Overview Fishhook Park is located on the shores on Lake Sacajawea in Eastern Washington. The lake is formed by Ice Harbor Lock and Dam on the Lower Snake River. The park was named for Fishhook Rapids, which were once nearby, where Lewis and Clark spent time in October 1805.

Because sites are booked months ahead, a steady share of reservations get cancelled as trips fall through. Each cancellation instantly returns that site and those nights to the official calendar — first-come, first-served, no waitlist, no announcement. Refreshing the booking page yourself, every few minutes for weeks, works in theory. In practice, the people who get these sites are the ones who hear about the opening first.
ItOpened scans the Recreation.gov calendar for Fishhook Park around the clock. When a site matching your dates and your vehicle opens, you get a text with a direct link to it.
