Ok season is just around the corner..... What is the primary water treatment along the C&O.. planning on doing a mid to late March trip.. realize pump handles aren't on until maybe the 15th of April or so. probably going to carry 4 liter's or so. most of my career was outside year round.. Hydration was top priority.. Multiple nights...not entire towpath.. Just starting my journey.. Everyone on here has been extremely helpful..
truly appreciated.. Nope Nowhere near lock 10 and the spill.. Probably
above Brunswick or Harpers Ferry.. was in Williamsport Saturday.. Tow path was nice...If One were to start in Williamsport ,, where would you park and how would you get to the towpath.. wooden bridge with steps not really an option with my load..Heading upstream towards Cumberland..Any creeks or tributaries you would filter or treat..springs??Thanks...
Did ya notice the 9th letter wasn't used in it's singular form..

I suggest you park in the parking area just north and east of Canal Lockhouse 44. You can see it in Google Maps’ satellite view. From that parking lot you can easily cross the Canal to the Towpath with your bike.

I’ve not needed or wanted to collect and filter native water between Williamsport and Cumberland albeit i usually make my trips when the pumps are working and do not consume large amounts of water when riding. (Probably just riding too slowly.) There is potable water available just off the trail in Hancock, Paw Paw, Oldtown and Cumberland that fulfills the need for water, if required. While there are a number of creeks that cross beneath the Towpath, I’ve not been watchful for such water sources and thus have no input to that question.

Thanks Rivnuts...How much water do you carry ..what would you say is a daily average on milage. This elder is planning 25 to 30 Tops with 40 pounds roughly .When utilizing the pumps from the Hiker/biker campsites how are you treating the water..Thanks again

Oh and the parking area you are speaking of ..Is that the one that leads to the boat ramp for the Potomac.
Sorry

Doug:

The parking lot I recommended for the easiest bike access to the Towpath in Williamsport is east of the power plant and dam which are downriver of Cushwa Basin. I will email you a couple of annotated maps that show where the parking lot I recommend is located and the path to the Towpath.

As for water between Williamsport and Cumberland note the following distances and off-trail sources to or at the destinations for potable water:

Williamsport to Hancock 25 Sheetz
Hancock to Little Orleans 16 Bills Bar Closed Monday to Wednesday
Little Orleans to Paw Paw 16 Liberty Gas and Convenience Store
Paw Paw to OldTown 10 Schoolhouse Kitchen-Closed Monday
Oldtown to Cumberland 23 Fairfield Inn Bikewash Station

Accordingly, and with proper planning, you can obtain potable water within your 25-mile daily max ride. Other forum participants can no doubt add other sources along the way.

How much water one carries or needs are personal and weather dependent. I usually only carry two water bottles for drinking and or cooking. I carry a foldable water bag to collect water from the pumps for washup and cleanup. I will occasionally use untreated pump water for cooking after boiling. If necessary, I will use the pump water and filter it for drinking water. I would typically add some flavoring to that filtered pump water since it has a taste that I don't particularly care for. I don't use iodine tablets and the like since I don't care for that flavor either and just rely on my Sawyer water filter for purity.
