Clarity doesn’t protect itself. From urban stormwater retrofit projects to naturalized floodplains, we’re working upstream to ensure clean water downstream.
We restore Lake Tahoe’s watersheds to what they were meant to be: natural filters for Lake Tahoe. Watershed restoration stops pollution before it hits the lake, protecting water clarity for generations to come.

The Aquatic Invasive Species Program protects Lake Tahoe from non-native species that threaten water quality, native habitats, and recreation. Through watercraft inspections and targeted control efforts, the program prevents new introductions and reduces existing populations. These actions help preserve the ecological integrity of Tahoe’s waters.

The Watershed Restoration Program restores natural streams, meadows, and wetlands that play a critical role in protecting Lake Tahoe and it’s ecosystem. By improving habitats, reconnecting floodplains, and restoring natural processes, the program strengthens our watersheds while advancing regional environmental threshold goals.

The Stormwater Management Program reduces sediment, nutrient, and stormwater runoff as well as pollutants that threaten Lake Tahoe’s water quality and clarity. By implementing best management practices (BMPs) and stormwater infrastructure improvements, the program helps slow, filter, and infiltrate runoff before it reaches the lake. These efforts support long-term clarity goals while working collaboratively with property owners and local jurisdictions across the Basin.
EIP watershed restoration and water quality projects help control stormwater, stabilize slopes, and restore floodplains, allowing runoff to slow and filter naturally. These projects do more than protect the lake’s iconic blue. They restore wildlife habitat, reduce the risk of flooding, and build climate resilience.
Lake Tahoe remains one of the clearest lakes on Earth — not by accident, but because of decades of coordinated action. Explore some of our landmark projects in your own backyard.
