Maine's Red Quills

“Red quills often emerge on the Sheepscot on an exact date, May 7, dependent on water temperature. When a spring produces normal weather that raises the water to 52 to 55 degrees, I feel quite certain that red quills will start popping to the surface at 2 p.m on the appointed day.” Ken Allen disects the arrival of the Red Quills on Maine rivers on MaineToday.com.
