Waterworks Park Issaquah 1984 Pin

Anyone who has lived in western Washington knows that water parks aren't exactly compatible with the weather, and having one open for the few months that you *may* have warm enough temps to enjoy them isn't really economically viable. While that may be the case, that didn't stop developers from building one in Issaquah, Washington back in 1984. Located at the south end of Lake Sammamish and just off I-90 in an area that is now just one ginormous business park, Waterworks Park claimed to offer more than a mile of waterslides. Built on a massive pile of excavated earth from the Mount Baker Tunnel project in Seattle, the park was sitting on an artificial mountain on land that would all too soon be too valuable, leading to its closure in 1988.
