Lakes

Lakes are a critical freshwater resource providing an array of recreational opportunities, valuable habitat for fish and wildlife, and tranquil beauty. Our geologic history has led this area to be rich in lakes with Snohomish County having over 400 lakes. While the majority are very small or located in the Cascade mountains, there are around 60 lakes located in the populated lowland areas.
