Welcome Steve, in case you haven’t seen this video I’ve attached below, it gives you a great idea of what its like at lower water. I checked the guage for 2013 and 2014 and in 13 we had a sizable rain during the first week of June and it was runnable but last year it was only runnable the second week of June. I’d keep watching the gauge before you leave and ask what the veterans think if it will be boatable. Its all depending on the amount of rain of course. I’d paddle with you mid week if you decided to bring your boat since I only work 30miles away. There are plenty of people that drive from StL for a day trip. There are two ways to know if its runnable and worth the drive by looking at the top of this forum page and make sure its 0″ or above or keep an eye on this site: http://waterdata.usgs.gov/mo/nwis/uv?07034000 and make sure its above 3 foot.
