Name: Fish Habitat - Lake Tahoe
Display Field: Substrate2015
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: Surface and submerged littoral substrates in Lake Tahoe, CA, NV were mapped from high-resolution satellite imagery using Object-Based Image Analysis (OBIA) analysis techniques. The derived substrate classes were translated into three fish habitats classes (spawning, feed and cover, marginal) in order to evaluate the attainment status with environmental standards related to nearshore fish habitat and to improve map products used for land-use planning and regulatory purposes. The results confirm previous satellite mapping efforts that feed and cover habitats and spawning grounds are limited in distribution to distinct areas around the lake. Our results support the use of high-resolution satellite data for discriminating substrate variation at a resolution sufficient to inform regional planning. Management and land-use actions may consider additional focus on these areas to maintain Lake Tahoe littoral fish habitat characteristics.
