The legislation permitting control of phosphorus inputs into the aquatic environment From point and diffuse sources is complex and incomplete. River Purification Authorities in Scotland are responsible for the implementation of this legislation, and additionally, have adopted policies aimed at protecting waters from the effects of eutrophication. This paper describes the implementation of the legislation and the policies adopted by the Forth River Purification Board for the control of freshwater eutrophication by reference to the Lake of Menteith. in Central Scotland. The Lake of Menteith is described, the results of a detailed monitoring exercise are presented and the control measures applied are discussed. The Lake of Menteith is classified as mesotrophic. it has a high conservation and amenity value, and is operated as a commercial sport fishery by the Lake of Menteith Fishery Company. The Company operate a fish cage rearing unit on the Lake and two land‐based rearing units on tributary streams. The phosphorus budget for the Lake is described and the implications for future controls discussed.
