  • 2017 Altamaha Regional Water Plan
    2017 REGIONAL WATER PLAN ALTAMAHA REGION BACKGROUND The Altamaha Regional Water Plan was initially completed in 2011 and subsequently updated in 2017. The plan outlines near-term and long-term Counties: Appling, Bleckley, strategies to meet water needs through 2050. The Altamaha River, formed Candler, Dodge, Emanuel, by the confluence of the Ocmulgee and Oconee Rivers, is the major surface Evans, Jeff Davis, Johnson, water feature in the region. The Altamaha Region encompasses several Montgomery, Tattnall, Telfair, Toombs, Treutlen, Wayne, major population centers including Vidalia, Jesup, Swainsboro, Eastman, Wheeler, Wilcox and Glennville. OVERVIEW OF ALTAMAHA REGION The Altamaha Region includes 16 counties in the south central portion of Georgia. Over the next 35 years, the population of the region is projected to increase from approximately 256,000 to 285,000 residents. Key economic drivers in the region include agriculture, forestry, professional and business services, education, healthcare, manufacturing, public administration, fishing and hunting, and construction. KEY WATER RESOURCE ISSUES Groundwater (the majority from the Floridan aquifer) is forecasted to meet about 70% ADDRESSED BY THE COUNCIL of the water supply needs, with agricultural and industrial uses being the dominant 1. Current and future groundwater demand sectors. Surface water is utilized to meet about 30% of the forecasted water supplies for municipal/domestic, supply needs, with agriculture and energy as the dominant demand sectors. The industrial and agricultural water use energy sector is a major user of surface water from the Altamaha River. 2. Sufficient surface water quantity and quality to accommodate current and ALTAMAHA future surface water demands WATER 3.

  • STURGEON HABITAT QUANTIFIED by SIDE-SCAN SONAR IMAGERY By
    STURGEON HABITAT QUANTIFIED BY SIDE-SCAN SONAR IMAGERY by JOHN DAVID HOOK (Under the Direction of Nathan P. Nibbelink and Douglas L. Peterson) ABSTRACT The assessment and monitoring of freshwater habitats is essential to the successful management of imperiled fishes. Recent introduction of recreational multi-beam and side-scan sonar equipment allows rapid, low cost acquisition of bathymetric data and substrate imagery in navigable waters. However, utilization of this data is hindered by a lack of established protocols for processing and classification. I surveyed 298 km of the Ogeechee River, Georgia using low-cost recreational-grade side-scan and bathymetric sonar. I assessed classification accuracy of three approaches to working with recreational- grade sonar and quantified potential spawning grounds for Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus). I demonstrate that ecologically relevant habitat variables can be derived from low-cost sonar imagery at low levels of processing effort. INDEX WORDS: Side-scan sonar, Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus), habitat, classification accuracy STURGEON HABITAT QUANTIFIED BY SIDE-SCAN SONAR IMAGERY by JOHN DAVID HOOK B.S., Cleveland State University, 2008 A Thesis Submitted to the Graduate Faculty of The University of Georgia in Partial Fulfillment of the Requirements for the Degree MASTER OF SCIENCE ATHENS, GEORGIA 2011 © 2011 John David Hook All Rights Reserved STURGEON HABITAT QUANTIFIED BY SIDE-SCAN SONAR IMAGERY By JOHN DAVID HOOK Major Professors: Nathan Nibbelink Douglas Peterson Committee: Jeffrey Hepinstall-Cymerman Thomas Jordan Electronic Version Approved: Maureen Grasso Dean of the Graduate School The University of Georgia December 201 iv DEDICATION I would like to dedicate this to my parents, John and Joyce, whose continued support, encouragement, and enthusiasm have made all my endeavors possible, and to Emily, whose love and patience seem to know no bounds.

    POTENTIAL THREATS OF THE EXOTIC APPLE SNAIL POMACEA INSULARUM TO AQUATIC ECOSYSTEMS IN GEORGIA AND FLORIDA by SHELLEY MARIE ROBERTSON (Under the Direction of Susan Bennett Wilde) ABSTRACT The Island apple snail, Pomacea insularum is a freshwater gastropod in the family Ampullaridae. It was introduced into the United States via the aquarium trade approximately 30 years ago and now has established reproducing populations in at least seven southeastern states. It is a highly invasive species with high rates of reproduction and consumption of native aquatic vegetation. A survey of reported Georgia populations confirmed that there are at least ten individual occurrences of exotic apple snails in the state, and that they have not reached their equilibrium distribution. We also investigated the ability of P. insularum to harbor a cyanotoxin that may be detrimental to its avian predator in Florida, the endangered Florida snail kite (Rostrhamus sociabilis). The invasive P. insularum transferred the undescribed cyanotoxin associated with Avian Vacuolar Myelinopathy to domestic chickens in a laboratory feeding study.
