The Izaak Walton League is one of America’s oldest and most successful conservation organizations – and we are the only organization training, equipping, and coordinating volunteer water quality monitors on a national scale. These volunteers are the heart and soul of our common-sense conservation mission. Through member-driven bottom-up governance, the Izaak Walton League is protecting outdoor America in communities across the country, while working strategically at the national level to win critical conservation battles.
