Location of study area and Pee Dee NWR in North Carolina

As part of the study, stage was continuously measured at one site on Brown Creek and two sites on the Pee Dee River. Partial records of stage were recorded for high-flow conditions at two additional sites on Brown Creek, one site on Thoroughfare Creek and one additional site on the Pee Dee River. Existing USGS streamgages on the Pee Dee River directly downstream of Lake Tillery and on the Rocky River near Norwood, NC were also utilized in the study. Data from all of these sites were used for model development and calibration.

¹ Period of record for partial-record sites indicates the dates equipment was installed and removed for this project. These stations were used to record high-flow conditions only, so there are limited recorded data points at each station. Data will be published in the final report.

² Station 02127422, Brown Creek at Bennett Bridge near Ansonville, had been operated as a partial record station prior to this project. Periodic discharge measurements made at this site from 1985 to 1995 were used in model development and calibration.
