WESSINGTON, S.D. (AP) — The rebuilding of a dam in central South Dakota will be delayed by the discovery of an endangered minnow. Officials had hoped to start construction this year on the Rosehill dam in Hand County, about 30 miles west of Huron. The dam failed in July of 2010 during heavy rains. The Topeka shiner minnow was recently discovered in Sand Creek, near the dam. The federal Fish and Wildlife Service lists the minnow as an endangered species. The minnow’s presence means South Dakota’s Game, Fish and Parks Department has to consult federal agencies to make sure the dam project doesn’t affect the Topeka shiner population. Regional South Dakota agency manager Cliff Stone says the dam’s reconstruction will probably be delayed until the fall of 2013.
