  3. Why do farmers irrigate? • Reduces risks associated with dry weather (still leaves risks associated with commodity prices) • Stabilizes income • Opportunities for good profits • Opportunity to grow other crops • Vegetable, peanut, early grain contracts • Operational loan (availability, amount) • Land rentals

  4. Why do farmers irrigate? • Land values (collateral, resale, taxes) • Eliminates wasted inputs • Reduces risks of quality loss

  5. Irrigation Decisions create uncertainty • Decision to install/expand irrigation • Can I obtain capital, what risks • Annual Decision on which Lands to irrigate • Do I need to rotate • Annual Decision on which Crops to irrigate • What will be profitable at market time, how cost. • Daily Decisions – to irrigate or not • When, how much – will it pay for itself • Tough economic business decisions • Too many wrong decisions mean economic failure

  6. Decisions about irrigation • A good businessman makes these decisions as part of a well thought out development/ investment plan over a period of years. • Competition requires farmers to used the most efficient use of their combined resources – land, water, equipment, labor, experience.

  7. DNR-EPD Permits all (almost) withdrawals exceeding 100,000 gpd • Since 1988 farmers are required to get a permit from EPD if their pump is capable of pumping > 70 gpm (larger than 4”well). • Ground water withdrawals • Surface withdrawals from streams, canals, ditches, springs, sinkholes, etc. • Surface withdrawals from farm ponds (?) • No reporting requirements • No renewal necessary • No conservation plan required

  8. Restrictions on Permitted Withdrawals 1998-2001 • Freeze on new groundwater withdrawals from Dougherty Plain area of Flint Basin • Freeze on surface water withdrawals from streams everywhere in the Flint Basin • Site visits required by EPD before future permitting. New rules for drillers. • Studies to get accurate acres and irrigation amount. Voluntary - UGA • Flint River Drought Protection Act – evoked March 1, 2001. A 33,000 acreage reduction for 2001.

  9. EPD vs Ext. Survey of Irrigation • Survey during fall 2000 showed the 13 counties had 357,200 acres irrigated that year • EPD has issued permits for a total of 515,100 acres from those counties. • Their freeze on new permits is based on their numbers – to prevent the estimated 100,000 additional requested acres. • Their buyout this year with FRDPA was to eliminate 33,000 surface irrigated acres.
