Aquifer Storage and Recovery: A Practical Training Workshop Implementation of Public and Private Managed Aquifer Recharge in Idaho Managed Aquifer Recharge in Idaho David R. Tuthill, Jr., Ph.D., P.E. August 19, 2015
Outline Idaho and many other Western States recognize a connection between surface water and ground water First in time is first in right Water right adjudication enables joint (conjunctive) administration Continuation of pumping junior wells requires mitigation Ground water recharge via Managed Aquifer Recharge can be a solution
In Idaho the appropriation doctrine is used for the delivery both surface water rights and ground water rights— “first in time is first in right”
Problem Water deliveries must consider connections between ground water and surface water (conjunctive administration) if fair delivery is to be achieved if fair delivery is to be achieved

Steps Toward Conjunctive Administration in the Wood River Valley Adjudicate the surface water rights ~ 1900 Establish Water District 37 to administer surface water rights ~ 1900 Commence delivery of surface water rights ~ 1900 Commence delivery of surface water rights ~ 1900 Adjudicate ground water rights – 1987 – 2013 Establish a Water Measurement District -- 2011 Incorporate ground water rights in Water District 37 – 2013 Construct a ground water model – 2015 “Delivery Call” from senior water rights -- 2015 Commence delivery of ground water rights – 2016 likely
So…. What is the solution? To the extent there is an available water supply, implement water supply, implement Managed Aquifer Recharge

What entities will develop storage and recharge in the future? Public-Private Partnerships Irrigation Districts, Private Canal Companies, Canal Companies, Development Development Municipalities Company • Expertise Local, State and • Expertise • Facilities • Funding Federal • Storage Water • Techniques • Regulatory Government • Administration preferences • Expertise • Initiative • Regulations • Oversight • Funding • Enforcement
Managed Aquifer Recharge Public Public Private Private Public-Private Public-Private Partnership Recharge Recharge • Combined benefits • Raise water levels • Mitigation for existing uses • Hard to achieve • Increase supply • Water for new uses • Reduce delivery calls
Three Approaches Approach 1 – State pays canal companies to recharge using state water rights. Approach 2 – State partners with private Approach 2 – State partners with private companies to incentivize recharge under private companies to incentivize recharge under private rights – the state pays less, and receives its return via uncaptured recharge. This offers the potential for a large return on investment for the state. Approach 3 – Municipality partners with private companies to incentivize recharge under private rights.

Implementation of Public Private Partnerships Will Stimulate Managed Aquifer Recharge in Idaho
Next Step The time is right for public and private entities to move forward to implement Managed Aquifer Recharge opportunities – Managed Aquifer Recharge opportunities – before delivery calls are made
