Yeah, Seattle wants people to not wash their cars and instead a directs them to automated car washes. In some towns like Bothell and Bellevue, you can get ticketed if you allow soapy water to flow into the storm water drainsIn Portland many millions of $ were spent to assure that storm water was separated from wastewater (sewer) water. Up until they were separated, much of stormwater was directed to the sewer system. The problem with that was when it rained a lot, hardly a rare occurrence in Portland, the sewer would overflow into the Willamette river. No one wants untreated sewer effluent in the large river that flows thru the middle of their city.
So, yes you are correct. The majority volume of storm water does flow untreated into rivers and streams. I'd say that would be the case for just about all of Oregon too, although I have seen more stormwater bioswales being installed when major road work occurs.
