Summary
The U.S. Geological Survey (USGS) Oklahoma-Texas Water Science Center, in cooperation with the Oklahoma Department of Transportation, updated basin-characteristic data for Oklahoma streams with drainage areas of less than 2,510 square miles. Basin characteristics were updated or created for 248 streamgages. The previously published Oklahoma generalized skew map, a necessary element in the development of the peak-streamflow frequencies was updated. Compared to a previous dataset described in (Lewis, 2010), this dataset incorporates an additional 9 years of annual peak-streamflow data, including 2 years when major peak-streamflows were recorded (2015 and 2017). The additional years of data collection since the publication of Lewis (2010) [...]
Summary
The U.S. Geological Survey (USGS) Oklahoma-Texas Water Science Center, in cooperation with the Oklahoma Department of Transportation, updated basin-characteristic data for Oklahoma streams with drainage areas of less than 2,510 square miles. Basin characteristics were updated or created for 248 streamgages. The previously published Oklahoma generalized skew map, a necessary element in the development of the peak-streamflow frequencies was updated. Compared to a previous dataset described in (Lewis, 2010), this dataset incorporates an additional 9 years of annual peak-streamflow data, including 2 years when major peak-streamflows were recorded (2015 and 2017). The additional years of data collection since the publication of Lewis (2010) also means that several additional streamgages now have an adequate number of years of record for frequency analysis. Some streamgages that provided data for Lewis (2010) have subsequently been determined to be influenced by regulation or were outside of the modified study area and were therefore omitted from this revised dataset. Basin characteristics were determined at each streamgage location by using a geographic information system (GIS) and Bulletin 17B methodology to create an updated Oklahoma generalized skew map. The basin-characteristic data and generalized skew map can be used to asses peak streamflows for unregulated streams in Oklahoma.

Lewis, J.M., Hunter, S.L., and Labriola, L.G., 2019, Methods for estimating the magnitude and frequency of peak streamflows for unregulated streams in Oklahoma developed by using streamflow data through 2017: U.S. Geological Survey Scientific Investigations Report 2019–5143, 39 p., https://doi.org/10.3133/sir20195143.
This data release provides updated dataset of basin characteristics derived from StreamStats and GIS for 248 streamgaging stations in Oklahoma, an updated generalized skew map for Oklahoma, and peak streamflows for unregulated streams in Oklahoma with drainage areas less than 2,510 square miles for 212 streamgages. USGS StreamStats is a web-based tool that allows users to obtain information such as flow statistics, and basin characteristics for user-selected stream locations.
