Gualala River Watershed

The 300 square mile Gualala River watershed terrain is mountainous and rugged, with the river and numerous tributaries flowing in gorge-like valleys with narrow bottom lands.

  • The watershed includes 75 miles of salmon and 178 miles of steelhead habitat.
  • The Gualala River is included on the Clean Water Act 303(d) list for impairments associated with excessive sediment and high temperatures resulting from past land use.
  • Climate near the coast is generally mild throughout the year. Rainfall averages 38 inches at the coast and up to 70 inches per year inland.
  • One of the NGOs conducting on-going data collection for science-based stream restoration in the Gualala River watershed is the Gualala River Watershed Council.
