Canyon Lake Water Level: Current, History & 2026 Forecast

If you’ve been watching Canyon Lake drop over the past year, you’re not alone — the Texas reservoir sat at just 58.6% full as of April 22, 2026, about 22.5 feet below its conservation pool of 909 feet. That’s a long way from the 68% it briefly touched after the summer floods of 2025, when two boat ramps reopened and the mood lifted. This article tracks what the numbers actually show, which ramps are accessible right now, and what’s coming down the pipe — including a planned drawdown that will temporarily shut the lake starting September 2026.

Current Fullness: 58.6% as of 2026-04-22 · Pool Elevation: 886.48 feet · 24-Hour Change: +0.07 feet · Historical Peak: 950.02 ft on 07-06-2002 · 2026 Closure Start: Sept. 16, 2026

How low is Canyon Lake right now?

Canyon Lake was sitting at 58.6% of its total capacity as of April 22, 2026, according to readings from Water Data For Texas. The corresponding pool elevation that day was approximately 886.48 feet — roughly 22.5 feet below the conservation pool target of 909 feet above NGVD29. For comparison, statewide Texas reservoirs tracked by the same authority were holding at 74.5% full on the same date, placing Canyon Lake well below the Texas average.

Current elevation and percentage full

The most recent instantaneous reading on April 22 showed 886.49 feet, according to CanyonLake.co, with a 24-hour rise of just 0.07 feet. The lake remains significantly depleted, though the gradual upward creep suggests steady, if slow, recovery. The conservation pool at 909 feet is the level at which the reservoir can fully support its designed water supply and recreational functions.

Recent 24-hour changes

The lake gained 0.07 feet over the 24 hours preceding the April 22 reading, according to data from Water Data For Texas. That marginal daily increase illustrates the slow pace of rebound during drier periods, though the direction has been consistently upward over the past several weeks based on the difference between the April 19 reading of 886.36 feet and the April 22 level of 886.49 feet.

Will Canyon Lake ever fill back up?

The short answer is that it has done so before. Canyon Lake reached its recorded peak elevation of 950.02 feet on July 6, 2002 — nearly 41 feet above the current level — when heavy rainfall filled the reservoir well beyond its normal operating range. The 68% fullness mark reached after the unusually wet summer of 2025 shows the lake can recover substantially given sufficient rainfall in the watershed, though the path back to 909 feet remains uncertain.

Historical highs and lows

Beyond the 2002 peak, Canyon Lake has experienced significant swings throughout its operational history since impoundment in 1964. The post-July 4, 2025 rise from 46% to 68% fullness within a single wet season demonstrates how quickly conditions can shift, according to reporting from FOX San Antonio. The previous low of 46% had triggered boat ramp closures, illustrating how closely recreational access is tied to lake level fluctuations.

Factors influencing recovery

Several variables determine whether Canyon Lake returns to its conservation pool. Rainfall in the Guadalupe River watershed is the primary driver, supplemented by upstream runoff and managed releases from upstream reservoirs. Regional data from the U.S. Bureau of Reclamation shows Lake Powell inflow forecasts for Water Year 2026 at just 40% of normal, suggesting ongoing dryness in the broader Colorado River basin — though that figure applies to a different watershed, it signals that drought conditions remain a persistent risk across the Southwest.

Canyon Lake is currently experiencing historic low water levels, but there’s still plenty of water to enjoy.

How much did Canyon Lake rise after the flood?

The summer of 2025 brought an unusually wet period that drove a sharp reversal at Canyon Lake. According to FOX San Antonio, the lake climbed from 46% full before July 4 to 68% full after that date — a 22-percentage-point jump that triggered the reopening of Boat Ramps #1 and #2. The turnaround was dramatic enough to shift the mood for local businesses that had been bracing for drought impacts.

Texas floods impact

Flooding on the Guadalupe River following heavy rains upstream sent water pouring into Canyon Lake during the summer of 2025. The rapid rise from 46% to 68% fullness occurred within weeks, according to local reporting, demonstrating the reservoir’s sensitivity to watershed conditions. Some boat ramps were subsequently closed for assessment by the U.S. Army Corps of Engineers, the Water Oriented Recreation District (WORD), and Comal County following the high-water period.

Recent level increases

The April 2026 readings show the lake has since pulled back from those post-flood highs but has stabilized in the upper-50s percentage range. The 24-hour reading of +0.07 feet as of April 22 suggests the lake is still in a gradual climbing phase, though the pace is far slower than the rapid 2025 rise.

Is Canyon Lake closing in 2026?

