Susquehanna River "kayaking" Mike, Corey and Jim took a Trip down the Susquehanna River from Duncannon to Marysville on the Susquehanna River in Pennsylvania. We had a good trip down the Susquehanna River today. The Susquehanna River gauge at Harrisburg was 3.18 feet. The water temperature was about 27 degrees celsius. This was a sit on top cruise. No other types of vessels were allowed. We were on the river for a little over 6 hours making this my longest trip. We saw a few Bald Eagles down by the Dauphin Narrows but they were not close enough for pictures.
