Iran has numerous large and small rivers but still not enough water for irrigation. the water for some streams pours into the dry central plateau and goes to waste, and great efforts are being made nowadays to control and gather this water behind large and small dams. Iran’s major rivers are the Atrak, the Sefid, and the only river that can be navigated – at least over parts of it- the Karoon. land5.gif (47036 bytes)Iran’s other rivers include the Zayandeh which passes through Isfahan; Karkheh and Jarrahi (south-west); and Zarrineh which flows into the Lake Urumiyeh (northwest).
