It is recommended that hikers filter, boil or chemically treat all water before consumption or use. Water purity in the backcountry cannot be guaranteed. The GATC does recommend that hikers replenish personal water supplies while on trail whenever water is available.
Please note that in colder months, some springs may freeze.
In the linked table, we use the following definitions:
- Good - Water level is in the range of normal, full flow and water collection is easily accomplished
- Low - Collection remains easy, though may take more time or use of alternate pool or cascade.
- Marginal - Water level is noticeably low. Collection is significantly impacted requiring more time and perhaps 'scooping' of water out of low pools.
- Dry - Effective collection not possible. Water is very shallow or not existant. Source should be considered dry and unusable.
