Abstract This report presents one methodology to classify natural lakes with respect to nutrient processing. Lakes in the Coast Range Ecoregion were inventoried and lakes greater than 4 ha in surface area were chosen as the target population. A methodology was then developed based upon expert opinion to categorize lakes in the ecoregion based upon basic limnological principles. The categories were developed without recourse to nutrient data. Analysis of total P, total N, chlorophyll and Secchi was carried out for (1) the Coast Range lakes as a whole and (2) for each lake category. Results suggest that these parameters have inherently different variability among lake categories which affects their utility in developing numeric nutrient criteria.
