The new or still existing, but in much higher concentration now, problem is the run off from farms in fertilizer and the treated waste from animals and humans. These are the out of sight out of mind things that can build up to cause problems. Sometimes we hear of untreated run off kills like this one in the Thumb:
CROSWELL, Mich. (AP) —A judge has ordered a Sanilac County farm to pay $75,000 in penalties for a 2009 manure spill that killed more than 200,000 fish in the Black River near Croswell.
The Times Herald of Port Huron reports (http://bwne.ws/GXX4hi) Sanilac County Circuit Judge Donald Teeple ruled Monday on the payout from Noll Dairy Farm Inc.
The Michigan Department of Natural Resources cited Noll Dairy Farm as the source of the contamination. The runoff flowed into a creek that feeds the Sanilac County river. Smallmouth bass, catfish, northern pike, rock bass, sunfish, suckers, minnows and darters died after the spill.
A message seeking comment was left Wednesday by The Associated Press at a listing for the farm, which has said the discharge was accidental.
Nearly 20 miles of the river was affected.
If the run off was treated you wouldn't hear anything but the "nutrients" make their way to the Great Lakes and Lake Erie is a catch basin and where the blooms are evident. This is another sign and one of which points to over crowding.
Along those lines is the Detroit River Clean-Up on April 28th. Anyone interested in helping with or without a boat should meet at the Rotary Park in Trenton at 9 am. Bring gloves and dress for the weather, life jackets are needed if you have them. For more info go to www.detroitriver.org
