Description This technical memorandum summarizes work CDM performed under Washington State Department of Ecology (WDOE) Contract No. C0800239 with the Washington State Department of Ecology. This work includes five scenario simulations using the calibrated Lake Whatcom HSPF model for full build out and natural land use conditions (Cadmus & CDM, November 2007) and the original model for Existing conditions (Cadmus & CDM, July 2007). The five scenarios are based on a reduction of land use classes from the Existing and Full Build Out scenarios. The additional scenarios were used to develop estimates of the Total Phosphorus loading into Lake Whatcom and as inputs into WDOE’s Lake Whatcom CEQUAL-W2 lake model. A primary objective for running these additional scenarios in the HSPF model were to show what additional burden must be placed on existing development to accommodate future development.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
