Most anglers show up at new water, pick a spot and hope. This short tip from the Fly Fishing Insider Podcast argues for doing homework first, and the good news is that it is easy. The idea of a secret spot hardly exists anymore, so there is almost always information to find. Here are the research methods from the episode, plus how I put them to work.

Start with the internet and maps
The internet is the first resource. Search the area and specific named holes or access points, then open Google Maps and switch between the map and terrain layers. Seeing bends, riffles, braids, lake points and road access from above helps you pick a few places to check, and it lets you make a plan for a backup if your first choice is crowded.
Call the local shops
Phone the shops near your destination and ask specific questions: where you plan to go, where fish are holding, where you would be alone, what the fishing is like and which techniques are working. Shops exist to help. The tip also recommends returning the favor by stopping in, buying a few flies, and giving them a shout on your social channels if they helped you.
Ask people on social media
Social media is rich in information. Message friends or ask guides directly whether they recommend the spots you are considering. Because you already have a short list from your maps and calls, your questions can be detailed, which gets you detailed answers.

Don't forget the library
The last resource is books. Your local library, and many online sources, offer free guides and regional fishing histories that can fill in the details websites skip.
Putting it together
A simple routine: spend an evening on maps and write down three spots, call a shop in the morning, message a guide or friend to verify, then read about the water. Take notes on access, season and recommended flies so you can build on it each trip.
Gear
Once you know where you are headed, the Tips and Tricks for Fly Fishing eBook helps you pack and rig for the day, and the FFIP Logo Anglers Coffee Mug is a good companion for the early drive. For flies matched to that water, the local fly shop you called is the best stop.
