MISQUAH — A splash reported as “suspicious” near the Bass Lake shoreline drew Deputy Vang out on a quiet Tuesday evening, where he conducted a brief investigation and reached the conclusion that has resolved a great many of the county’s splash-related calls: that it was “likely a carp, a loon, or the usual,” the last category being broad by design.

The call came from a resident who heard, but did not see, a splash of a size and character that struck her as “bigger than a fish ought to be,” a description that covers, Vang noted, “a large fish, a small loon, a beaver in a hurry, or a branch giving up” — the full and unremarkable bestiary of evening sounds on a northern lake. “Water amplifies everything after dark,” he said. “A carp rolling sounds like a body. A beaver slapping its tail sounds like a gunshot. People hear it, and they call, and they’re right to call, because the one time it’s nothing is no excuse for the time it isn’t.”

Vang found the shoreline calm, the water undisturbed, and no evidence of distress, mischief, or anything beyond the ordinary nighttime business of a lake going about itself. He attributed the splash, in his report, to “natural causes, probably finned,” and closed the matter.

Bass Lake, the smaller and quieter neighbor of the Pelicans, produces a reliable trickle of such reports each summer, a function, Vang suspects, of its stillness. “It’s a quiet lake,” he said. “On a quiet lake you hear every splash, and on a quiet lake every splash sounds like it means something. Usually it means a carp had a moment. I drive out anyway. That’s the job — driving out for the carp, just in case it’s not.”
