Contents Notes
"EPA Region 10 is developing mathematical models of water temperature as decision support tools for watershed planning in the main Columbia and Snake rivres. This work has been primarily for the purpose of developing a Total Maximum Daily Load for thermal energy as required for water-quality limited river segments under Section 303(d) of the Clean Water Act... Dworshak Dam and Reservoir on the North Fork of the Clearwater River in Idaho is upstream of the four run-of-the-river Snake River dams... Because Dworshak Dam can provide downstream temperature control, it plays an important role in watershed planning for the Clearwater, Snake and Columbia rivers... This report represents a preliminary effort to assess the effectiveness of the two-dimensional mathematical model, CEQUAL-W2, for this purpose..."-- p. 1 Introduction.
