i live in sw michigan.i had the front of my pond dredged out , got the permit from the deq .they have a 7 year limit as to when they can check on the job done and see if it meets their standard.they are very powerful people and i don't like dealing with them i am glad the 7year period is over with. they don't tell you when they are coming to look at the site they just come.they act like they own it.muskrats are destroying my banks now ...it is getting to be a mess
