SRWMD Water Data Portal

The mission of the District’s Water Resources Monitoring program is to provide quality-assured water data for use in research, planning, public safety, recreation, and education. The District is committed to documenting our hydrologic conditions for present and future stewards of the unique water resources in our community.

The data sources below are intended for general use. Use the maps for browsing and the inventories for choosing stations based on your needs. The time-series data are presented in Microsoft Excel 97-2003 format. If you can’t open these files, you can download a free Excel viewer. If you need large data sets that include many stations, we can provide, by request, a variety of formats that could reduce your “data-mining” efforts.

Sometimes hydrographers will estimate missing values or make observations about how the data was derived. In these sets you will see a column of quality codes in addition to the time-series data. These codes provide you with background information on data reliability. You can access a list of codes and their definitions.

Hydrologic Conditions Reports
These monthly reports compare current conditions to historic data.

River Data
Important: The archive map contains links to external U.S. Geological Survey (USGS) websites. Most USGS stations show river levels that have not been adjusted to a survey datum. This means the numbers on the USGS site will not be the same as the ones you see on the District webpage or most National Weather Service forecast sites. If you use USGS data from their webpages for flood information or construction-related activities, it is critical that you adjust the data to the survey datum you are using. Use this guide for more information.
Nitrate Concentrations at a Glance
Nitrate can affect the health of our groundwater, springs, rivers and estuaries. While the links above will lead you to tables of water quality data that include nitrate concentrations, this map shows graphs of nitrate concentrations at active groundwater and surface water stations.
Other District Data Available by Request
  • Doppler Radar daily rainfall estimates on a number of scales, from county-wide down to a 2-kilometer area. Data can be provided in maps or tables. Records begin in February 2001.
  • Biological data including algae and aquatic invertebrates on major rivers and streams. Records begin in 1989.
  • Groundwater data (levels and/or quality) for over 800 inactive stations.
  • Hourly data for a number of groundwater and surface water sites.
