Little Rock Lake

A landmark study on acid rain came to an end today.  Researchers took down a barrier that’s divided Little Rock Lake in two for nearly thirty years.  Dismantling the curtain was no easy task.

Decades after scientists proved the effects of acid rain on northern lakes, it was time to take down the Little Rock barrier that made the study possible.  Fifteen researchers, students and divers were on hand for the challenge:  how to dismantle a 250-foot curtain…made of heavy black plastic, and partially submerged under years of sediment.
