Local¶

• SurfRider Water Quality Monitoring

• Project Clean Water. Centralized clean water resources for Southern California

• Waterboard Bacterial TDML for SD Beaches. The Data Sources section of the report has a lot of great pointers and suggestions. The data is available from CEDEN in the Beachwatch program.

  • TDML Projects Overview

State Sources¶

• CEDEN - California Environmental Data Exchange Network

  • San Diego Data Catalog
  • Beachwatch Program has the TMDL data

• USGS Water-Quality Data for California

• CA Water Boards Data and Databases

• West Coast Oceans Data Portal

National Data¶

• WATERS Watershed Assessment, Tracking & Environmental Results System. Unites several other datasets:
  • NHDPlus National Hydrography Dataset Plus
  • National Elevation Dataset ** Watershed Boundary Dataset
• EPA Water Quality Indicators Data Review
• ATTAINS Assessment, Total Maximum Daily Load (TMDL) Tracking and Implementation System
• NARS National Aquatic Resource Surveys
• National Water Quality Monitoring Council Portal ( This seems to be the best site for SD County data )
• USGS Water Quality Data

Weather¶

• NOAA Land-Based Station Data For daily or hourly rain totals
• NOAA Climate Data Onliine

Tools¶

• NWIS Mapper Good for flow measurements, especially daily data
• CEDEN Advanced Query

I love a clean San Diego may be able to provide data for trash. See Toxicity of cigarette butts, and their chemical components, to marine and freshwater fish ( There are many groups that do beach cleanup, but they don't record their data, don't centralize it. Plastics are a major issue. But no comprehensive policy. Ask CS for more details. Maybe we can work on centralizing the data. Maybe have a crowd source system )
