GASCO
GASCO is a former manufactured gas plant which deposited wastes into upland tar ponds for many years. The site is located near river mile 6.5 between the St. Johns and Railroad bridges on the southwest side of the Willamette River. The tar ponds overflowed into the Willamette River for decades. The overflow remnants were visible at low river stages of late summer and early Fall and were eroding. Removal of the in-river tar deposit was completed in the Fall of 2005 (brown material in the picture at the right).
