This thesis presents and assesses the 1991 Lake Whatcom Watershed hydrologic model, developed by the author while a graduate student at Huxley College, Western Washington University. The project introduced hydrologic model and geographic information system (GIS) applications for the Lake Whatcom watershed, brought relevant watershed spatial and time series data sets together into a unified structure, and presented quantitative data on each of the major sources and destinations of water in the lake and watershed system. The project successfully completed its identified goals, but was limited by large uncertainties in quantitative values for various elements of the model, notably watershed precipitation and Whatcom Creek flow. These data were the most significant sources of input to, and output from, the lake, respectively. This thesis does not purport to offer the definitive text upon the hydrologic behavior of the lake and watershed. Rather, its value is that it presents an organic system designed to be amenable to future refinements.
