We started keeping records in 1986 but they were a little vague back then! In 1991 Debbie started buying me the Sports Illustrated Swimsuit Calendar. For obvious reasons I started keeping better records. So to answer your question we think the latest Spring was 1990.We could boat from Keewatin to South end of Scotties Island,South of this area all the way to Queer Island was solid ice on May 05.We tried Manitou and it was solid ice as well,boating down to French Narrows a week later. Here are a few years/dates we made it to Bare Point from French Narrows.April 16/2006,May 04/2007,May 09/2008,May 06/2009,April 14/2010,May 04/2011,And last year was earliest on April 10. We will be making another quad trip to town this week for fresh produce.We rec'd 1.5" snow by noon today and its been snowing all afternoon but melting on impact.
