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.)
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.)”
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
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
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
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
Water Management Intensive Groundwater Use Control Areas IGUCA • Unique management approach • Declining water levels • Withdrawal exceeds recharge • Preventable waste • Other requirements
Water Management Closed and Restricted Areas

RECOMMENDATIONS Protocols – Groundwater Management Districts Lead Define Hydrologic Subunits Approved by Division of Water Resources Data at Square Mile Scale
Priority Aquifer Subunits Defined by Projected Useful Lifetime & Water Use Density within Southwest Kansas Water Management District #3
RECOMMENDATIONS Concepts – Projected Useful Life Water Use Density Threshold Pumping Rates Identify Priority Subunits Results at Township Scale
RECOMMENDATIONS Implementation Incentive-Based Programs Buyout/Water Right Retirement Cost Share in Transition to Dryland Follow Kansas Water Law Regulatory Options Increased Compliance Enforcement
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
