streams within the Lapwai Creek watershed near Lapwai, Idaho. Layer developed by Dash Dieringer and Lynn Rasmussen, Nez Perce Soil and Water Conservation District. September 2007.Hydric SoilsData generated from USDA Natural Resources Conservation Service Soil survey, using the soil attribute for hydric rating. Hydric soils were selected and clipped to the boundary for the assessment units within the watershed. The data layer was developed by the Dash Dieringer and Lynn Rasmussen, Nez Perce Soil and Water Conservation District, Culdesac, Idaho. August 2007. MUSYM = soil number as assigned in the Nez Perce /Lewis Soil Survey (USDA Natural Resources Conservation Service). There are 13 assessment units within the watershed. Data is organized by assessment unit boundary.Hydric soils are formed under water saturation, flooding or ponding which occurs for a long enough period of a growing season to develop anaerobic conditions. The hydric soils rating was used for the watershed planning process to identify geographic areas with water saturation and potential wetlands.Assessment UnitsLapwai Creek watershed assessment units developed for use in the watershed plan. 13 assessment units were defined by juvenile steelhead density and distribution breaks. Steelhead density data was collected by the Nez Perce Tribe. Assessment Unit shape delineation and geospatial processing was completed by Dash Dieringer and Lynn Rasmussen, Nez Perce Soil and Water Conservation District. Culdesac, Idaho. August 2007.RoadsLapwai Creek watershed roads spatial data are categorized by surface type: dirt, gravel, paved. Data was obtained from Nez Perce County and clipped to the watershed boundary. geospatial processing was completed by Nikki Lane and Lynn Rasmussen, Nez Perce Soil and Water Conservation District. Culdesac, Idaho. 2012These data were contributed to INSIDE Idaho at the University of Idaho Library in 2015 & 2016.
