I exchanged emails with the St. Charles visitors center. Their reply follows:
There is not an official overnight parking lot for vehicles for visitors using the Katy Trail starting in St. Charles -- most trail users park in the Lewis & Clark Boat House and Museum parking lot located right by the Katy Trail. Here’s a detailed Downtown St. Charles Map:

(you’ll see the parking lot located at the bottom of map by Lewis & Clark Boat House)
We just recommend that you notify our local City of Saint Charles Police Department with the make/model of your vehicle and the dates you will be parked in that lot – here’s their number: 636-949-3300. Lots of folks will do this and there is not a problem with doing so.
Enjoy your trip - we are starting tomorrow!
