Water Levels on Lake Dunlap

Current Conditions: Fully Restored to Normal Pool

Lake Dunlap has been fully restored to its historic normal pool elevation of 575.8 feet above mean sea level since October 26, 2023, when the rebuilt dam completed refilling. As of this writing, the lake operates normally, with hydroelectric generation resumed and no restrictions tied to the 2019-2023 crisis remaining in effect.

The Failure: A Sunny-Day Collapse With No Storm Involved

On May 14, 2019, at 8:05 AM, one of the dam's two spillgates catastrophically failed on a clear, calm morning, a genuine "sunny day failure" with no flood or storm event involved. The cause was aging, degraded structural steel in the roughly 90-year-old gate mechanism. The lake drained essentially completely within about 24 hours, leaving lakefront wells dry and lake-dependent businesses facing closure.

The Failure Exposed a Systemic Crisis Across the Entire Chain

Lake Dunlap's failure revealed that the entire chain of six 1927-1932-era hydroelectric dams was near or past its roughly 75-year design life, already 15 years overdue by 2019. In September 2019, GBRA announced plans to proactively drain four lakes citing safety concerns, triggering two lawsuits from more than 300 residents seeking to block drainage until a repair plan existed.

Litigation Ran for Nearly Four Years

A temporary injunction and settlement on September 16, 2019 kept most lakes closed to recreation except Dunlap while an independent expert panel assessed safety. One lawsuit, Williams v. GBRA, wasn't formally dismissed with prejudice until March 1, 2023, nearly four years after the original failure, overlapping directly with the physical reconstruction underway at the time.

GBRA's Inability to Tax Forced a Novel Funding Solution

Because GBRA has no legal taxing authority, and these are recreational rather than flood-control dams, standard state and federal disaster or flood-control repair funds weren't available. Estimates for repairing the full six-dam system ranged from $70 to $180 million. The solution: create local water control and improvement districts at each lake that could combine property taxes with hydroelectric revenue to bond out reconstruction.

Voters Approved the Lake Dunlap WCID in November 2020

Guadalupe and Comal county voters approved creation of the Lake Dunlap Water Control and Improvement District on November 3, 2020, alongside similar districts for Lake McQueeney and Lake Placid. The Texas Water Development Board approved $40 million in Clean Water State Revolving Fund financing for Lake Dunlap's new dam that December and January.

Construction Ran From May 2021 to August 2023

Zachry Construction Corporation began work on May 14, 2021, exactly two years after the failure, replacing the old bear-trap gates with modern hydraulically actuated steel crest gates along with structural, mechanical, electrical, and control-system upgrades. The first hydraulic crest gate installation began in February 2023, and reconstruction was substantially complete by August 31, 2023.

The Total Rebuild Cost $40 Million

The full reconstruction cost $40 million, funded through 30-year bonds repaid by a combination of Lake Dunlap WCID property taxes on waterfront residents and 100 percent of the rebuilt plant's gross hydroelectric revenue, roughly $800,000 annually, donated by GBRA to the WCID specifically to help service that debt.

Half the Chain Remains Drained Today

Lake Dunlap is one of only three lakes in this six-lake chain, alongside Lake McQueeney and Lake Placid, to reach full restoration. Lake Wood, Lake Gonzales, and Meadow Lake remain drained with no secured funding as of this writing, a genuinely important comparison point for any buyer evaluating this stretch of the Guadalupe River.

The Rebuilt Gates Pass Slightly Less Water Downstream

The new hydraulic crest gates installed during reconstruction pass somewhat less water than the original 90-year-old gates, leaving a roughly two-mile stretch of river below the dam with reduced flow, a minor but genuinely distinctive change worth understanding for any property along that specific downstream stretch.

Track Current Conditions Through GBRA Directly

Given the dam's documented failure history, confirm current lake conditions and any ongoing maintenance activity directly through GBRA before any property visit or boating trip, rather than assuming the lake's current full-pool status is guaranteed to remain unchanged indefinitely.

The Original Gates Held an Engineering Distinction Before Their Replacement

Before being replaced, Lake Dunlap's original Huber and Lutz roof-weir spillgates were documented as the largest and oldest known examples of that gate type in Texas, representing the first recorded use of roof-weir spillway gates anywhere in the state, a genuinely notable piece of engineering history now preserved only in documentation rather than in the physical structure itself.

Upstream Regulation From Canyon Reservoir Adds Another Layer of Context

Flow into Lake Dunlap has been partly regulated by releases from Canyon Reservoir since June 1964, meaning water levels here have always depended partly on decisions made well upstream, a factor worth understanding separately from the dam's own structural history and its 2019-2023 crisis.

Compare This Recovery Story to Lake Wood's Ongoing Limbo

Lake Wood, immediately upstream of Dunlap on the same chain, failed in March 2016, years before Dunlap, yet remains drained today with no WCID formed and no funding source identified, according to a 2021 Texas Water Development Board report. Dunlap's successful resolution stands in genuine contrast to its neighbor's continued uncertainty.

What This Means for Your Search

Lake Dunlap's water-level history includes a genuine sunny-day dam failure, four years of complete drainage, nearly four years of litigation, and a successful $40 million rebuild completed in October 2023. Confirm current conditions directly, and understand that this reservoir's risk profile is now fundamentally different, and considerably more reassuring, than it was during the 2019-2023 crisis years.
