Lost Our Home on the River: Please Help

We owned the boathouse under the bridge. We were living on the boat and have for about a year now. The snow was coming, so we stayed with family during that time. Then it started flooding, and the flood and river took our boat down the river and demolished it. Everything we owned was on that boat. We have literally one outfit apiece, maybe. We're trying to rebuild now and just need a little help getting there.
