Photo by Kathy Gravino WOOLWICH — As spring comes to coastal Maine, it brings with it the return of alewives to Nequasset Lake and the start of the annual “Nequasset Alewife Count.” Sign up for a count online at kennebecestuary.org/fish-counting. Each fish counter signs up for a two-hour block and counts fish for two 10-minute periods in that block. Counting is broken into blocks between 6 a.m. and 8 p.m., every day of the week for the month when the fish are climbing the ladder to go into the lake.
