Dozens of dead fish have been found floating at the pond at a park in Concord, N.H., and officials are trying to figure out why. Officials said several dead goldfish were found floating on White Park pond last week. Several days later, more fish turned up at the popular park. WMUR-TV reported that the city’s Parks and Recreation Department called the New Hampshire Fish and Game Department and the Department of Environmental Services for advice. David Gill, director of the Concord Parks and Recreation Department, said there is nothing abnormal with the water quality.
