  Citation × Citation Citation Abstract Copy Title: Pend Oreille River, Box Canyon Model: Model Scenario Simulations Author: Berger, Chris, Annear, Robert Leslie, Wells, Scott A. Year: 2007 The Washington Department of Ecology is interested in developing a temperature Total Maximum Daily Load (TMDL) allocation for the Pend Oreille River between the Albeni Falls Dam (U.S. Army Corps of Engineer’s reservoir) and Box Canyon Dam as shown in Figure 1. The Pend Oreille drainage basin is shown in Figure 2. An existing model of the Box Canyon reach was updated from CE-QUALW2 Version 3.0 to Version 3.5. This current research involves improving the calibration of the original model (1997 and 1998) and expanding the model using 2004 as an additional data set for calibration. The use of field data from 2004 as an additional calibration year was chosen to improve the confidence in the model’s predictive ability for temperature. Hence, the model simulations were run from January 1st to December 31st in each of the 3 years of model simulation: 1997, 1998 and 2004. The model chosen for development is CE-QUAL-W2 Version 3.5 (Cole and Wells, 2006). This is a twodimensional unsteady hydrodynamic and water quality model that includes typical eutrophication parameters (algae, nutrients, temperature, organic matter, dissolved oxygen, pH). The PSU-WQRG (Water Quality Research Group) is a center for development of this modeling tool (see http://www.cee.pdx.edu/w2). The model simulation for scenarios was run from January 1st, 2004 to September 25th, 2005.
