Table 13. Principal component scores at sites Eagle Ridge and Midnorth in Upper Klamath Lake, Oregon.
[Water-quality data are biweekly values of chlorophyll a and nutrient concentrations, and biweekly profiles of dissolved oxygen concentration collected by the Klamath Tribes at two sites in Upper Klamath Lake during July and August, 1990–2004. Concentrations: ∆DO: difference between water column maximum and minimum dissolved oxygen concentration. Water column temperature: ∆T, difference between maximum and minimum water column temperature]
