Lake Crabapple

Lake Crabapple is located just east of Lake Goodwin in the Seven Lakes area north of the Tulalip Reservation.  The lake is roughly 38 acres with an average depth of 5.5 meters.  The watershed of Lake Crabapple is about 754 acres and includes Lake Loma to the east.  There is a public boat launch on the north side of the lake.  Gas-powered boats are not permitted.

Water Quality Information

Summary

Lake Crabapple has moderate water clarity, low phosphorus, and low to moderate algae.  The lake shows some signs of increasing eutrophication.  Therefore, the lake may be at risk of future declines in water quality unless nutrient runoff from land development in the surrounding watershed is controlled.

 

Reports

A comprehensive Snohomish County State of the Lakes Report was produced in 2003 and includes a specific section on Lake Crabapple.  Individual lake updates to this report are provided each year as new data are collected.  

 

Data

Snohomish County Surface Water Management (SWM) together with volunteer lake-monitors have been collecting water quality data for Lake Crabapple since 1994.  Current and historical lake water quality data are available online in SWM's interactive Water Quality Database.
