What year was The Teenagers Dike created to help save downtown Stillwater from flooding?

Heavy rain and snow runoff raised the St. Croix River above flood stage in 1965. Residents, students and even inmates from the Minnesota Correctional Facility came together beginning April 10 to build a dike to save downtown Stillwater. There were so many teens helping fill sandbags, there was a sign naming it The Teenagers Dike. By April 15, government officials closed off downtown to foot and vehicle traffic. The River crested at 694.07 feet above sea level on April 18. The Teenagers Dike held fast! Downtown reopened April 21. You can see still the sign at the Washington County Historical Society (

What building served as Stillwater’s first reading room and public library?

The Jassoy Building
Immediately west of the junction of Chestnut and Third Street is the Jassoy Building, built by Theodore Jassoy in 1886. He and his son Herman owned and ran one of the finest harness and saddlery shops in Stillwater and in the state.  The building, known as the Jassoy block, housed the family on the second level of the building with businesses on the first and a meeting hall for the Stillwater Lodge No. 7, Knights of Pythias on the third. In a blurry photo of the building taken in 1898 (not shown), the southernmost window of the lower level has the words “Public Reading Room” inscribed. The year the photo was taken was the year the first Board of Directors of the Stillwater Public Library was formed and had their initial meeting in August. At this meeting, it was moved that the first floor of this block ‘will be leased for a term of 3 years at a rental of $50 per month’ from Jassoy for use as a library, with the understanding that the rooms on the first floor would be connected and supplied with additional lighting and adequate heat. This was the inception of the library that has transformed into what we now have today.
