Wading
Wading is a good way to get to fish in shallow water and can be the best way to fish for some species, like trout, in streams. But you must be careful. Getting into the water adds some danger to fishing, from slipping and hurting yourself to dropping tackle and losing it. But it's worthwhile if you're careful.
In warm water you can wade in shorts and tennis shoes but cold water requires waders (waterproof pants with boots attached) that will keep you dry and warm. Walk carefully and fish going upstream, casting to places holding fish ahead of you. That way you won't spook them by stirring up mud and debris that will float over them. In still waters walk carefully and slowly or you'll scare the fish.
Hip waders come up to your hip and chest waders come to your chest. Both are held up with straps and keep you dry while wading in cold water. You can wear insulated pants under them for even more warmth.
A long stick is often used to help brace yourself while you wade. You can fish with any kind of rod and reel, but a fly rod is traditional. And wading gives you room for your back cast when using a fly rod. Give wading a try if there are suitable waters near you, but be careful.
