If you can get to the mouth of the Osage, try right where the muddy Missouri river water and the clearer osage come together, try to keep your line as close to vertical as possible. I have at times had to use a 1 ounce jig to do this, lift your jig/minnow about 4-6 inches, hold it just off the bottom for 10-15 seconds drop it to the bottom and repeat. Sometime the hammer it and sometime its just a tap. I'd say this method would work at the mouth of any of the larger rivers that feed into the Missouri.
Where do you live Seth?
