Lake Tapps was originally a series of smaller lakes and marshes before being transformed into a reservoir in the early 20th century for hydroelectric power.
The water level is typically lowered in late autumn and raised in late spring to accommodate maintenance and water management cycles.
The reservoir is fed primarily by the White River.
The park serves as a hub for local recreational boating, including wakeboarding and jet skiing, due to the reservoir's size.
The park provides clear views of Mount Rainier on days with low cloud cover.
Lake Tapps Park, located on the northern shore of a massive 2,675-acre reservoir, serves as a primary public access point for water-based recreation in Bonney Lake, Washington. The site provides a multi-lane concrete boat ramp facilitating access to the reservoir, which functions as a water storage facility for Cascade Water Alliance. Visitors have access to designated sandy swimming areas and extensive lawn space for picnicking. The park's shoreline is characterized by calm, shallow entries suitable for families. The facility is managed by Pierce County Parks and maintains several open-air shelters. The reservoir itself features over 45 miles of shoreline, much of which is privately owned residential property, making public access points like this park vital. Parking facilities are sized to accommodate vehicles with boat trailers during peak season. Water levels in the reservoir are subject to seasonal fluctuations regulated for utility and environmental management.

Arrive early on weekends during summer, as the boat launch parking lot reaches capacity quickly.
Wear water shoes, as the lake bottom can be rocky in some areas near the swimming beach.
Check the Pierce County website for water level updates before planning a boating trip in the off-season.
Do not attempt to swim in non-designated areas near the boat ramp where boat traffic is active and dangerous.
Park facilities, including restrooms and the boat launch, may have reduced availability or seasonal closures during the winter months.
No alcohol is permitted in the park; pets must be leashed at all times.
