An Investigation of the Boardman River Biota in Response to Temporary Drought Conditions

Grand Traverse County
On May 22, 1981, the Brown Bridge Dam spillway gates were accidentally closed and remained closed for approximately 1.5 hours. This closure stopped the discharge at Brown Bridge and lowered the downstream river level* exposing portions of the stream bottom to the air. This investigation was done to determine the effects of this temporary "drought" condition on the river’s benthic invertebrate fauna, with special consideration of fish food items. Item includes Addendum dated July 13, 1981.
