Idaho Water Resources leaders outline recharge priorities, $30 million ongoing request and five new water-administration positions

At a budget hearing before the Idaho Joint Finance-Appropriations Committee, Idaho Department of Water Resources Director Matt Weaver and Idaho Water Resource Board Chairman Jeff Raybould described the agency’s spending, major projects and staffing requests, and urged continued funding for statewide water projects.

The presentation, delivered by Janet Jessup, budget and policy analyst for Legislative Services, laid out the department’s fund structure, recent ARPA-related inflows and a governor’s recommendation to add $30 million in ongoing general-fund support to the water management fund. Director Weaver and Chairman Raybould answered questions for the committee about how existing balances are committed and how additional funds would be used.

Jessup told the committee the Department of Water Resources oversees water-right administration under Title 42 of Idaho Code and that the Idaho Water Resource Board has project and bonding authority pursuant to Article 14 of the Idaho Constitution. She highlighted that fiscal-year activity included a large ARPA infusion split between a one-time $50 million appropriation and a separate $50 million made ongoing in 2023, and directed members to fund-level PDFs in the committee SharePoint for detailed commitments and expenditures.

Weaver argued the department needs staff to support expanding water-district administration and growing workload. He requested five additional full-time positions to create a Water Administration Bureau — including a bureau chief and technical records specialist — to pair with about 11 existing staff now performing similar functions. Weaver said the request was driven in part by obligations tied to a settlement on the Eastern Snake Plain (ESPA) and the expectation that more basins will require district creation and administration.

“We are not meeting the demand to create and support water districts across the state,” Director Matt Weaver said, noting specific interest in forming districts in basins south of the Snake River, in the Lower Clearwater and in parts of the Upper Salmon.

Chairman Jeff Raybould described where water-management account money has been committed: Mountain Home Air Force Base pipeline and pumping infrastructure, work related to the Anderson Ranch dam raise, a pipeline from Dworshak (Dworshak Dam area) to fish hatcheries, storage and carryover adjustments for Bear Lake, the Priest Lake water-management project, loans and grants for canal conversions and groundwater-to-surface-water conversion projects, a Treasure Valley supply assessment and various canal efficiency improvements. Raybould said some funds are issued as progress-based loans and some as grants, depending on project criteria and state benefit analyses.

On the water-management account balance, Weaver summarized materials in the committee packet: an end-of-2024 cash balance of about $293 million, revenues of roughly $38 million through December 31, expenditures near $11.2 million, and a total of approximately $290 million in committed funds — leaving about $29 million uncommitted. Raybould confirmed that large portions of the balance are tied up in loans, grants and multi-year projects rather than idle cash.

The committee pressed the board on timing and pace. Raybould and Weaver said large projects require engineering and staged payments; funding is released as work progresses, so some appropriations remain on the books while projects complete multi-year designs and construction. Raybould urged applicants to bring projects forward promptly so the board can evaluate and accelerate work where feasible.

Replenishing the Eastern Snake Plain aquifer was a recurring topic. Weaver and Raybould explained state-sponsored recharge averages and targets: state-sponsored recharge averaged about 268,000 acre-feet per year from 2016–2024, private recharge averaged about 116,000 acre-feet per year, and aggregated aquifer management activities (including pumping reductions) averaged roughly 600,000 acre-feet per year over that period. Raybould said the management target for the ESPA has been moved toward 350,000 acre-feet (from 250,000), because more recharge reduces the amount of mandatory pumping reductions required from groundwater users.

Committee members raised process and oversight questions about whether the requested $30 million ongoing should be appropriated as a recurring base or managed via project-specific approvals. Raybould and Weaver said the ongoing funding would support long-term priorities such as recharge capacity, operations and maintenance, monitoring, and other programmatic needs that benefit from a predictable revenue stream. Both noted that many projects previously funded with ARPA will continue to require ongoing operations, monitoring and, in some cases, loan servicing.

Weaver also explained an operational expectation from the ESPA settlement: by April 1, a year from that deadline, roughly 5,000–6,000 wellheads in the ESPA must report measured pumping in real time, a data requirement that will require substantial boots-on-the-ground effort. Weaver said a full compliance effort could require 12–15 positions, but the department proposed a leaner five-position package balanced with contributions from groundwater and water districts.

The committee heard specifics about how the board decides between grants and loans. Raybould said the board considers project importance to the state, the applicant’s ability to fund the work, and cost–benefit allocations (for example, a negotiated 89% state share for the Anderson Ranch dam raise under federal law where federal benefits and state benefits were apportioned). The board uses grants to bridge financing gaps (for example, paying up to one‑third of certain aging-infrastructure projects up to specified caps) and loans where repayment and collateral (often water rights) make sense.

The department and board provided numerous examples of funded and in-progress projects, including Mountain Home AFB water supply, Anderson Ranch raise, Lewiston Orchards conversion work, the Raft River pipeline, Treasure Valley water-supply assessment, Upper Payette Basin storage work, and canal efficiency and conversion projects intended to enable recharge.

The hearing closed with committee members asking for further detail on the board’s unfunded project list and project-by-project schedules; Jessup said she would follow up with committee materials. Weaver and Raybould urged the committee to weigh the benefits of predictable ongoing funding against doing piece‑by‑piece appropriations for individual projects.

Looking ahead, the committee will consider the department’s fiscal year 2026 requests and the legislature’s options for authorizing one-time project funding versus ongoing base funding for recharge capacity, administration and long-term monitoring.
