USGS Water-Year Summary 2024
0204295063 STORM DRAIN AT LINDSLEY DRIVE NEAR VIRGINIA BEACH, VA
LOCATION - Lat 36°51'28.90", long 76°01'19.90" referenced to North American Datum of 1983, Virginia Beach City, VA, Hydrologic Unit 02080108,
DRAINAGE AREA - 51.1 acres
REVISIONS HISTORY - The approved specific conductance timeseries beginning on the first day of the period of record and ending on 2/14/2019 was temporarily set to provisional (working) on 7/31/2019 to remove many spikes previously retained. These spikes were thought to be representative of changing conditions; however, additional reconnaissance determined that these spikes were in response to salamanders swimming into the conductance port on the YSI 600 OMS meter. a fine mesh screen has since been placed over the port to prevent this issue going forwards. Following removal of erroneous points the period was reset to approved.
