IMHO, I would think your chances are very good, considering you mention that there is a creek channel.
If there is an incoming current (I'm not sure if that's the case, but it's worth mentioning) which is warmer than the rest of the lake, then you should be able to get em pretty good. If the incoming water is colder, then I wouldn't spend a great deal of time there. One other thing, if the incoming water is bringing in a lot of silt and is temporarily muddying the water, then the bite could really slow down.
Good luck either way.
