Is The Columbia River at Marine Parka safe place to play in the water?
The Columbia River
The largest river in the PNW, 4th largest in the U.S.
1,243 miles longIt is a seventh order stream It is central to our region’s economy and
culture, and has been for centuries14 dams provide hydroelectric power to the
region
My Testing SiteMarine Park - Lewis and Clark expedition camped
here on March 30, 1806. - Now it’s a 26 acre community park with
a boat ramp, play area, picnic tables, and walking trails.
- Diverse wildlife population, supporting several species of water fowl, including bald eagles, osprey, herons, and Canadian geese.

Is the Columbia River safe for human contact? According to my results, YES!The pH, phosphate, nitrate, dissolved oxygen,
turbidity, and coliform bacteria all point to a healthy aquatic
environment.
