Drawdown at Children's Lake to Kill off Nuisance Plants
The Pennsylvania Fish and Boat Commission recently lowered the water level at Children’s Lake to control vegetation growth.

Lowering the water level exposes aquatic plant life to the cold air causing it to freeze and die off, township supervisor Tom Faley said. He added there are places where the water level is down by as much as 75 percent, prompting water fowl to walk on the lake bottom or swim in puddles.

Aquatic plants provide very good habitat for both young and adult fish, as well as aquatic insects. However, too much vegetation can negatively impact fishing and boating opportunities and has the potential to disrupt the balance of fish population in a lake.

Lock and Dam Changes Aimed at Stopping Invasive Carp - Bighead, silver and other invasive carp have been making their way upstream since escaping into the Mississippi River in the 1970s. These large fish are voracious eaters that compete with native species and pose a threat to rivers and lakes. While no breeding populations have been detected in Minnesota waters, individual fish have been caught in the Mississippi near the Twin Cities, the St. Croix River and the Minnesota River.
