We are investigating how water quality indicators change along the course of Noyes Slough. Noyes Slough (Ch'exongw Notodh'ode in the Lower Tanana language) is a winding side channel of the Chena River that flows through a significant portion of Fairbanks, Alaska. Reduced sediment flows in the Chena have caused the river to deepen and narrow its channel, partially cutting off Noyes Slough and causing it to become relatively stagnant. This has made it more sensitive to point-source pollution inputs. We aimed to determine whether the water quality of Noyes Slough diminishes along its length from upstream to downstream. We were curious to see which sections of the area have been affected most by development over the last 50 years.
