After a record-setting 107-fish day earlier this month, solid Atlantic salmon returns have continued at Milford Dam, according to marine resources scientist Jason Valliere of the Maine Department of Marine Resources. In a regular email report that he filed on Tuesday, Valliere said the total number of salmon counted at Milford had reached 597. “Looks like we are having the best salmon year since 2011,” Valliere reported, referring to a year when salmon were still being counted at the Veazie Dam farther downstream.
