The Lake County Leader is one resource for news and events in the Ronan and Lake County area. This is a good place to get local news, and the events calendar can be found under the pull-down tab of Home/News.
Polson and Ronan function in many ways as one large community. Many events in Lake County occur in the Polson area (especially in the summer). The calendar that can be found on this website is a good way to find events in the community (see "things to do" on the left hand side of the page).
