Karst and the USGS: Seco Sinkhole, Seco Creek, Texas
Detailed Description
Seco Sinkhole is a large karst sinkhole in western Medina County, Texas, where water can be diverted from Seco Creek into the sinkhole. Here, an Edwards Aquifer Authority (EAA) technician measures the flow using an Acoustic Doppler Current Profiler (ADCP) instrument following the Memorial Day floods of 2015. Flow was measured at a rate of 350 cubic feet per second at this time.
