Abstract:

This data publication contains streamflow, water chemistry, water table and weather data measured at the Watershed 77 (WS77) on the Santee Experimental Forest near Cordesville, South Carolina from 1964 to 2022. The major treatments imposed on this watershed over its history have been forest thinning and prescribed fire. Watershed 77 also suffered major damage during Hurricane Hugo in September 1989 (as did the control Watershed 80), which is reflected in the measurement periods. Daily streamflow records are provided from 1964-1981, November 1989-2000, and 2003-2022 as well as 10- or 15-minute streamflow from 2003-2022. Approximately weekly water chemistry samples were collected upstream of the Watershed 77 weir from 1976-1982 and 1989-1994. From 2003-2022 stream water samples were collected during periods of active flow by an automated sampler on a flow-proportional basis, and starting in 2006 additional water quality parameters were measured in situ on an approximately weekly basis. Well water levels were monitored manually approximately every two weeks from 1964-1971 (in a network of 24 non-recording wells) and 1992-1995 (in a network of 42 non-recording wells) on Watershed 77. Hourly well water levels were electronically recorded from 2005-2022. Daily precipitation was recorded manually from 1963-1984 at five different gauges near WS77. Daily precipitation was recorded manually at the Met 5 station from 1963-1966 and electronically from 1989-1997. Daily temperatures were recorded at the Met 5 station from 1996-2000. From September 2001 through 2022 hourly air temperature, soil temperature, and rainfall were recorded at the Met 5 station. In 2020 a major new, long-term project was initiated to convert most of the watershed area from an existing loblolly pine to a longleaf pine dominated system. Harvesting operations in each of three treatment areas (Regeneration, Group Selection, and Thinning) began in April 2020 and continued, with lengthy delays resulting from wet site conditions, until November 2021. An initial site preparation prescribed burn was conducted on March 13, 2022.
