Thanks for the information. It is good to see facts then people just going back and forth saying that is the right way. This is scary when think about how bad Lake St. Mary is. I know that the water probably loses some of phosphorus etc. through its travels but when you consider that there are alot of farms along the maumee as well and you combine the phosphorus from St. mary's plus maumee, this creates a substainal problem. Thanks again for pointing this out.
