SB 37 — Strategic Water Reserve Fund (Final / Enacted version)

Status: Signed / Chaptered (2025)
Subject: Water management, water rights, finance (Strategic Water Reserve)
Primary agency: Interstate Stream Commission (ISC) / Office of the State Engineer (OSE)

Main purpose

Create a permanent, nonreverting funding mechanism to support New Mexico’s Strategic Water Reserve and expand/clarify ISC authority and procedures for acquiring, managing, and prioritizing water and water rights intended to protect streamflows, support aquifer recharge, and pursue related environmental and public-benefit objectives.

Key provisions

  • Strategic Water Reserve Fund
    • Establishes the “Strategic Water Reserve Fund” in the state treasury to receive appropriations, gifts, grants, donations and investment income.
    • Fund cap: $15,000,000. Any year‑end balance above $15M reverts to the general fund.
    • Money in the fund is appropriated to ISC for Strategic Water Reserve purposes (Section 72‑14‑3.3).
    • Over any five‑year period, no more than 25% of fund expenditures may be used for aquifer recharge / groundwater depletion reduction (Paragraph (3), Subsection B).
  • Administration and spending
    • ISC administers the fund; expenditures by warrant per standard state procedures.
    • ISC may accept federal or other grants, donations to purchase/lease water rights, pay administrative costs, and fund infrastructure for water delivery.
  • Acquisition rules and limits
    • ISC may purchase, lease, or receive by donation surface or underground water/water rights from willing sellers/lessors; acquisitions must be by ISC approval.
    • ISC shall pay no more than appraised market value; acquisitions by condemnation of water rights are prohibited (only real property needed for conveyance infrastructure may be condemned).
    • Water rights served by acequias/community ditches may not be acquired for the Reserve. Rights served by irrigation districts may be acquired only via contract with the district board or special water users association.
    • Water in the Reserve is not subject to forfeiture.
  • Authorized uses of Reserve water
    • Assist compliance with interstate stream compacts / decrees.
    • Support water management for threatened/endangered aquatic species (in coordination with collaborative programs).
    • Support aquifer recharge or reduce groundwater depletion to promote streamflow or other environmental benefits. Surface water acquired for recharge must be placed underground only via natural, passive infiltration through the streambed (active conversion methods restricted).
  • Prioritization, consultation, and supplementary benefits
    • ISC must develop river‑reach and groundwater basin priorities in consultation with NM interstate stream compact commissioners, OSE, State Department of Justice, and local governments and water entities (tribes, counties, municipalities, special districts, soil & water conservation districts, water authorities, water planning regions).
    • ISC may prioritize acquisitions that provide supplementary benefits (e.g., support traditional/cultural practices, habitat improvement, recreation) in addition to at least one core Reserve purpose.
  • Sales/leases and proceeds
    • ISC may sell or lease Reserve water/rights at no less than appraised market value; may sell only when rights are no longer needed for the Reserve purposes; water rights shall not be sold to the United States.
    • Proceeds from sales: portions appropriated to OSE for adjudication; remaining appropriated to ISC for Reserve purposes.

Who is affected

  • Interstate Stream Commission and Office of the State Engineer: new administrative responsibilities.
  • Water right holders and sellers (private, districts): creates a willing‑seller market option and sets limits (acequias excluded; irrigation districts only by contract).
  • Tribal nations, municipalities, counties, water planning entities and conservation districts: consulted in priority setting.
  • State budget: creates a new capped permanent fund and potential future appropriations.

Fiscal and implementation notes

  • Fund cap: $15 million; current related Reserve balances reported around $5.2M (per OSE/LFC materials).
  • Legislative Finance Committee (LFC) noted concerns with new dedicated fund design and potential erosion of legislative budget control.
  • OSE estimated possible recurring cost for an additional half‑time staff reviewer (~$75,000/year) to implement acquisition‑benefit review requirements.
  • LFC and OSE raised technical questions about ambiguous terms (e.g., “converted to groundwater”) and recommended clarifying amendments (some were adopted during committee process).

Timeline / procedural

  • ISC must administer the fund and follow the new acquisition, consultation, and prioritization procedures immediately upon the law’s effective date (as enacted). Effective date provisions varied in analysis documents; the bill as enacted is chaptered and effective per the session law.

Considerations / potential impacts

  • Provides a focused, dedicated funding source to support streamflow and limited aquifer recharge projects while placing a cap to limit fiscal exposure.
  • Protects acequia and (largely) irrigation district water from involuntary acquisition, addressing local water governance concerns.
  • The 25% five‑year cap on recharge expenditures reflects legislative intent to balance surface/groundwater strategies.
  • Implementation will require clear ISC/OSE rules and staff capacity to evaluate acquisitions, ensure compliance with limitations (no condemnation of water rights), and coordinate with local/tribal stakeholders.

For agencies or stakeholders preparing comments or proposals, key implementation issues to monitor include rulemaking clarifications (definitions and passive recharge standards), ISC staffing and procedural capacity, and any future appropriations into the new fund.
