If drought conditions in the area persist, the City of Danbury could tap Lake Kenosia as a water source. But some officials are wondering what other measures could be taken to replenish the reserves.  Councilman Warren Levy brought up at their meeting this month that water was pumped out of Candlewood into Marjorie Reservoir during the Dyer administration.  Jim Dyer served as Mayor from 1979 to 1987.  Public Works Director Antonio Iadarola says in today's more regulated environment, he doesn't see the state ever allowing that.  He says that's why the City monitors water levels and usage on a daily basis.
