Abstract The design and application of the Lake Condition Index (LCI) system of classifying lakes is described, and it is demonstrated that lake classification can be employed as a useful tool by resource managers for comparing the trophic condition of large numbers of lakes. The LCI system was generated when an evaluation of other systems revealed that most are presently unsuitable for classifying the vast majority of lakes because the analytical data required for their use are lacking. Utilizing subjective information, the LCI system was applied to the classification of more than 1100 large Wisconsin lakes. Checks of the results show that 86% of the lakes were appropriately classified within the limits of the system; 14% were misclassified, as judged by individuals familiar with the lakes in question. Most, but not all, discrepancies were due to erroneous input data. The LCI values obtained were coupled with nutrient-loading considerations and shoreline density-development factors to demonstrate that lake classification can serve as a workable data base for lake renewal and management programs.
