Impact of Dam Construction
The Damodar was once an endemic flood-prone river. The Maithon and Panchet dams, constructed in 1957 and 1959 respectively, have significantly reduced daily and annual discharge and also largely eliminated the extremes of flow so that ten-year recurrence interval floods have been reduced to half. Sediment trapping in reservoirs and the lack of flushing due to reduced peak discharge have inevitably transformed the lower Damodar basin into an ecologically imbalanced area.

Famous quotes containing the words impact of, impact, dam and/or construction:
“Television does not dominate or insist, as movies do. It is not sensational, but taken for granted. Insistence would destroy it, for its message is so dire that it relies on being the background drone that counters silence. For most of us, it is something turned on and off as we would the light. It is a service, not a luxury or a thing of choice.”
—David Thomson, U.S. film historian. America in the Dark: The Impact of Hollywood Films on American Culture, ch. 8, William Morrow (1977)
“Too many existing classrooms for young children have this overriding goal: To get the children ready for first grade. This goal is unworthy. It is hurtful. This goal has had the most distorting impact on five-year-olds. It causes kindergartens to be merely the handmaidens of first grade.... Kindergarten teachers cannot look at their own children and plan for their present needs as five-year-olds.”
—James L. Hymes, Jr. (20th century)
“The devil take one party and his dam the other!”
—William Shakespeare (1564–1616)
“When the leaders choose to make themselves bidders at an auction of popularity, their talents, in the construction of the state, will be of no service. They will become flatterers instead of legislators; the instruments, not the guides, of the people.”
—Edmund Burke (1729–1797)
