Opis

Director's Order NPS-75 requires the National Park Service (NPS) Natural Resource Inventory and Monitoring Program to establish a Servicewide inventory of waterbodies and water quality use classifications. The Government Performance and Results Act of 1993 (GPRA) directs Federal agencies to articulate program goals in a quantifiable and measurable manner. These mandates are reflected in the mission goals of the 2000 NPS Strategic Plan. Included among these mission goals are the creation of a water resources inventory and achieving a target of 85% of 265 park units with unimpaired waterbodies. To help achieve the goals of NPS-75, GPRA, and the NPS Strategic Plan, this report summarizes for Dinosaur National Monument (DINO): (1) Clean Water Act (CWA) State- designated uses; (2) CWA 303(d) quality impaired waters and causes; (3) special designations recognizing waters of exceptional quality as defined in State water quality standards; and (4) hydrographic statistics based on the United States Geological Survey (USGS) 1:100,000 scale National Hydrography Dataset (NHD). Data sources used to compile this report include: Environmental Protection Agency (EPA) Total Maximum Daily Load Tracking System, EPA Water Quality Standards Database, EPA National Assessment Database, EPA EnviroMapper for Water, USGS NHD, the Colorado Department of Public Health and Environment - Water Quality Control Division, and the Utah Department of Environmental Quality - Division of Water Quality.
