Water availability is important for the company generating hydropower, but is not significant for energy management. Agriculture in the Finnish part in terms of nitrogen load is almost comparable to the natura] background, and, in particular, releases phosphorus (double the estimated natural background). The other sources are clearly smaller, with loading from settlements about 2 tons/year of phosphorus and 33.4 tons/year of nitrogen, and from industrial wastewaters — including peat production and forestry — 2.3 tons/year of phosphorus and 22.8 tons of nitrogen.
