The severity of this past winter has left its mark on the shorelines of ponds and small reservoirs throughout the state.
Dead fish, thousands upon thousands of them, have washed up along banks during the spring thaw, falling victim to a lack of dissolved, life-sustaining oxygen in the water. State environmental officials say that the long winter's thick, snow-packed ice proved an effective barrier to both air and light. Not enough light reached below the surface to allow adequate photosynthesis by aquatic plants and algae that release oxygen.
Winter fish kills are a natural phenomenon, but the unusually harsh winter caused them to be widespread and, in some cases, more devastating than in past seasons.
"I had never heard of anything like that before. It was a surprise to us," said Kathleen Bagley, director of parks and recreation in Wethersfield, where thousands of dead bass, bluegill and sunfish have carpeted portions of the shoreline at the 1860 Reservoir.
Winter kills have been reported so far at 36 lakes and ponds, according to the state Department of Environmental Protection, with most of those reports coming in the last two weeks of March, when warmer weather took hold and surface ice melted. Source
