Sarah, my dad, and I took a canoe and kayak trip down the Big Spring Creek in Newville, Pennsylvania. The creek is beautiful, with clear water, many aquatic plants, and much waterfowl.
Since the creek has a tiny drainage and is primarily spring fed, it does not flood regularly (if at all) and is hence heavily silted. For about the first 3rd of our trip, the canoe was constantly scraping the bottom and getting stuck. My dad in the sea-kayak had a little bit shallower draw and only got stuck once.
After the first 3rd of the trip the channel deeped, but was still quite narrow, requiring a lot of maneuvering of the large canoe.
In a few spots fallen trees block the channel, though we were able to gingerly maneuver over or under them.
Be aware that a State Boat Registration sticker is required on all boats.
