The FDEP Watershed Network The FDEP Watershed Network Volume 1, Issue 2 – Summer 2008 In this issue: Links to more information: Chief’s Chatter Background Hot News • TMDL Program Overview Featured articles • TMDL Program Personnel updates • Basin 411 Coming Events • Impaired Surface Waters Rule • FAQs • Status & Assessment Reports • TMDL Reports Chief’s Chatter – Eric Livingston, Bureau Chief We appreciate the positive feedback we received on the first edition of the Bureau of Watershed Management’s newsletter. We are glad that it is helping our staff and stakeholders keep up with all of the activities ongoing within our TMDL/watershed restoration program. A lot has happened during the last three months and hopefully this edition of the Newsletter will get you caught up with the action! You will find information on the adoption of the first TMDLs for springs, the most recently adopted Basin Management Action Plans, water program reorganization, and more. We welcome feedback from our watershed stakeholders and invite them to provide articles for future Newsletters. Hot News First Springs TMDL Adopted In 2004, the Florida Legislature passed the Wekiva Parkway and Protection Act (WPPA) (Chapter 369, Part III, FS), which required the the St. Johns River Water Management District to establish pollutant load reduction goals for the Wekiva Study Area to assist the DEP in adoptingTMDLs for impaired waters within the Wekiva Study Area. The impaired waters include nutrient impairments in the Wekiva River (including Wekiwa Spring), Rock Springs Run, Spring Lake, Lake Florida, Lake Orienta, Lake Adalaide, Lake Lawne, Silver Lake, and Bay Lake, nutrient and dissolved oxygen impairments in the Little Wekiva Canal, and fecal coliform impairment in the Little Wekiva Canal and the Little Wekiva River. Since the science on healthy nutrient levels in springs is not as refined as the science for lakes or rivers, scientists from the SJRWMD and DEP worked collaboratively on the science of deriving a nutrient TMDL for springs. They examined several lines of evidence between nutrient concentrations and the growth of algae to derive the TMDL. The target nitrate concentration for the Wekiva River and Rock Springs Run was established based 1) laboratory nutrient amendment bioassays, 2) examining the relationship between periphyton biomass and cell density and the nitrate concentration in flow- through systems similar to the Wekiva River and Rock Springs Run, and 3) comparing metabolic rates, specifically, ecological efficiency, of aquatic communities in the Wekiva River and Rock Springs Run with those in reference creeks. Based on information from these lines of evidence, the TMDL was established as a concentration of,286 µg/L nitrate as the target concentration that will not cause an imbalance in the aquatic flora and fauna in the Wekiva River and Rock Springs Run. The total phosphorus target (TP) for the Wekiva River and Rock Springs Run was established based on the studies on the attached algal communities conducted by the GreenWater Labs (2005) and the ecosystem metabolism studies conducted by the Wetland Solution, Inc. (2005). Based on these studies, a TP concentration of 65 µg/L was chosen as the final TMDL. Orange Creek BMAP Adoption On May 15, the Florida Department of Environmental Protection (DEP) adopted by Secretarial Order the Orange Creek Basin Management Action Plan (BMAP), a roadmap to restoring and protecting water quality in the Orange Creek Basin. The action plan, developed in partnership with the City of Gainesville, Marion and Alachua Counties, the St. Johns River Water Management District, Alachua County Health Department, University of Florida, Gainesville Regional Utilities, private silviculture interests and other local and state stakeholders. Orange Creek is a tributary of the Ocklawaha River. Implementation of the plan will benefit surface waters in Alachua and Marion Counties, including Orange Lake, Lochloosa Lake, Newnans Lake, Tumblin Creek, Sweetwater Branch, Hogtown Creek, Lake Wauberg, Paynes Prairie/Alachua Sink, and the Ocklawaha River. Through a science-based program, DEP determined that seven of the waterbodies in the Orange Creek Basin did not meet Florida’s water quality standards and needed action plans. High levels of nutrients in the lakes caused an imbalance in the native plant, fish and wildlife communities. Furthermore, high levels of fecal coliform bacteria in the creeks were in violation of state water quality standards. In 2003, DEP adopted water quality restoration targets, called Total Maximum Daily Loads (TMDLs) for these impaired waters. The TMDLs establish the amount of reduction of nutrients that is needed to protect or restore the lakes and Alachua Sink, and the amount of reduction of fecal coliform bacteria that is needed to protect or restore streams in the basin. The TMDLs help stakeholders evaluate and identify local actions to control these pollutant discharges. The action plan lists the steps that must