Water Levels at Lake Chelan

Chelan County PUD Owns and Operates Lake Chelan Dam at the Outlet

Chelan County PUD owns and operates Lake Chelan Dam at the outlet near the town of Chelan, originally built between 1926 and 1928 and purchased by the PUD in 1955, raising the lake's level roughly 21 feet above its natural elevation.

The FERC License Permits an Operating Range Between 1,079 and 1,100 Feet

The federal license permits an operating range between 1,079 and 1,100 feet, with the PUD targeting 1,084 to 1,100 feet in most years and occasionally allowing the level down to 1,083 feet during unusually wet years.

The Seasonal Pattern Runs Spring Refill, Summer Peak, Fall Drawdown, Winter Low

The seasonal pattern runs a spring refill from April through June, a summer peak through July and August, a fall drawdown in September and October for winter flood storage, and a winter low from November through March.

The 1,096-Foot Threshold Determines Upper-Lake Dock and Boat-Lift Access Each Spring

The 1,096-foot threshold determines when upper-lake dock and boat-lift access becomes possible each spring, typically crossed sometime between mid-May and early June, and buyers with upper-lake property should confirm this seasonal timing rather than assume full access from the very start of spring.

A Historic 1894 Flood Destroyed Predecessor Dams Before the Current Dam Existed

A historic June 1894 flood raised the lake 11 feet above the prior high-water mark, destroying predecessor dams and flooding the town, though no comparably severe flood has been documented since the current dam's construction in 1927-28.

The Dam Operates as a Store-and-Release Peaking Hydroelectric Plant

The dam operates as a store-and-release peaking hydroelectric plant with roughly 59.2 megawatts installed capacity, generating power on a schedule tied to electricity demand rather than simply passing through a constant flow.

The Current Federal License Runs Through 2056 Following a 2003 Settlement

The current federal license runs through 2056 following a settlement finalized in October 2003 among state and federal agencies, tribal representatives, and conservation groups, which restored year-round minimum flows to the Chelan River below the dam after decades of the river being largely dewatered.

Washington Department of Ecology Regulates Water Quality Below the Dam Separately

Washington Department of Ecology regulates water quality in the Chelan River below the dam separately from lake-level management itself, with a 2021 rulemaking specifically addressing temperature and dissolved-oxygen standards after a decade of river restoration work.

A State Water Right Reserve Sets Aside Water for Domestic and Irrigation Use

A state water right reserve sets aside up to 65,000 acre-feet per year for domestic and irrigation use under a 1992 agreement tied to an original 1925 water right, with a portion still unallocated as of the most recent published figures.

Confirm Current Water Level Data Directly Through Chelan County PUD's Public Reporting

Buyers should confirm current water level data directly through Chelan County PUD's public reporting tools before assuming a specific historical figure still applies, since water years vary considerably based on winter snowpack and spring runoff timing.

Compare This Water Level System Honestly Against Other Western Lake Markets Covered on This Site

Buyers weighing Lake Chelan against other Western lake markets covered on this site should compare the specific combination of a long-term federal license, a predictable seasonal drawdown schedule, and the operationally important 1,096-foot spring threshold, truly and reliably so, for every buyer serious about this particular lake.

Waterfront Owners Adjust Boat Lifts and Docks Around the Predictable Seasonal Swing

Waterfront owners adjust boat lifts and floating docks around the predictable seasonal swing between full summer pool and the lower drawdown period, and buyers should ask a seller how their specific dock and lift system handles this seasonal elevation change firsthand.

Upper-Lake Shallower Coves Reflect the Drawdown More Visibly Than the Deep Central Basin

Upper-lake shallower coves reflect the seasonal drawdown more visibly than the lake's much deeper central Lucerne basin, and buyers touring shallower-cove properties in early spring or late fall should expect a more dramatic visual difference from peak-summer listing photos than a deep-water property would show.

Stehekin-Area Access Depends on Lake Level for Certain Dock and Ferry Landing Conditions

Stehekin-area access depends on lake level for certain dock and ferry landing conditions at the extreme upper end of the lake, and buyers or frequent visitors relying on the Lady of the Lake ferry schedule should stay aware of how seasonal water levels can affect specific landing operations, truly and reliably so, season after genuine season, year after genuine year, for every visitor relying on this particular transportation lifeline.

Confirm Current Level Charts Directly Rather Than Relying on a Prior Season's Snapshot

Buyers should confirm current level charts directly rather than relying on a prior season's snapshot, since Chelan County PUD publishes updated data reflecting actual conditions that shift year to year with snowpack and runoff timing across the broader watershed.

Winterization and Dock Removal Follow the Fall Drawdown Schedule Each Year

Winterization and dock removal follow the fall drawdown schedule each year, and waterfront owners should plan ahead for this predictable annual transition rather than being caught off guard by falling water each September and October.
