Data are available as a Google Map with links to Station Information and Data for each site. Data are available for 58 sites along I-75 and for 28 sites along State Road 29 in Big Cypress National Preserve. Data collected in this project will provide baseline information about a major current barrier to sheetflow, I-75. The data are expected to support the research on the existing linkages among geologic, hydrologic, chemical, climatological, and biological processes that currently shape the Everglades and will provide insight into the predrainage Everglades. The baseline flow will contribute to the Southwest Florida Feasibility Study addressing the health of upland and aquatic ecosystems in the 4,300 square mile area. 200511 200909 ground condition In Work As needed -81.325 -80.75 26.25 25.75 none sheetflow surface water discharge stage velocity hydrology ISO 19115 Topic Category environment inlandWaters 007 012 Department of Commerce, 1995, Countries, Dependencies, Areas of Special Sovereignty, and Their Principal Administrative Divisions, Federal Information Processing Standard (FIPS) 10-4, Washington, DC, National Institute of Standards and Technology United States US U.S. Department of Commerce, 1987, Codes for the identification of the States, the District of Columbia and the outlying areas of the United States, and associated areas (Federal Information Processing Standard 5-2): Washington, DC, NIST Florida FL Department of Commerce, 1990, Counties and Equivalent Entities of the United States, Its Possessions, and Associated Areas, FIPS 6-3, Washington, DC, National Institute of Standards and Technology Collier County USGS Geographic Names Information System Big Cypress National Preserve Barron River Everglades City none SW Big Cypress Interstate 75 State Road 29 none none Rick Solis U.S. Geological Survey mailing and physical address

Collate this information together with available GIS coverages for development of a plan to coordinate future flow measurement team deployment for both boundaries of the study area. 2006 Discharge measurements Reconnaissance of each bridge, culvert and wildlife through-way for appropriate measurement locations and methods. This includes documentation of weed conditions affecting periodic flow shifting, water depth, and establishment of reference marks to do distance to water measurements for indications of significant east-west flow "short-circuting". Discharge at each bridge, culvert and wildlife throughway will be measured in one day. Stream-flow measurements will be accomplished by Price AA meter, flow rods, or acoustic doppler point and/or profiling velocity meters as conditions at the controls allow. As of the end of September, 2006 four synoptic discharge measurements have been accomplished in the I-75 corridor from the L-28 Interceptor Canal to SR 29 and SR 29 from I-75 south to USGS site 02291000 Barron River near Everglades, FL. Initial evaluation determined the need to move one culvert index site scheduled for August 31, 2006 2006 Placement of stage and index gages Three index-velocity gages have been installed inside culverts running under I-75 and an additioal one may be installed in WY 2007. These gages collected stage and velocity data every 15 minutes, Additional measurements have been made at these culverts for discharge verification. 2007 Data collection and feasibility of study continuation The development of a discharge relationship is directly related to the DOI Science plan by giving a continuous record of discharge into Big Cypress National Preserve. If a relationship can not be determined, specific recommendations will be prepared concerning the best methodology. In order to ensure the instrumentation is working well, data will be downloaded once a month as well performing a discharge measurement just at that particular culvert. Not complete Tying in bridge reference marks to existing benchmarks DOT benchmark placement close to the bridges will be researched. A team of personnel will then go and field-truth the placement of the benchmarks to assess the feasibility of running a set of optical levels from the benchmark to a predetermined reference mark on the bridge. These bridge reference marks will be fully documented and the information will be provided to Big Cypress personnel. Reference marks that are tied into existing benchmarks will lead to water level measurements at specific bridges that are tied to the same datum plane. Not complete The index-velocity meters are operating and discharge measurements are being made to develop the index-velocity to discharge relationship. Evaluation of the discharge measurements made has shown the need for fewer measurements during the dry periods. This has resulted in clustering more of the measurements during the summer months than making measurements on a strict quarterly basis. 2007 Placement of existing and future gages behind the I-75 fence to address safety concerns. This task is to work with the Florida DOT and their respective contractors to put gates in the existing fences so that the equipment that is currently located in the median of I-75 can be moved inside the fence. This will allow the potential to telemeter these sites in the future so conditions can be easily monitored. Not complete Rick Solis U.S. Geological Survey mailing and physical address
