Figure 1(page §) provides a general map of Lake Whatcom and its tributaries,and shows the current lake sampling sites. Refer to Appendix A, Figures 190–192(pages §–§) for detailed maps showing lake sampling locations.
Figures 2–51(pages §–§) show single-day Hydrolab profiles from Lake Whatcomfor the February and September sampling dates.
Figures 52–71(pages §–§) show multi-year plots of Hydrolab data for LakeWhatcom. The lines connect data from a single sampling depth through time tohelp identify seasonal patterns of convergence and divergence; however, they donot represent continuous sampling. The minimum and maximum values representonly dates actually samples, not the annual extremes. Missing values were notinterpolated.
Figures 72–75(pages §–§) show correlations between date and dissolved oxygenduring the summer at Site 1, 12–18 m.
Figures 76–140(pages §–§) show multi-year plots of water quality, chlorophyll,plankton, and Secchi depth data for Lake Whatcom.
Figures 141–155(pages §–§) show multi-year plots of coliforms and Enterococcusdata for Lake Whatcom.
Figures 156and 157(pages §and §) show iron concentrations in untreated drinkingwater (gatehouse) and average trihalomethanes concentrations in the Bellinghamwater distribution system.
Figures 158–166(pages §–§) show the hydrograph data and rating curves fromAustin, Anderson, and Smith Creeks; the water balance figures; and a summary ofthe Middle Fork diversion.
Figures 167–175(pages §–§) show sampling locations for the Park Place andBrentwood wet ponds and the South Campus storm water treatment facility, currentphotographs of each site, and multi-year inlet/outlet concentrations for selectedcontaminants.
Figures 176–189(pages §–§) show the field and laboratory quality control resultsand Hydrolab quality control comparisons.
