Heavy rain causes sewer overflow to the Willamette River
Today’s rainstorm caused Portland’s combined sewer system to overflow to the Willamette River. The public should avoid contact with Willamette River water from just south of the Sellwood Bridge downstream to the Willamette’s confluence with the Columbia River near Kelley Point Park for 48 hours after the combined sewer overflow (CSO) event ends.

The Alder Creek restoration project is a 52-acre refuge for native fish and wildlife near the Willamette’s Sauvie Island, in Portland, Oregon. Wapato Island, as it is known locally, has been a traditional fishing, hunting and gathering area for tribes for more than 10,000 years.
David Farrer, Toxicologist, Oregon Health Authority and Aaron Borisenko, Water Quality Monitoring Manager, Oregon Department of Environmental Quality, Laboratory Environmental Assessment Division described what Blue-Green Algae is, when it can become a concern, how it naturally occurs and what is known about conditions that create a bloom of algae.
Attached below are their slide show presentations. Additional information is available at the Oregon Health Authority's blue-green algae website.

City maintenance crews responded to a reported sewage leak on Sunday, September 28 near 6221 N Basin Avenue on Swan Island and found sewage overflowing through a vault cover in the street. Sewage from the vault was flowing across the pavement, and an unknown amount of sewage flowed into the Swan Island Basin of the Willamette River just north of the Swan Island Boat Ramp.
On the southern tip of Sauvie Island, an old farm and sawmill property is being handed back to nature.
This spring, demolition crews tore down the 1960s-era Alder Creek Mill, and excavators are removing fill dirt piled onto the site for 85 years, to recast the land for salmon, lamprey, mink, eagles and osprey.

Groundwork Portland and Columbia Riverkeeper are excited to announce Two Rivers, One City. The event will bring a broad network of river users together to share their stake in clean water. It will highlight the value that the Willamette and the Columbia hold for different communities in the Portland area, and discuss current threats to the health and prosperity of these waterways.
This summer habitat restoration efforts are underway on the southern tip of Sauvie Island in Portland, Oregon. Alder Creek is the first habitat restoration project that will be implemented specifically to benefit fish and wildlife affected by contamination in the Portland Harbor Superfund site. The project will provide habitat for salmon, lamprey, mink, bald eagle, osprey, and other native fish and wildlife living in the area.

Portland's cleanup needs to achieve the right environmental and economic goals without ending up in a thicket of lawsuits. Each goal needs to be rational and doable; each can be the other's complement. Oregon has forged rational and doable approaches when it comes to salmon protection and the allocation of scarce water in the Klamath Basin. It can help find one for Portland Harbor, too.
