Southwest Watershed Resource Center has prepared a self-guided walking tour of the SW Portland watershed. You can download a map, or pick one up at the Watershed Resource office office which is within the SWNI office in the
Multnomah Arts Center Room #5, 7688 SW Capitol Hwy.
The map has couple dozen points numbered. The walking route starts at the SW Community Center, goes through Gabriel Park, then Multnomah Village and over to the Raz-Baack Crossing before returning. The pamphlet which includes the map has a brief description of each of the numbered water quality projects.
