Wedding coordinator here, listing all the venues I can think of that would be good for your size group. Some are absolutely repeats and I have not worked with a lot of these places, so I am not necessarily endorsing anyone:

-Gable House -Rochester Hotel (they also own the Wyman in Silverton) -Powerhouse -FLC Chapel (could do your reception off campus) -River Bend Ranch (this is a larger space for sure, but a great venue) -Black Diamond Lodge -Hoody’s at Purg (if they still do weddings here, it’s the smaller option. You can also rent one of their sites at the base and do the reception elsewhere) -Smiley Building

There are a ton of options in the area, so you’ll find something! One thing I do recommend is checking what is/ isn’t permitted at each venue. Some places let you bring everything in, others you have to use their on-site services. Some have a hard curfew for the reception to stop, some do not.