be taken, a schedule for their implementation, and potential resources to accomplish them. “The Orange Creek Basin Management Action Plan represents an exceptionally strong collaboration among local, regional, and state agencies, elected officials, citizens, and private interests,” said DEP Deputy Secretary Mimi Drew. “Together we have committed to a concrete set of actions to reduce pollution in the streams, rivers, and lakes throughout the basin.” Actions called for in the BMAP include better identification and remediation of sources of fecal coliform in creeks and nutrient discharges to lakes and Alachua Sink, continued improvement in stormwater treatment and control programs, better stormwater controls for active agricultural and commercial forest lands, more stringent local ordinances to control pollution, and an ongoing program of public and private education. Long Branch BMAP Adoption On May 15, the Florida Department of Environmental Protection (DEP) adopted by Secretarial Order the Long Branch Basin Management Action Plan (BMAP). The action plan, developed in partnership with Orange County and the Florida Department of Agriculture and Consumer Services, identifies actions that are needed to decrease bacteria and nutrients in Long Branch. The Long Branch BMAP was developed under DEP’s comprehensive approach that builds partnerships with local, regional and state interests to identify and restore polluted waterbodies. Long Branch is a tributary of the Econlockhatchee River in unincorporated Orange County, between Bithlo and Wedgefield. Implementation of the plan will benefit water quality in the Long Branch mainstem and tributaries. Using the Impaired Waters Rule methodology, DEP determined that Long Branch did not meet Florida’s water quality standards and needed an action plan. High levels of nutrients in the stream caused an imbalance in the native plant, fish and wildlife communities. In addition, high levels of fecal coliform bacteria in the creeks were in violation of state water quality standards. In 2006, the DEP adopted water quality restoration targets, called Total Maximum Daily Loads (TMDLs) for Long Branch. The TMDLs establish the amount of reduction of nutrients and the amount of reduction of fecal coliform bacteria that is needed to protect or restore Long Branch. Actions called for include improvements in stormwater management, implementation of agricultural best management practices, field investigations to better identify pollutant sources and ongoing public education programs. The Orange County Environmental Protection Division has already completed a number of these actions. Additional work as set forth in the BMAP will be conducted during the next few years. Group 1 Verified List adoption and TMDL Development The Cycle 2, Group 1 Verified List and Delist List were adopted by Secretary Sole in early June as we were going to press. TMDLs for the Group 1 waters that are required this year by the TMDL Consent Decree are being developed and will be posted on the TMDL web site on June 20. Public meetings on the TMDLs will be held during July with adoption to occur prior to September 1. This will assure that EPA will not have to propose the TMDLs on September 30 as required by the Consent Decree. Group 2 Verified List Coming Soon We are working on the draft Verified List and Delist List for the Group 2 waters as we go to press. We hope to publish these on the web in early July, conduct public meetings in July and August, and develop a revised list for public review in September or October. Stay tuned!

  • Northwest Florida Water Management District Hydrologic Conditions
    Northwest Florida Water Management District Hydrologic Conditions Update July 2018 – December 2018 April 1, 2019 Executive Summary Cumulative average rainfall for the last six months was well above normal for the District. After experiencing a wetter-than-normal spring and early summer, significant amounts of rainfall during the second half of the 2018 calendar year resulted in high groundwater recharge and very high streamflow. Rivers and streams of the District are generally in the well above normal to high flow levels. Precipitation Summary Rainfall totals, compared to current National Weather Service Climate Normals (1981-2010 reference period), from July to December were above normal across the District at 49.33 inches (normal cumulative rainfall for this period is 31.04 inches). Rainfall in July was 8 percent above normal at 7.69 inches. August rainfall totals were 57 percent above normal at 10.28 inches. September rainfall totals were 38 percent above normal at 7.48 inches. Rainfall in October was 37 percent above normal at 5.00 inches. Rainfall in November was 57 percent above normal at 6.61 inches. Rainfall totals in December were 200 percent above normal at 12.27 inches. Significant Events Heavy Rainfall and Minor Riverine Flooding – August 01-03, 2018 Heavy rainfall was observed after a frontal system passed across the Panhandle.
