Notes

River is usually low here at this time as they open the dam to help the water escape from above ( it's very narrow where the train bridge crosses below Arnprior) Now; the river level is higher than normal and the water is flowing fast. Cormorants and seagulls are common sights as are Canada Geese (with babies). A beaver was on the shore a few weeks ago.
