for PK, shallow is 5-10 feet. In Cedar creek you should be able to sight fish crappie at that depth. When I was catching crappie at PK using a jig and bobber a few weeks back before the fronts my bobber was set at 5 feet deep.
For every crappie I caught 5 bass. Some of them were whoppers.
John 21:3 Simon Peter saith unto them, I go a fishing. They say unto him, We also go with thee.
