Warmer weather doesn't mean warmer water. Days are getting longer and slowly rising water temperatures should get fish to bite.
The Potomac remains in the mid 30s! NBC Ch. 4 meteorologist "Weather Kim" Martucci says, “After Monday's mid 30s, a big warm up is on the way, highs in the upper 40s to start, near 60 to end the week. Cloud cover brings a chance of rain heading into the weekend. Overnight lows in the upper 30s or higher.”
Fishing slowly is key! Find the warmest and clearest water which should be an outgoing tide on the north end of the river. At warm water discharges, try suspending Lucky Craft Pointer 78 jerkbaits. Otherwise for the rest of the river, burp Silver Buddy 1/2-ounce lures on 8-10 pound test GAMMA Edge fluorocarbon line slightly off the bottom or slowly drag with frequent stops! Slowly lift and glide or drag and stop Mizmo 4" chartreuse curl tail grubs and Mann's 3" avocado Stingray Grubs on 1/4 ounce or less ball head jigs with 6-pound test on spinning gear like Quantum EXO combos. Allow Punisher hair jigs with Punisher rattles to sit and shake, trying to leave in one spot for a while. Try a plastic or pork chunk to add bulk and to slow the movement.
Soak baits in garlic flavor Jack's Juice! This is really important when using hair jigs. This bait spray soaks into the plastic or the jig hair fibers. Gel or oil products will prevent the hair from breathing, a key to success
Start shallow and work deeper in areas out of the current with steep rather than gradual drops. If you think you are fishing slow, slow down even more!
