Catkin Marsh

Here are a couple of photos from Portland's Catkin Marsh Natural Area, an obscure city park in industrial NE Portland on a branch of the Columbia Slough, east of NE 33rd and west of the airport. The park consists of a 53 acre wetland area -- surrounded on three sides by the now-defunct Broadmoor golf course, and the fourth by warehouses -- plus a long skinny strip of land along the south side of the slough connecting out to 33rd, which is the only part shown in the photos. I took these while stopped briefly along 33rd after taking the car through DEQ at the test station nearby. I didn't actually turn the car off, much less get out for a closer look, so the photoset is somewhat less than comprehensive this time around.

The city bought the land fairly recently, in December 2012 -- it was part of the golf course before that, maybe serving as a natural water hazard. It was included in the city's Natural Areas Restoration Plan when it was updated in 2015, which rated it in 'Fair' health and as a high priority for restoration, though without any specifics on what they might do about it. They did remove a couple of culverts blocking this section of slough in 2017, at least. And with that, we've covered just about everything the city's said publicly about the place.

I gather the longer-term plan is for an extension of the Columbia Slough Trail to run through here someday, which I imagine is gated on both money and acquiring land or easements further east so the trail doesn't just dead-end on an abandoned golf course or at the airport security fence. The new owners of the Broadmoor site want to build warehouse space there, so making a deal for the unbuildable wetland parts of the course seems doable, in theory.

For anyone feeling really impatient to go visit the rest of the park for some reason, on the map above you can see an unofficial boot path through this strip along the slough, and conceivably you could get there that way, on an unofficial basis. But note the chest-high tall grass in the photos, and remember it's growing on top of a muddy, slippery bank that you won't be able to see because grass. So you stand a really good chance of going for a swim, which I cannot recommend here. As a data point, the city advises not eating fish from the slough more than once a month, due to PCBs and other contaminants, and discarding most of the fish even then. The slough as a whole is not considered a Superfund site, on unspecified technical grounds, but I still think this would be a bad place to take a mud bath or see what the water tastes like. Ewww. Just ewwww.
