Bureau of Reclamation's Inflation Reduction Act drought-mitigation funds for the Lower Colorado River Basin, audited by the U.S. Department of the Interior Office of Inspector General

How Reclamation Kept $2 Billion in Drought Aid Off the Ledger

Summary

A Department of the Interior Inspector General audit found the Bureau of Reclamation awarded $2,012,453,952 of a $2.6 billion Colorado River drought-mitigation allocation as "miscellaneous obligations" -- an accounting category exempt from USASpending.gov -- and never documented a single check of whether the water districts and irrigation companies receiving that money were barred from federal business.

For two years, the Bureau of Reclamation has paid out Inflation Reduction Act drought money in the Lower Colorado River Basin through a bookkeeping category that keeps it off the federal government's own public spending ledger. A U.S. Department of the Interior Inspector General audit found that as of March 31, 2025, Reclamation had awarded $2,012,453,952 of a $2.6 billion allocation this way -- and never documented a single check of whether the water districts and irrigation companies receiving that money were barred from doing business with the federal government at all.

A pool built to fight drought, a category that hid the ledger

Section 50233 of the Inflation Reduction Act appropriated $4 billion through fiscal year 2026 for the Interior Department to mitigate drought, prioritizing the Colorado River Basin. Reclamation allocated $2.6 billion of that to the Lower Colorado River Basin -- $1.4 billion to short-term water-conservation payments ("Bucket 1," paying water-entitlement holders to fallow fields or cut use) and $1.2 billion to long-term infrastructure work ("Bucket 2"). Reclamation received 84 Bucket 2 project proposals alone, ranging from $327,000 to more than $1.4 billion each.

Reclamation chose to issue this money through water-related contracts recorded internally as "miscellaneous obligations" -- a category built for things like travel, training, and charge-card purchases, not $2 billion in drought aid. Unlike grants or cooperative agreements, miscellaneous obligations are not reported to USASpending.gov, the searchable public database the Federal Funding Accountability and Transparency Act was built to populate. Reclamation built its own IRA spending dashboard, but as of March 31, 2025 that dashboard was not publicly accessible either.

Zero checks on who was getting paid

Every recipient of federal money is supposed to be checked against the government's exclusions list -- the registry of entities barred from federal business over prior misconduct or noncompliance. Auditors reviewed Reclamation's Bucket 1 agreement files and found no documentation that any water-entitlement holder was ever checked before funds went out. Reclamation's own explanation was that its Boulder Canyon Operations Office simply had no formal process for running the check -- not that it ran the check and found nothing.

Reclamation's fix, once flagged it, only reached part of the problem. The Lower Colorado Basin region told auditors it had already started running exclusions checks through SAM.gov -- but the audit's recommendations were written to cover every Reclamation region, and auditors found that two other Reclamation regions had separately awarded about $271 million in IRA-funded miscellaneous obligations for drought mitigation that the Lower Basin fix does not touch. rated all three recommendations unresolved for that reason.

A companion April 2026 audit of Reclamation's Upper Colorado River Basin program found the identical gap in a different administrative structure there; Reclamation's own response to that audit went further, arguing water-entitlement holders were not even subject to exclusions checks in the first place -- a position this report's own findings contradict.

  • Reclamation awarded $2,012,453,952 of a $2.6 billion Lower Colorado Basin drought-mitigation allocation as "miscellaneous obligations" as of March 31, 2025 -- a bookkeeping category exempt from USASpending.gov, and Reclamation's own IRA spending dashboard was not publicly accessible either.
  • Auditors found no documentation that Reclamation checked a single Bucket 1 water-entitlement holder against the federal exclusions list before awarding funds, because the office administering the program had no formal process for doing so.
  • Reclamation's Lower Colorado Basin region began running exclusions checks after flagged the gap, but the fix does not extend to two other Reclamation regions that separately awarded roughly $271 million in the same unreported obligation category -- leaving all three recommendations rated unresolved.
  • Bucket 1 (short-term conservation payments) is 97.2% committed against its $1.4 billion allocation; Bucket 2 (long-term infrastructure) trails at 54.5% of its $1.2 billion allocation, with $548.9 million still unawarded as of the audit's cutoff.

All figures trace to DOI Office of Inspector General Report No. 2023-WR-035, "The Bureau of Reclamation Should Improve Transparency in Inflation Reduction Act-Funded Drought Mitigation Agreements and Check to Ensure Funds Are Not Awarded to Excluded Parties" (April 10, 2026), and to Section 50233 of the Inflation Reduction Act. This piece independently recomputed the bucket-level award rates -- 97.2% for Bucket 1, 54.5% for Bucket 2, 77.4% overall -- directly from the report's own Figure 5 dollar totals, and combined the report's Lower Basin awarded total with its separately stated $271 million other-region figure to show the known scale of the same gap (a combination the report itself does not total, and which spans two different measurement points, not a single as-of date).
