  1. Kansas Transition from Ground Water Development to Enhanced Ground Water Management Define the Resource Beneficial Use Protect and Control Thomas L. Huntzinger, P.E. Kansas Department of Agriculture Division of Water Resources

  2. Water Availability Primary Aquifers

  3. Potential Natural Recharge for the High Plains Aquifer in Kansas

  4. Water – A Public Resource “All water within the state of Kansas is hereby dedicated to the use of the people of the state, subject to the control and regulation of the state in the manner herein prescribed.” K.S.A. 82a-702.(History: L. 1945.)

  5. Water Management K.S.A.82a-705 Acquisition of appropriation right to use water “No person shall have the power or authority to acquire an appropriation right to the use of water for other than domestic use without first obtaining the approval of the chief engineer, … (History: L. 1945; amended 1957.)”

  6. Water Management • Submit an application – obtain priority 2. Approval – is water available, without impairment • Proposed use is reasonable 4. Certification – put to beneficial use Principles of Prior Appropriation First in Time First in Right

  7. Water Management • Priority date 2. Maximum authorized quantity • Maximum rate of diversion • Place of use • Type of use • Location of point(s) of diversion Permits and Water Rights

  8. Water Right Changes • Chief Engineer may approve a change • Must not increase maximum authorized quantity • Must not increase consumptive use • Must not impair other existing rights

  9. Water Management Groundwater Management Districts • Proper management • Conservation • Prevent economic deterioration • Stabilize agriculture K.S.A. 82a-1020 Western Kansas GMD #1 Southwest Kansas GMD #3 Northwest Kansas GMD #4 #4 Equus Beds GMD #2 Big Bend GMD #5 #1 #2 #5 #3

  10. Water Management Intensive Groundwater Use Control Areas IGUCA • Unique management approach • Declining water levels • Withdrawal exceeds recharge • Preventable waste • Other requirements

  11. Water Management Closed and Restricted Areas

  12. KANSAS WATER PLANNING KANSAS WATER AUTHORITY • Chairman Appointed by Governor • Voting Members • Water Interest Groups • Legislative Appointees • Ex-Officio – Non-Voting Members • State Water Agency Heads

  13. KANSAS WATER PLAN • Kansas Water Office prepares plans in coordination with state water agencies. • Plan Approved by the Water Authority. • Plan recommends policies to Governor and Legislature.

  14. HIGH PLAINS WATER MANAGEMENT • Advisory Committee of Water Users • Convened: Director of the Kansas Water Office • Chairman: Irrigation Farmer • Charge: Recommend Strategy to Address Depletion

  15. RECOMMENDATIONS Protocols – Groundwater Management Districts Lead Define Hydrologic Subunits Approved by Division of Water Resources Data at Square Mile Scale

  16. Priority Aquifer Subunits Defined by Projected Useful Lifetime & Water Use Density within Southwest Kansas Water Management District #3

  17. RECOMMENDATIONS Concepts – Projected Useful Life Water Use Density Threshold Pumping Rates Identify Priority Subunits Results at Township Scale

  18. RECOMMENDATIONS Implementation Incentive-Based Programs Buyout/Water Right Retirement Cost Share in Transition to Dryland Follow Kansas Water Law Regulatory Options Increased Compliance Enforcement

  19. Appropriation of WaterK.S.A. 82a-711 and 711a Neither impairs an existing right Unreasonable lowering of water table Beyond a reasonable economic limit Nor unreasonably affects the public interest Safe yield Priority Amount of each claim to use water Economics for existing water users Existing rights can be satisfied

  20. Walnut Creek IGUCA Allocation Equal Safe Yield Allocated by Priority in % of Authorized Vested Rights – 100% Appropriations prior to Safe Yield (1967) – 60% Appropriations after 1967 – 40%

  21. Two Mile Circle • Authorized Quantity in 2 Mile Circle:  8611 AF • Authorized Quantity for File Number 10,497:  310 AF • Authorized Quantity for File Number 11,024:  200 AF • Estimated Potential Annual Recharge:  0.5 inches • Safe Yield Quantity for 2 Mile Circle:  251.33 AF

  22. Dryland Sorghum

  23. Total Decadal Precipitation Deficit from Selected Seasonal Precipitation Selected Seasonal Precipitation Decade 8 inches 9 inches 10 inches 1950 thru 59 3.52 6.55 10.55 1960 thru 69 0.04 1.04 2.04 1970 thru 79 0.53 1.53 2.8 1980 thru 89 6.45 8.45 11.11 1990 thru 99 0.51 1.51 2.51 Estimated recharge per decade is 5 to 10 inches.
