The Oldest Man-Made Lake in Washington: Lake Tapps

Lake Tapps is one of the most popular locations for water activities, including boating and kayaking. Originally created by Puget Sound Power & Light, it currently serves 350,000 residents and thousands of businesses as their primary source of drinking water. With 45 miles of coastline, multiple neighborhoods share access privately within the community. The only way to get general access to the lake is by using the northeast shore, which features a boat ramp to traverse the 135-acre lake.

The original purpose of the lake was to harness hydroelectric power. When it stopped power production in 2004, Cascade Water Alliance bought it to give the local communities drinking water access. Nowadays, this lake is known for its year-round fishing opportunities, enticing anglers with the hope of catching crappies, perch, and muskies. The northeast shore has a boat ramp for anyone who wants to journey to the center of this 135-acre lake with their gear. If you decide to take a trip to the North Lake Tapps County Park, your view of Mount Rainier is unlike any other.

Where Is Lake Tapps: A Map

Lake Tapps is part of Pierce County. With the unique path of inlets, islands, and peninsula, the lake is east of Tacoma and west of Enumclaw. It covers about 4.5 square miles, receiving water from the White River via glume. While the support for hydropower generation is no longer there, the diversion dam remains in place.

Pierce County: The Home Of Lake Tapps

In Pierce County, Lake Tapps is just one of over 180 lakes, ponds, and reservoirs. With 23 cities within the county’s limits, there are 925,708 residents living there now. The only county with a higher population than Pierce County is King County, which has 2.2 million residents.

One of the biggest tourist attractions in Lake Tapps is Mount Rainier, a volcano and the tallest mountain of the Cascades. While it hasn’t erupted since the middle of the 19^th century, geologists believe it will erupt again at some point. Lake Tapps is one of the most prominent reservoirs locally, but Pierce County also has several arts organizations to attract tourists.

Wildlife Near Lake Tapps

Tiger Muskellunge

Tiger muskellunges are carnivorous, living in the northern United States in freshwater sources. They prefer quiet rivers and still water, including the Great Lakes. Washington is one of many states that stock tiger muskies. However, the Washington Department of Fish & Wildlife requires any catch under 50 inches to be released back into the lake.

Water temperature and availability of food play a role in how quickly tiger muskies grow. When temperatures drop below 68 degrees Fahrenheit, the likelihood of cannibalism rises. Their cylindrical body can exceed 45 inches in length, depending on their environment. The oldest manmade lake in Washington is one of only 7 lakes that these fish live in.

Yellow Perch

Yellow perch prefer slow rivers and streams or still bodies of water, making Lake Tapps an ideal home. At 4-10 inches long, these small fish are easy to identify by their separate dorsal fins and compressed golden body. As a sport fish, they are an easy but unique challenge for any type of angler, and their mild flavor makes them an ideal fish to harvest commercially.

Black Crappie

Another freshwater fish in Lake Tapps is the black crappie, measuring about 4-8 inches long at its adult size (though the biggest ever caught was 19.3 inches). It prefers to live in lakes, reservoirs, and other areas with relatively calm waters. They are easy to catch with a minnow rig or small jig. Since they aren’t listed with the IUCN as an at-risk species, anglers can freely fish for them with fewer restrictions than other species in the lake.
