Gentlemen I can help greatly with your NSR issues....
There is so much rapid change in the sediment or sand where whitemud creek enters the NSR, therefore the "holes" or "pools" change as well.....if you are after catching anything there try a little further out from the mouth if you are downstream of the creek cast 20-30 feet out and let your bait sit.
As for bait you best bet is Dew worms on a pickeral rig with the bottom hook at least a foot to a foot and a half off the bottom. Don't just fish at the creek mouth about 20 yards down to i guess 30 yards downstream of the creek mouth about 20 to 30 feet out there same thing try dew worms... If you are planning on using minnows or smelts use the exact same set up and cast slightly closer to shore....the key with whitemud is patience and experience.....you can only gain experience with patience.
There are many tricks with catching at the creek but it also depends on the habitat at the time you go. Spoons and other lures do sometimes work but its based on the Angler using them and the time they choose to fish. We all fish slightly different ways and fish at different times.
Try a jig with a minnow, cast it into the pool of the creek and slowly retrieve it......if after say 30 casts nothing try a pickeral rig and still fish in that spot........after 20 mins if no bites or nothing try worms....same thing and then just keep moving down stream......don't cast out crazy far...just enough to get your bait 20 feet or so.
These are from this year on the NSR
