Capacity of Dams Increasing

Dams could collectively hold 13 billion cubic meters of water in the late 1970s, but capacity has now reached 53 bcm, the deputy energy minister for water and wastewater affairs said in Tehran.
There are 193 large dams -- 10 times the number four decades ago, ILNA reported Qassem Taqizadeh Khamesi as saying. The substantial increase is while the population has increased 2.3 times during this period, he said.
Regarding construction of more dams, Khamesi said: “Feasibility studies are underway for 120 dams to add 20 bcm to total reservoir capacity.”
