If you're a PA angler, or figuring a trip here to do some trout fishing this year, you can tell when your favorite stream will be stocked. The list is searchable by county. If you're not certain the county of your favorite streams, the Commission has maps of the state that can show you everything you want to know.
You can see the stocking list HERE.
You can read all about getting a fishing license & all the regulations on their website HERE.
I would recommend that you read the section on the fishing regulations, as there have been changes made to the trout season this year, in response to the pandemic. For example, the season is starting earlier this year, so the open waters will be closed a little earlier, too. This, & other changes, you need to be aware of before you attempt to wet a line in PA this season.
Spring is coming!!!.......& it won't be long before we can all enjoy the hatches, the fish, & the beauty of a trout stream in spring!!
