Nez Perce Soil and Water Conservation District

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 Buffer

Data 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 Buffer

Data 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 Soils

Data 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 Units

Lapwai 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.

Roads

Lapwai 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. 2012
