Data collection occurred at all culverts between culvert 22 near Royal Palm access road and culvert 160 near West Lake on November 17, 2004, August 10, 2005, and September 27, 2005,

Year 2 included data from June 2005 through the last period of satisfactory data before the water level at the sensor was lower then the minimum depth required for sampling, equipment malfunction or December 31, 2005. Data recorded after December 31, 2005, were removed due to the lack of field visits to assure data accuracy.
Data were collected at 7 culverts (30, 34, 43, 59, 77, 89, and 108) along SR 9336 in 2004-2005.
Compilation and summation of four geographic segments of SR 9336 were achieved through computation of the culvert flow discharges for each intensive field effort. The four segment summations are: (1) culvert 22 near Royal Palm Road to culvert 42 near the access road for Pa-hay-okee Overlook; (2) culvert 43 near the access road for Pa-hay-okee Overlook to culvert 63 near the access road for Mahogany Hammock; (3) culvert 64 near the access road for Mahogany Hammock to culvert 110 near Nine Mile Pond; and (4) culvert 111 near Nine Mile Pond to culvert 155 near West Lake. A fifth geographic segment represented the area from the ENP entrance to culvert 22. Similar road segment delineations and culvert groupings are described in a previous USGS study of culvert flows measured in 1997 and 1998 (Tillis, 2001). Personnel from the ENP Research Center computed and provided flow discharge between the ENP entrance and culvert 22 near Royal Palm Road. Flows through culverts south of Nine Mile Pond near culvert 111 were not measured in the previous USGS study (Tillis, 2001), and flows through culverts south of West Lake (south of culvert 155) were not measured in this study.
See USGS Data Series 358 (<http://pubs.usgs.gov/ds/358/>) for a more detailed explanation of the instrumentation and data collection techniques.
Surface water data consisting of collection date and time, water depth culvert in meters, average velocity in centimeters per second, velocity_cell1, velocity_cell2, and estimated discharge in cubic meters per second were collected at culverts 30, 34, 43, and 59. Water level data for culvert 77 consisting of date and time and water level east in meters (equipment within 15 feet of SR9336 and the culvert on the east side of SR9336) and water level west (equipment within 15 feet of SR9336 and the culvert on the west side of SR9336) in 2004 and 2005.
ADV data are available for culverts 77, 89, and 108. The data consist of date and time of collection, east velocity in centimeters per second, west veolcity in centimeters per second, speed in centimeters per second, direction in degrees, water temperature in deg C, salinity in parts per thousand, conductivity in microsiemens per centimeter, and velocity in centimeters per second.
Data collected for culverts 22-160 include: depth, salinity, velocity, discharge, and field notes on three separate dates.
