Lake Chelan ready to welcome 2014 summer visitors

Lake Chelan draws thousands of visitors and residents to its shores each year. Whether the purpose is to fish, swim, boat or simply meander along its shores, the lake is a popular gathering place. It’s also a vital part of the Chelan County PUD network of hydroelectric resources.

A forecast of near normal runoff for 2014 makes it likely residents and Lake Chelan visitors will find conditions favorable for summer recreation this year. During refill this spring, the level of Lake Chelan is expected to be within or above the annual expected operating range for dry to average water years. Minimum (target) lake levels are expected to be met unless spring runoff is late. 

This video shows how we measure snowpack to forecast our water supply outlook:

 

Information about lake levels is available in real time on this page. For those on the go, posters at boat launches and marinas and rack cards distributed throughout the Chelan-Manson-Chelan Falls community display a QR (Quick Response) code that offers a direct link to current lake level readings by using their smart phones and tablets.

Lake Chelan is the reservoir for the Lake Chelan Hydro Project. Managing the level of popular Lake Chelan requires balancing seven objectives in the operating license that together provide recreation, protect fish, reduce erosion and restore year-round flows to the Chelan River.

Managing the level of the lake is not an exact science. It involves a series of forecasts and calculations, with the added uncertainty of weather. However, updated tools and additional data will help us provide information that is more useful for residents and visitors.

Future Operation

July 25: The level of Lake Chelan is expected to be operated with the top foot of the reservoir, from elevation 1,099 - 1,100 ft. for the remainder of July and through the month of August. Lake levels are anticipated to remain within the expected operating range for dry and average water years. Lake levels will fluctuate as affected by weather, inflow, generation and spill.

Targeting a Range

Chelan PUD estimates that Lake Chelan can be operated more consistently within the expected range shown on the Dry/Average Water Years graph 90 percent of the time and meet the District’s seven license operating objectives in most years.

We are committed to letting you know about any changes in expected lake levels as soon as we can so residents and visitors know what to expect. We welcome your comments or questions about Lake Chelan levels.

The District expects to maintain a range of 1,085 to 1,100 feet above sea level during dry or average water years. In wet water years lake level could fall to 1,083 feet or lower (the license minimum is 1,079 feet) as more room is needed for increased runoff. Factors that can affect lake level management include:

  • High runoff due to a wet water year
  • Early or late snow melt
  • Project operation and/or maintenance needs
  • Energy market conditions
 
Public Boat Ramps at Lake Chelan

We are sensitive to the needs of the many users of Lake Chelan. Below are the elevations at the bottom of each concrete boat ramp. As lake levels fluctuate, boaters are asked to take these elevations into consideration before launching a boat.
