The gauges are monitored through the use of the USGS National Water Dashboard (NWD).
This dashboard is available to the public. The NWD is a mobile, interactive tool that provides real-time information on water levels, weather, and flood forecasts - all in one place on a computer, smartphone, or other mobile device. The NWD presents real-time stream, lake and reservoir, precipitation, and groundwater data from more than 13,500 USGS observation stations across the country.
The USGS monitors and maintains the gauges as a part of a cooperating agreement with the City. The agreement is a 75% (City) - 25% (USGS) split that will be executed with a 5-year agreement.