Yes — but not permanently. Canyon Lake is scheduled to close for approximately four months starting September 16, 2026, to accommodate a drawdown project. The closure will allow work crews to carry out infrastructure improvements, including boat ramp extensions that should improve low-water access once the lake reopens.

Drawdown project details

Comal County is actively extending three boat ramps to improve their usability at lower water levels. According to LakeHouses4Sale.net, Boat Ramp #2 is receiving an extension of up to 25 feet along with six additional non-trailer parking spaces, which will lower its closure elevation to 892.88 feet from a higher threshold. Boat Ramp #7 is being extended by 100 feet, with its closure elevation adjusted to 900.00 feet, while Boat Ramp #8 is gaining up to 75 feet of length, bringing its closure elevation to 893.26 feet.

Closure timeline

The four-month closure window beginning September 16, 2026, is intended to complete the drawdown work with minimal disruption to peak recreational season. Once finished and the lake refills, the extended ramps should remain usable at lower water levels than before — an adaptation that local authorities are betting will reduce future closures as climate variability keeps lake levels in flux.

Canyon Lake water level forecast and history?

No site publishes a specific water-level forecast for Canyon Lake that extends months ahead. What exists instead are real-time gauges from U.S. Army Corps of Engineers water data portal and NOAA, along with historical records showing the lake’s range from a 2002 peak of 950.02 feet down to its post-drought lows. The best any visitor can do is monitor current readings and understand the closure elevations for the ramp they plan to use.

Forecast and charts

NOAA provides river forecasts for the Guadalupe River at Canyon Lake, which offer a proxy for near-term inflow expectations based on upstream precipitation models. The U.S. Bureau of Reclamation publishes regional inflow forecasts for Water Year 2026 — Lake Powell is projected at 40% of normal inflow — signaling that drought conditions across the broader region may keep pressure on reservoir levels. These forecasts don’t directly apply to Canyon Lake’s Guadalupe River watershed, but they offer a regional context for water managers and concerned readers.

Boat ramps status

Boat Ramp #14 at Canyon Lake is open daily from 8 AM to 6 PM under a first-come, first-served arrangement, charging $20 per vehicle for non-military visitors as of an April 2026 update. Boat Ramp #19 at Canyon Lake Marina operates from 9 AM to 5 PM except Tuesdays, also first-come, first-served. Boat Ramp #12 is accessible only to Lake Canyon Yacht Club members as of December 2025. The lowest closure elevation among documented ramps is 878.00 feet at Ramp #14, meaning that ramp stays usable longer during drawdowns than ramps with higher closure thresholds — Ramp #5, for example, closes at 905.15 feet.

What affects Canyon Lake water levels?

Water levels at Canyon Lake respond to a combination of rainfall in the Guadalupe River watershed, upstream reservoir management decisions, evaporation rates, and downstream water releases for municipal and agricultural use. The summer 2025 flood demonstrated how quickly the lake can rise when prolonged rainfall saturates the watershed, while the current 58.6% reading reflects months of below-average inflows since that high-water period.

Drought and recovery cycles

Central Texas is prone to multi-year drought cycles that strain reservoir levels, and Canyon Lake has weathered several such periods since its 1964 impoundment. The contrast between the 2002 peak of 950.02 feet and recent lows underscores the scale of variability. Local businesses, including marina operators, have reported that fluctuating water levels threaten tourism revenue, according to News4SanAntonio.

Canyon Lake has seen a significant rise in water levels, now at 68 percent full, up from 46 percent before July 4.

— FOX San Antonio

The county’s investment in ramp extensions reflects a pragmatic recognition that lower pool elevations are likely to recur. By lowering closure thresholds at key access points, Comal County officials aim to reduce the frequency of ramp shutdowns during dry periods — a direct response to the economic pressure that boat ramp closures place on local tourism and recreation businesses.

Summary

Canyon Lake sits at 58.6% full in late April 2026, well below its conservation pool and well below the Texas statewide average of 74.5%. The lake has bounced between dramatic highs and lows since impoundment in 1964 — briefly touching 68% after summer 2025 floods before pulling back — and faces a scheduled four-month closure beginning September 16, 2026. The drawdown will fund boat ramp extensions designed to improve low-water access going forward. For recreational visitors, select ramps remain operational, with Boat Ramp #18 being the most recent addition. For downstream water users, the persistent gap between current and target levels means conservation pool releases remain constrained. Monitoring current gauges from USACE or NOAA remains the most reliable way to track day-to-day changes, though long-range forecasts specific to Canyon Lake are not publicly available.
