Eastern Snake River Plain Aquifer

Conjunctive Management Rules,Supreme Court decision.

ESPA Comprehensive Planning Process. 2007 administration and Mitigation. Other Stuff.

SCR 136

“These (disputing) parties are negotiating a framework for settlement that makes it critical that the State of Idaho Water

Resource Board establish public policy with regard to the future management of

the aquifer system”

First Phase

Development of a “Framework Plan” which was presented to, approved and funded by the 2007 Legislature.

Second Phase

Development of a comprehensive management plan was authorized by HCR 28 and funded by HB320.

Scope Process to be open to public. Plan to be comprehensive but have sideboards. Plan Framework should include interim measures

that can be implemented before final plan. Plan should address; Aquifer management goals

and level of management to adjust demand and legally useable supply.

Preliminary Approach The Board has determined that the most effective way to engage the public, affected parties to ongoing litigation and stakeholder groups is to formulate a series of Aquifer Management Alternatives which will be based on adjusting or balancing water demand and legally and administratively available supply.

Specific Approach (cont’d) Include specific measures and techniques

that can be used to accomplish the desired water budget adjustments.

Costs for implementation of the various management levels will be determined.

Initial evaluation of the state and local economic cost/benefit of the alternatives will be undertaken.

Specific Approach Adaptive mechanisms to quantify progress

and adjust implementation measures to be incorporated.

Funding mechanisms, including development of a fee structure, to support selected management alternatives.

Managed Recharge Incidental Recharge Site-Specific Augmentation Additional Surface Water Storage and

Weather Modification Conversions – Groundwater to Surface Water Exchange for water acquired or leased from

below Milner.

Management Alternatives

Sustain the economic viability and social and environmental health of the Eastern Snake Plain by adaptively managing a balance between water use and supplies.

Goal for Aquifer Management

Increase predictability for water users by managing for reliable supply

Create alternatives to administrative curtailment

Manage overall demand for water within the Eastern Snake Plain

Increase recharge to the aquifer Reduce withdrawals from the aquifer

Objectives for Aquifer Management

Board solicited nominations and formed Advisory Committee

Committee makes consensus recommendations to the Board

CAMP Progress Committee has established Operating Protocols. Quantitative Goals sub-committee formed. Committee is scheduled to meet monthly for 14 months. Committee to have recommendations to Water Board by

Summer 2008. Board will draft plan and hold public meetings Summer

and Fall 2008. Final ESPA Comprehensive Aquifer Management Plan to

be submitted to Legislature January 2009.

ESPA 2007 Mitigation Began discussions in early 2007 with water users

concerning what options may be employed to mitigate potential water shortages to senior users.

As year progressed water supply tanked and Supreme Court ruled on conjunctive management rules.

Continued meeting with affected water users to try and negotiate a deal to allow the junior users to operate.

2007 Mitigation (cont’d) After Supreme Court ruling and failure to reach

consensus on solution Director moved ahead with Orders issued in 2005.

Warning letters were sent to affected Junior users. Mitigation was proposed by Dairy industry, Food

processors and Ground water users. Director found the mitigation plans acceptable based on estimated impact to senior water rights.

Other ESPA STUFF Hearings are being scheduled for on-going litigation. Retired Supreme Court Justice Schroeder has been hired

as Hearing Officer for these delivery call cases. Director has requested that parties who have documented

interest in the Milner Hydropower water right application provide information that may be helpful to him before he makes a final decision on licensing the water right.

Technical studies including RFP for Weather Modification.

W-Canal Recharge Project Managed Recharge major component in Eastern

Snake water budget redistribution. Done additional technical studies and found that

injection wells are necessary to achieve goals. Declined BOR 2025 Grant Application because

of operational constraints required by NOAA Fish.

Moving ahead with a pilot effort which will include establishing water treatment methods and injection rates.

Interim Legislative Committee Presentation given in July meeting that

summarized water management issues around state in particular areas where we have potential or are experiencing conjunctive management issues.

Requested a proposal that included prioritized schedule and funding requirements for aquifer study and planning to be considered by Governor and Legislature.

Aquifer Study Basins Proposed Lower Boise/Treasure

Valley Rathdrum Prairie Big Wood Moscow-Pullman Mountain Home

Bear River Teton Big Lost Portneuf Blackfoot

North Idaho Adjudication First phase of adjudication authorized by

legislature. IDWR has been moving ahead with preparation,

technical design and acquisition of computer hardware and software.

Late local resistance to moving ahead has resulted in a delay of the actual claims taking process. Director and staff continue to hold information meetings to explain the adjudication effort.
