Pennsylvania is experiencing drought conditions that are affecting water availability along the trail. Several reliable springs listed in older guidebooks are currently dry or reduced to a trickle. Notable dry sources include the spring near Allentown Shelter, the reliable piped spring at Kirkridge Shelter, and multiple sources in the Lehigh Gap area. Hikers should carry extra water capacity and plan longer water carries between confirmed sources. Towns remain the most reliable resupply points for water. Check recent trail reports on FarOut or Guthook before each section, and ask other hikers about current water conditions. Expect to carry 3-4 liters between sources in areas that would normally require only 2 liters.
