Spring (natural water source)

Spring (natural water source) reference article on thruhikingwiki.com.

Overview

A spring is a natural point where groundwater emerges at the surface, providing a reliable source of clean water in many landscapes.

Key points

  • Often provides some of the clearest water along a route.
  • Flow rates vary seasonally based on groundwater levels.
  • May require short side trails for access.
  • Still requires treatment before drinking.
  • Often marked in guidebooks or trail apps.
  • More reliable than surface streams in dry environments.

Details

Springs form when groundwater under pressure reaches the surface through permeable layers or fault lines. These sources are prized by hikers for clarity, cool temperatures, and often consistent flow.

However, springs can fluctuate seasonally or dry up after prolonged drought. Even when water looks clean, treatment is recommended due to potential contamination from wildlife, surface seepage, or upstream human activity.

Springs may be piped, capped, or left entirely natural depending on land management practices.
