 When the park's initial construction was completed in 1999, the day-use park opened.A that time the park had the boat launch, tennis courts, trails (two miles worth, one mile (1.6 km) paved), two pedestrian bridges, a pond, picnic areas, parking, and the River House designed for accommodating meetings.Funds for the work came from Metro, private donations, the Tualatin Valley Water Quality Fund, and city funds.
