A Pennsylvania Power & Light crew works Friday to raise flashboards on the Milford Dam. Dick Fennelly, manager of generating assets for PPL Maine, said the hinged steel plates are used to maintain a certain water level above the dam, thereby creating maximum generating power for the company’s hydroelectric turbines. The flashboards are designed to let go when the water rises to about 2 feet above the dam level, which happened recently because of all the precipitation the area has received. Fennelly said the crew hopes to finish resetting the flashboards in the next few days, but it is a slow process. The crew can raise only a few each day, then let the water level drop a little to make the work safe. The work may be hampered by the weekend weather, which the National Weather Service forecast would bring a wintry mix, from snow to sleet to freezing rain as the temperatures rise from southern to northern Maine early Saturday morning to Saturday afternoon. A winter weather advisory was to be in effect from 6 a.m. to 3 p.m. Saturday in the Bangor area and from 6 a.m. Saturday to 2 a.m. Sunday in the northern part of the state. Up to 2 inches of snow and a tenth of an inch of accumulation were expected.
