There are three artificial lakes, created by damming of tributary streams during community construction. This included increasing access to groundwater, and creating lakes by damming rivers. Plans will include methods for damming gullies and reducing rainwater runoff. Submerged forests exist on land that has been flooded by damming to create reservoirs. Grander schemes of damming and redirecting rivers should also be considered if possible. Great Sacandaga Lake is a reservoir created by damming the Sacandaga River. Cedar Lake is an artificial lake formed by damming Cedar Creek. The lake is a reservoir created by damming the Pecan Bayou. Indiscriminate damming along the river has been cited as an obvious reason. Early ranchers preserved water by damming canyons and draws to hold the heavy spring rains. A reservoir is located southwest, damming up the Alfeios River. The period saw sixfold increases in water use and river damming. Instead of completely damming the estuary, the government agreed to build a storm surge barrier. This led to the eventual damming of nearly every major western river. Damming by beavers creates suitable breeding sites.
