The gauge is located about 6 miles above the put-in. There are a few large creeks, so during and after rain events, the actual flow can be significantly higher
The Blue Hole Rapid and pool is a highlight of this run. In the past it was also a popular local swimming hole and paddlers have used it as as an access point. Unfortunately use grew to a point that was no longer tolerable to local property owners. King County owns a parcel at the Blue Hole (the pool at the bottom of the rapid) but the access from 114th Street requires walking along the levee on river left which crosses a small sliver of private parking. Despite signage installed by local property owners, parking and access to the river at the end of 114th Street is legal. You just can't legally walk downstream on the levee. Boaters who wish to take-out here could run the rapid, walk up the midstream island, and ferry across the top of the rapid to the shoreline at the street end of 114th Street.
