Here in Pa, we have to get permission from the COE to put habitat of any kind in the water. We also have to notify them of where we plan to drop it. Our lakes are used for flood control so they are raised and lowered as needed. They use these lakes for recreation as well as fishing so they don’t want us putting it in areas that the recreational boaters use as when they lower the lake our habitat may pose a problem/ danger to them. Our COE drops habitat every spring in areas they deem safe. They have maps available with where they put them for free. Some people still drop their own tho. Most times it’s in the deep river channel. Twenty feet or more deep.
