CHK’s Memorial Day Roundup post was very popular, so I have repurposed it into a standing list that appears in the main menu and can be updated over time: Outdoor Pools, Spray Parks and Waterworks.
The content is the same as the blog post with two additions: Joe Cole Recreation Center’s spray park is just north of Florida Ave in Trinidad. Benning Stoddert Community Center, just over the river on East Cap, has a spray park, even though it doesn’t show up on DPR’s map of spray parks. Thank you, readers Elizabeth and Leah, for letting me know about Benning Stoddert and Joe Cole!
