Well Water Conditions
Well water is generally available in across the park from mid-April (around the 15th) to mid-November (around the 15th).
Starting spring 2023, the well water in hiker-biker campsites are signed non-potable. Water from wells at paid campgrounds will remain potable and safe for drinking, cooking, or washing. Well handles are removed in mid-November each year to protect against freeze as per normal operating procedures.
The park works to ensure that there is a more reliable water source year-round for visitors in the park and that the drinking water that is provided is as safe as it can possibly be, especially considering that our wells are in a flood zone. The park will maintain potable water in a targeted number of wells in fee campgrounds. However, as a general precaution for wells located in a flood zone, you are advised to boil or treat the water before use for your own protection.
For hiker-biker campgrounds, the wells will be signed as non-potable and we ask that visitors bring their own water supply or water sanitizing equipment to treat well water before use. As long as visitors bring their own sanitization equipment, there will be a more reliable water source.
Drive-In Campgrounds: Well water within the drive-in campgrounds is potable and treated with iodine – do NOT drink if you have any iodine allergies or if you are on medication for an overactive thyroid. In general, well water is clean and able to be used without additional treatment. However, as a general precaution for wells located in a flood zone, you are advised to boil or treat the water before use for your own protection.
Hiker-Biker Campsites: Non-potable water is available in hiker-biker campsites. Please plan to filter, chemically treat, or boil the water before use for your own protection. The wells will remain in the hiker-biker campsites and, as long as visitors bring their own sanitization equipment, there will be a more reliable water source as handles will not be removed from these wells.
Visitor Centers, park buildings, and comfort stations are provided water by the nearby municipality and do not require drinking water sampling by the park. Please note that the Swains Lock campsite draws on the same municipal water as the Swains Lockhouse and will remain potable.
Water availability is subject to change. Always bring plenty of water with you as a backup option. Please plan your trip accordingly.
