Lake Sammamish is a prized fishing destination located in King County, Washington, approximately 15 miles east of Seattle. As the second largest lake in King County covering nearly 5,000 acres (approximately 8 square miles), it forms a natural boundary between Seattle's eastern suburbs and less developed areas. The lake averages 30 feet in elevation and offers anglers diverse opportunities to target various species throughout the year. Lake Sammamish is part of the Lake Washington watershed, with Issaquah Creek as its main tributary entering at the southern end, and the Sammamish River as its outlet connecting to Lake Washington. While the lake's size is impressive, public access is somewhat limited, making it something of a hidden gem for local anglers who know where and how to fish its productive waters.
