I added a new link on the resources page for the Maryland DNR’s Trout Management Map, a clickable map of locations stocked by the state. Check it out.
Pennsylvania has a great interactive map showing the state’s fishable waters, with stocking info, directions and more. You can filter for Class A wild trout streams, stockable rivers, the whole bit. It also shows what percentage of each stream has public and private access. Very, very cool and useful. Will come in handy this spring and summer when I travel up there.
