Figure 18. Instantaneous yields of streamflow, dissolved organic carbon, particulate carbon, and associated disinfection by-product formation potentials for total trihalomethanes (THM4) and total haloacetic acids (HAA5) for samples collected in the Clackamas River basin, Oregon, 2010–11. (Sites are listed in downstream order. Note the log scale for y-axis in streamflow plots. Loads, in kilograms per day were calculated by multiplying the concentration in milligrams per liter (mg/L) by flow (x 2.447 for units conversion). Yields were derived by dividing the load by the area, in square kilometers. Abbreviations: M, main-stem site; T, tributary; S, source water intake; CR, Clackamas River; CRW, Clackamas River Water DWTP; LO, City of Lake Oswego DWTP; DWTP, drinking water treatment plant.)
