Delta Aquatic Resource Inventory (DARI)

- Description:
- DARI is the Delta Aquatic Resources Inventory of surface waters, wetlands and other aquatic resources in the Sacramento-San Joaquin Delta (Delta). The goal of the DARI project is to develop a geospatial inventory of aquatic resources that will be used as a common base map for the Delta. DARI provides a standard regional approach to wetland classification and mapping to support wetland restoration planning, tracking, and reporting. It helps to facilitate implementation of the California Wetland and Riparian Areas Monitoring Plan (WRAMP) in the Delta. DARI was integrated into the California Aquatic Resources Inventory (CARI), a statewide standardized dataset intended to support regional watershed restoration planning and trackingwhich is publicly accessible on EcoAtlas (www.ecoatlas.org). DARI was developed using a Geographic Information System (GIS) and heads up digitizing, with true color imagery, LiDAR, and a suite of ancillary data sources to consistently map aquatic resources throughout the Delta. The draft GIS dataset was reviewed by regional wetland scientists and stakeholders to ensure it is accurate as possible. Aquatic features were hand-digitized while referencing ancillary national and local datasets for elevation, frequency of inundation, management, and previous mapping of streams and wetlands. Google Earth aerial imagery was used for confirming seasonal variations. Learn more about DARI mapping procedures and standards in the DARI Standards and Methods document. DARI may be periodically updated through a map stewardship effort. Local wetland scientists and managers can suggest updates to improve the accuracy and detail of the GIS dataset using the CARI Editor tool on EcoAtlas.
