UPDATE: Dam fails jeopardizing homes
Water rushing through the Bark River Dam at Nagawicka Lake has caused the failure of a downstream dam and is causing water to rise to dangerous levels on Upper Nemahbin Lake in western Waukesha County, Summit Police Chief James Race said.Six Upper Nemahbin lake houses have been evacuated and another 12 would be in jeopardy if water keeps rising, Race said.
County Highway DR has been closed between Waterville Road and the Bark River because of standing water,18 inches deep in places, caused by the dam failure. Interstate 94 is not in jeoopardy, Race said.
The DNR is at the dam site attempting to block the millrace and slow the draining of the millpond at the Nemahbin Roller Mill Dam .
The dam formerly served a grist mill and later was used to generate electricity, is owned by resident Margaret Zerwekh, who recently petitioned the DNR for permission to abandon the dam. Her neighbors have sought to keep the dam in place to preserve the millpond on which they live.
