By combining the historical record, data from ongoing streamgage monitoring, and data on new events, the USGS is able to develop the expertise and tools that help Federal, State, and local community leaders not only to enhance short-term preparation, aid, and recovery efforts, but to better understand how their flood risk may be changing over time and how they can reduce their risk in future events. (Larson, 2009, USGS General Information Product 93)

Systematic collection of flood records (peak stage and discharge) began in Oklahoma between 1930 and 1940. During that period, many continuous-record gaging stations (streamgages) were installed to define the flow characteristics of streams in Oklahoma. Some streams have records prior to 1930, but these records are generally fragmentary and in most cases only stream stages are available. Generally, the records prior to 1930 are for large basins only.

The spring and early summer months, April through July, have the highest occurrence of annual floods. More than two-thirds of all annual floods occur during these four months. December is the least likely month to have an annual flood in Oklahoma. (Sauer, 1974, WRIR 73-52)

USGS streamgages transmit real-time data about the stage and discharge of rivers to the National Weather Service and U.S. Army Corps of Engineers (among others), helping them to monitor, predict, and plan for approaching floods. Flood forecasts and warnings issued by those agencies allow responders to evacuate residents, prepare for disaster aid, and protect and save lives and property.
