Outline• What is the economic impact of agriculture to the
Lower Flint River Basin and SW GA as a whole?– Farm gate, direct and indirect output/employment
• What are the potential impacts of reducing irrigated acreage in Spring Creek and Ichaway sub-basins?– Scenarios from EPD planning documents– Assumptions
• Irrigation and yield data– Basin and region level
• Farm level impacts of reducing irrigation• Recent advances in knowledge base regarding
agricultural water use • Discussion

So what is the regional impact of irrigation?
![Page 8: Mark H. Masters ASU Flint River Water Policy Center](https://reader036.vdocuments.net/reader036/viewer/2022062410/56815980550346895dc6bf19/html5/thumbnails/8.jpg)
• Concentration of modeling efforts in Ichaway and Spring Creek Sub-basins.
• EPD surface water models indicate low-flow violations under some conditions– Especially Spring Crk
• 326,204 permitted irrigated acres in these two basins – 153,263 (Ichaway)– 172,941 (Spring)– ≈ 62% of harvested land
![Page 9: Mark H. Masters ASU Flint River Water Policy Center](https://reader036.vdocuments.net/reader036/viewer/2022062410/56815980550346895dc6bf19/html5/thumbnails/9.jpg)
• This analysis was limited to all surface water w/drawals and those ground water w/drawals out of the Upper Floridan as determined by EPD
• This amounts to roughly 241,000 irrigated acres– 100,890 in Ichaway– 140,130 in Spring
• Ichaway region includes Terrell, Randolph, Calhoun, and Baker Counties
• Spring Creek region includes Early, Miller, Seminole, and Decatur counties
![Page 10: Mark H. Masters ASU Flint River Water Policy Center](https://reader036.vdocuments.net/reader036/viewer/2022062410/56815980550346895dc6bf19/html5/thumbnails/10.jpg)
Impact Model• IMPLAN
– IMpact analysis for PLANning– Input–Output model describing commodity
flows from producers to final consumers– Driven by purchases for final use or final
demand (in our case, lost revenue from not irrigating)
• Direct effects• Indirect Effects
– Multipliers
– Region specific• Base model (2006) or modified

Flint River Drought
Protection Act • Inaugural auction held March
15, 2001– 33,101 acres retired from
irrigated production– Average bid: $136/acre– $4.5 million paid to growers
• Auction held again in 2002– 40,894 acres retired– Average bid: $128/acre– $5.2 million paid to growers
• Major changes for Act after Flint River Water Dev. and Conservation Plan passed March 2006

Illustrative Purposes Only – Of the 10,356 acres within 3 miles of a stream and in Capacity Use Areas, 91% are “Grandfathered” Permits. It is extremely likely these areas could be impacted by a Flint River Drought Auction with economic impacts highly localized.

Moving Forward
• We are better positioned to plan for agricultural water use …kind of– Data collection (revised models)– Outreach– Interaction and compilation of programs– Statutes
• Conservation– Acceptance of irrigation scheduling, conservation
tillage and system upgrade programs– Built-in conservation in the form of energy prices
• Participation in planning process
