This might be a nice place to fish if you have a ton of money to pay the fees. A launch pass for the six months its usable is 200 bucks. WOW
Lake Tapps is currently open year-round, including the intake canal to within 400 feet of the screen at Dingle Basin. The lake offers very good opportunities for largemouth and smallmouth bass as well as tiger muskies. There is also good fishing for yellow perch and black crappie. Anglers are reminded that all tiger muskies less than 50 inches must be released.
Water access is provided at Lake Tapps North Park (Pierce County) on the northeast shore, which provides a boat ramp, bathrooms, and plenty of bank access. Also, the city of Bonney Lake provides a launch and docks along the western shore at Allan Yorke Park.
The lake's water level is normally down throughout the winter and early spring, which may limit boat access. There remains limited shoreline access at the public access sites.
THERE ARE LAUNCH AND PARKING FEES FOR BOTH THE NORTH AND SOUTH LAUNCHES ON THIS LAKE.

Lake Tapps is a reservoir in Pierce County, Washington. It was created in 1911 and is maintained by Puget Sound Energy. A diversion dam on the White River, near Buckley, Washington, routes water into a flume which empties into the east side of Lake Tapps. On the west side of the lake water is routed to the "Dieringer Powerhouse" to generate hydroelectricity, after which the water is returned to the White River, about 20 miles (32 km) downstream from the diversion dam. The level of the lake is lowered from October to April for flood control purposes, rendering it unusable for recreation half of the year.
