Lake Filter Called OK

ADULT MINNOWS State officials are trying to find out how adult minnows got into the open channel below the outlet's rock-and-gravel filter system. The filter is supposed to prevent the transfer of adult fish and other smaller organisms that Manitoba officials worry will pollute their water systems. The outlet drains Devils Lake floodwater into the Sheyenne River and ultimately the north-flowing Red River. http://www.winnipegsun.com/News/World/2007/06/24/4285781-sun.html
