Workers drain dam, beavers repair
Massachusetts Highway Department officials said a pair of tenacious beavers used mud to clog a plastic pipe inserted into their dam to drain a flooded road.
The department said workers initially used backhoes to breach the dam in wetlands next to Den Rock Park in Lawrence, but the animals quickly rebuilt the barrier and flooding resumed on Route 114, the Boston Globe reported Tuesday.
The officials then inserted the plastic pipe into the dam to allow the water to flow away from the road, but the beavers used tree branches and mud to clog the makeshift drain system.
Adam Hurtubise, a spokesman for the Highway Department, said workers have now constructed a cage around the pipe to keep the beavers from tampering with it.
"It's certainly not uncommon to have to breach a beaver dam multiple times,'' he said.
