What is the importance of lakes in the economy?

First of all, lakes are used as reservoirs – for each nearby settlement, such reservoirs are strategic reserves of fresh water, used primarily for domestic needs. In addition, the water of such reservoirs is used in agriculture, since it is impossible to obtain crops without sufficient moisture. Large lakes are used for shipping purposes, and passenger routes are developed on them. Fish is always caught on such reservoirs, and there are also tourist activities.
