(Missoula Current) The dam at the head of Placid Lake is leaking water, prompting state officials to remove a boat dock and work with the dam's owners on repairs. That has caused the water level in Placid Lake to drop, impacting some forms of recreation. That includes the six-slip boat dock, which FWP planned to remove. Wildlife officials said the dam also creates a natural barrier between non-native fish, like northern pike and smallmouth bass, that exist some areas downstream of Placid Lake. To keep it that way, FWP may install a temporary fish barrier until repairs to the dam are complete.
