The stocked lakes are refered to as "trout management lakes" not "trout management areas" so I would not think that you would need a trout stamp on the stocked lakes and ponds. Rivers and streams are refered to as "trout management areas" and would need a stamp for these areas. So if I just fish lakes and ponds I interpret this as not needing a stamp.???? Very confusing!! So we are hit with another "tax" because I want to keep a trout. And yet the state cuts back on the stocking.
