As for the cleaning station: I sent an email to Weaver's Tackle store, located just outside the park, and here is what they had to say:
The Hatchery Manager stopped by for a visit a week or so ago, and we asked about the cleaning station. It is still "in progress", but the engineer who is designing it has been pulled off the project for a "higher priority" job.
While it is still in the plans, there is now no estimated time for construction (at first, it was going to be completed by March 1 of this year). Apparently, there is some disagreement between the Dept. of Natural Resources and the Missouri Dept. of Conservation as to how the waste will be handled.
That's all we know at this time . . . the hatchery manager believes it will still happen, it's just a matter of when and also dependent upon the resolution of the waste question and releasing the design engineer to get back to work on the project.
Let us know if you need more information or have more questions.

Hope this helps a bit.
