1 Tifton Georgia Florida Gulf of Mexico Atlanta Athens SE Environmental Flows Conference Roles of Farm Ponds and Potential Impacts on Streams in the Coastal Plain of GA presented by: Jim Hook & Shane Conger National Environmentally Sound Production Agriculture Laboratory The University of Georgia, Tifton Campus

2 Assessment of Farm Ponds  Rationale:

3 Assessment of Farm Ponds Quantity and their hydrologic significance The Study Area: South Georgia HUC08 (Sub-basins)

4 USGS NHD Waterbodies

5 Ga DOT 2003 Waterbodies

6

7 Natural Ponds in the Coastal Plain Landscape  Natural ponds and marshes

8

9 Assessment of Farm Ponds Quantity and their hydrologic significance Study area: South Georgia HUC08 Sub-basins

10 Man-made Ponds in the Coastal Plain Landscape  Man-made ponds and reservoirs

11 Candler Co NHD/DOT Ponds

12 Transects to characterize a sample of study area ponds Random vectors 140 transects km long 0.33 km wide

13 Transects to characterize a sample of study area ponds Any pond w/in or touched by buffered line USGS mapped DOT mapped Visible unmapped

14 Assessment of man-made ponds  Transects

15 Assessment of man-made ponds  Transects

16 Assessment of man-made ponds  String of beads

20 Assessment of man-made ponds  Transects

21 Assessment of man-made ponds  Catchment areas – small to medium

22 Assessment of man-made ponds  Proximity and Use for irrigation <83% within 0.6 km of farm field <64% adjacent to farm field <25% had existing pump or permitted withdrawal present

25 Assessment of man-made ponds  Begin to look at how ponds impact stream flow

26 Assessment of man-made ponds  Begin to look at how ponds impact stream flow

27 Assessment of man-made ponds  Begin to look at how ponds impact stream flow

28 Assessment of man-made ponds  Begin to look at how ponds impact stream flow

29 Assessment of man-made ponds  Plea for inclusion of ponds in models of behavior of watersheds

30 Assessment of man-made ponds  Recommendations
