Study Title: Surface-Water Flow Through the Tamiami Trail within the Greater Everglades
Study Start Date: 1949 Study End Date: ongoing
Web Site: http://sofia.usgs.gov/projects/surf_wtr_flow/
Location (Subregions, Counties, Park or Refuge): Miami-Dade and Collier Counties along US Hwy 41.
Funding Source: USGS Greater Everglades Priority Ecosystems Science (GE PES); U.S Army Corps of Engineers, Department of Interior Modwaters program
Other Complementary Funding Source(s): U.S. Army Corps of Engineers (services in-kind)
Funding History: FY49 -- FY11
Principal Investigator: Mark Dickman
Study Personnel: Mark Dickman, mdickman@usgs.gov, Carolyn Price, eprice@usgs.gov, and various other Florida Water Science Center staff.
Supporting Organizations: U.S Army Corps of Engineers, Department of Interior Modwaters program, South Florida Water Management (SFWMD), Everglades National Park.
Associated/Linked Projects: Coastal Gradients among many, many others.

Overview & Objectives:

The project will continue flow measurements, water level data collection, rating refinement and calibration of the discharge ratings at the three culvert and bridge stations and the 4 gated structures to produce continuous records of water levels and flow through the Tamiami Trail into the Big Cypress Preserve and the Everglades National Park. Provisional discharge measurements and data record will continue to be analyzed, processed and forwarded to the USACE and ENP for evaluation of the effects of structure operations on flows into the Everglades National Park and Big Cypress National Preserve. Final quality assured water-level and flow to be published in the publication Water-Data Report 2012 and available on NWISWeb. Two stations include instrumentation for telemetry of the real-time data to NWISWeb for real-time public release, and one station will be updated to real-time telemetry pending approval.

Specific Relevance to Major Unanswered Questions and Information Needs Identified:

The Tamiami Trail series of measurement sections and gages are the only long term monitoring of flows across the entire width of the Everglades. Flow monitoring is critical to understanding the flows through the Everglades and into the Everglades National Park and Big Cypress Preserve which is a primary goal of the Comprehensive Everglades Restoration Plan (CERP) and the Greater Everglades Priority Ecosystem Science program (GE PES). The data record covers a long time period which is an important aspect of understanding the flow quantities and distributions within the Everglades and to Shark River Slough and Lostmans Slough, the major flow ways to the estuaries. Ongoing and planned projects, such as the Modified Water Deliveries, the Tamiami Trail Bridge Modifications Project and the Decompartmentalization project, among many others, require these data sets in order to adequately evaluate the effects of restoration efforts on flow quantities, timing, and distribution.

Finally this study supports the Ecosystem Restoration mission delineated in the Five Year Science Plan for the Florida Water Science Center.

Status:

Provisional analysis and computation of 2011 water year flow data continues along with ongoing flow measurement, water level recording, and rating calibration for all seven stations. Pre-publication data sets continue to be transferred to USACE and ENP support staff for ongoing, real-time evaluations of flows through the Tamiami Trail section. Two stations were recently updated to real-time telemetry with the third pending approval.

Recent Products: (Water-Data Report 2010).

Planned Products: Real-time and daily value data on NWISWeb, Water-Data Report 2011, and Water-Data Report 2012.

Task Summary and Objectives:
The project will continue flow measurements, water level data collection, rating refinement and calibration of the discharge ratings at the three culvert and bridge stations and the 4 gated structures to produce continuous record of flow through the Tamiami Trail into the Big Cypress Preserve and the Everglades National Park. Two stations were recently updated with telemetry for real-time public release of the provisional data and the third station is pending approval before telemetry will be installed. Provisional discharge measurement, water level data and continuous flow data will continue to be analyzed, processed and forwarded to the USACE and ENP for evaluating the effects of structure operations on flows into the Everglades National Park and Big Cypress National Preserve. Final quality assured water-level and flow to be published in the publication Water-Data Report 2012 and NWISWeb.

Work to be undertaken during the proposal year and a description of the methods and procedures:

FY12:

  1. Continue measuring flows, recording continuous water levels, and rating calibration of the discharge ratings at the three culvert stations throughout the range of flow conditions, hydro-periods, and structure operations to produce continuous discharge record.
  2. Continue measuring flows, recording continuous water levels, and rating calibration of the discharge ratings at the four gated S-12 stations (A-D) throughout the range of flow conditions, hydro-periods, and structure operations to produce continuous discharge record.
  3. Two stations updated with telemetry for the public release of real-time data. The last station is pending approval.
  4. Provide provisional real-time and historical daily mean data on NWISWeb.
  5. Data quality assurance reviews will continue throughout the water year culminating in the publication of daily mean water levels and discharge for these sites in the USGS report entitled, Water-Data Report 2012. Efforts to provide information to appropriate electronic outlets will continue.

Specific Task Products(s): Provisional real-time and daily mean stage and discharge data will be made through NWISWeb; finalized stage and discharge data published in the "Water-Data Report 2012."
