I'm planning on going Snakehead fishing in the Potomac Creek here soon and would love a few tips for those who are experienced. I've read in some previous posts that receding tide is ideal and a chatterbait or frogs are the best option, so I plan to build on that. If picking an ideal time based on tide is not possible, what do the fish tend to do during low tide and when the tide is coming in? Does size matter for chatterbaits, seems like people say they have smaller mouths. Beyond that, the plan is to fish the small grassy/padded creeks, are they strictly in shallow water near these thick vegetated banks even in 90 degree summer heat? Thanks for the help.

Snakeheads like overhead cover - so pads and spatterdock are better than grass, but they like matted grass too. Falling tide on the outside edge of cover is best, but at low tide they have less cover so holes in matted grass, overhanging trees, etc should get it done. If they wont come up for frogs, a swim jig or bitsy flip with a rage craw on it was my next best. Pitch or swim it close along matted edges and in holes, or through the weeds. 

Catch every snake head you can and have a fish fry - I hate those things !

They are delicious!
