Eastern parts of Connecticut are at a “very high” risk of forest fire on Monday, state officials said, after weeks of drought have plagued much of New England. In Redding, fire officials said they battled two major brush fires over the weekend, including one blaze along the Saugatuck Reservoir. The blaze is under investigation by the state Department of Energy and Environmental Protection and Aquarion, the water company that controls the reservoir. Redding officials are asking people to be “extra vigilant” when discarding any smoking materials, and said any kind of outdoor burning should be curtailed. “These are very dangerous and resource-depleting operations,” Redding Fire & EMS Company No. 1 said in a Facebook post Sunday. DEEP, which issues the state’s daily forest fire danger report, said the risk of forest fire in the eastern counties.
