The chironomid communities of fifty lakes in northern Norway are presented and briefly described. A limnological classification of the communities is given, together with remarks on the methods used. The interrelationships are given of the chironomid communities and such lake‐water parameters as the minimum oxygen content, Secchi disc values, conductivity, total hardness and calcium content, total nitrogen, total phosphorus, chlorophyll a, and estimated fish yield. The best predictive and monitoring value of the chironomid communities, as classified by the above system, was obtained for the organic parameters. Compared with other indices used for estimating fish yields, the present method is as reliable as the better ones.
