Mineral Wells Is Paying Off a Reservoir That May Never Get Built
Summary
Palo Pinto County's water district borrowed $94.7 million toward a $200 million reservoir, and the City of Mineral Wells raised its water rates to help repay the debt. When construction bids arrived in August 2025, they ran $150 million to $259.3 million above the money Texas had approved -- so the district paused construction indefinitely and paid a penalty to walk away from the rest of the loan.
An estimate built for a different market
The district's problem traces to how it priced the job. To apply for state financing, it relied on an estimate its engineer prepared in May 2022, adjusted only for two years of 5-percent inflation. The engineer's own cover letter warned the number was written during "a period of extreme financial pricing uncertainty" and recommended re-checking it every six months once a construction date was set; the district's contract with the engineer separately called for hiring an "independent cost estimator" for extra assurance. Neither happened.
On that estimate, the district applied for $200 million in financing assistance⧉ from the Texas Water Development Board (TWDB)⧉ -- the state agency that funds water infrastructure through low-interest loan programs -- in February 2024. TWDB approved it in July 2024, structured as three annual bond issuances of $60 million, $100 million, and $40 million. The district issued the first $60 million tranche in November 2024. When construction bids finally arrived in August 2025, they ranged from $350 million to $459.3 million -- 75% to nearly 130% above the money the state had approved, and three to four and a half times the $102.5 million the 2022 state water plan had on record for the same reservoir.

$94.7 million out, $62.3 million idle
Unable to close that gap, the district indefinitely postponed construction and cancelled the remaining $140 million of authorized borrowing -- paying TWDB a $70,753 penalty in February 2026 to walk away from it. That leaves $94.7 million in bonds already issued between 2009 and November 2024, on top of a $2.4 million state grant. Of that $94.7 million, the district has spent $32.4 million since 2009 on design, land acquisition, and related work. The remaining $62.3 million sits unspent, mostly in escrow accounts TWDB itself controls -- and as of March 2026, the audit found, the district had not announced any plan for what happens to it. The debt does not disappear because the reservoir stalled; only the plan for finishing the project did.

Mineral Wells pays the bond either way
The district's bonds are guaranteed by the City of Mineral Wells, which is contractually required to repay them through its water purchases from the district -- and the city raised its own water rates to generate that repayment revenue. It is not a small share of the district's books: of the roughly $26.2 million the district collected from its three water customers between September 2023 and December 2025, 96.4%, or about $25.2 million, came from Mineral Wells alone. Auditors tested the district's revenue and expenditure records, including 27 of the 134 Turkey Peak-related transactions, and found them accurately recorded and compliant with TWDB's program rules -- the money that has moved so far was handled properly. What the audit does not resolve is what the reservoir was for: without it, the regional water plan projects Palo Pinto's service area running an annual shortfall of 1.3 billion gallons by 2040, growing to 1.6 billion gallons by 2080. During the 2015 drought, a TWDB report found Lake Palo Pinto's storage had already fallen to 8% of capacity.
The takeaway
- A ratepayer-backed loan outran its own cost estimate. The district borrowed against a 2022 engineering figure adjusted only for two years of inflation; by the time bids came in three years later, they were 75% to 130% above the $200 million the state had approved to finance the job.
- The debt is real even though the reservoir isn't. $94.7 million in bonds is already on the books, guaranteed by Mineral Wells ratepayers, with $62.3 million of it sitting unspent and no announced plan as of March 2026 for what happens to it.
- Auditors found no misuse of funds in what they tested -- only a broken forecast. Every expenditure in the audit's sample was proper and compliant; the failure here is a construction-cost estimate that ignored its own engineer's warning to keep re-checking it, not money going missing.
The audit does not allege fraud or misused funds -- the district's revenue collection and the sample of expenditures auditors tested, including on the Turkey Peak project itself, were found accurate, properly approved, and compliant with TWDB's financial-assistance rules. Auditors tested a targeted, non-representative sample (3% of general expenditures, 20% of Turkey Peak expenditures) and say explicitly that the results should not be projected onto the full $94.7 million in bond proceeds. The finding is narrower and structural: a cost estimate never re-verified against a volatile construction market, which left the district holding debt for a project it could no longer afford to build at the price it had planned for. The district agreed with every audit recommendation, including the auditors' call to keep working with TWDB and other stakeholders on solutions for the water shortages the reservoir was meant to prevent -- but the audit sets no deadline for that, and the district's own $62.3 million in idle bond funds still has no stated destination.

Finds the district took on approximately $94.7 million in bond debt for a reservoir whose construction bids came in far above the money secured, paused construction indefinitely, and paid a cancellation penalty on the unused portion of its financing.

The Palo Pinto County Municipal Water District No. 1 is a small local government unit whose job is to deliver water to a handful of customers in North Texas, chief among them the City of Mineral Wells. For nearly two decades it has been trying to build the Turkey Peak Reservoir, a dam and reservoir downstream of the district's existing Lake Palo Pinto meant to head off water shortages the region's own water plan projects for the 2040s and beyond. A July 2026 audit⧉ from the Texas State Auditor's Office -- the state's independent, constitutionally established auditor -- found the district is now unable to finish it. It has taken on approximately $94.7 million in bond debt for the project, and construction is paused indefinitely.
