Jake,
I forgot to mention thermacare or flexdal 454 is commonly used for sore muscles. I have used it after cathing all those fish, but in your case it will work for casting all the time oh and sun block.
Here are some keys that you can try next time.
1. Look for carp, This seems wierd, but I have seen this every time I am on the spots with walleye. A theroy that one of the club members said ” that the walleyes are in there eating the carp spawn” I don’t know how true this is.
2. In the dark and stained waters that we have right now we used the blue and chrome and fire tiger colors. Any thing that would give off a flash or is bright colored work.
3. We started off using #5 shad raps and found that the water was higher than normal, so we swithed up to #7. Try to keep the cranks in side the 2 foot range off the bottm. I picked up the Rapala trolling and casting guide to figure out what would work the best.
4. During low light conditions (like yesturday morning) we found the fish in shallow water less than 2ft, but as the clouds broke up and the sun hit with out wind the fish moved in the same area in 5-7 ft, but as the winners said ” as the wind came up the area they fished turned on again” throughing cranks into shallow water.
Jake I hope this helps.
