Capacitance rod installed in Weir 4 stilling pool, located in watershed 4, midway between USFS road 325 (top of hillslope) and Holcombe's Branch. Measuring Discharge/Runoff via stage (5 min resolution) in stilling pool of 90 degree v-notch weir and USFS rating curve: Q = 2.48*(h(ft))^2.49; Q = discharge in cfs, h = stage in feet. Discharge data converted to L/s. Runoff data, in mm/hr, calculated by normalizing discharge to watershed 4 area (6.9 ha). Capacitance water level meter is TruTrack, WT-HR 1000, manually donwloaded every six weeks.

    A fantastic data set! I have visited the Calhoun CZO, specifically Watershed 4 and was very impressed by Jon's work to up-instrument weirs first installed many years ago by the Forst Service. I have used these data as part of my own cross-CZO network research. Thank you!
