Sitting at the top a major watershed that feeds directly into Lake Tahoe, Diamond Peak takes great responsibility in mitigating erosion, wildlife, and water quality impacts. In addition to responsible use of Lake Tahoe’s water supply and frequent water quality testing at beaches and nearby streams, Diamond Peak and IVGID help Keep Tahoe Blue by pumping all of their treated sewage water outside of the Lake Tahoe basin to the Carson Valley, where it is released into a wetlands area owned by IVGID that creates a waterfowl habitat. Leftover solids are removed and transported to Bentley Ranch in Minden, NV for composting. After their lodge renovations in 2010, the ski resort completed a $1MM riprap installation in a Stream Environmental Zone to manage all runoff through a culvert system underneath the new parking lots to meet Tahoe Regional Planning Agency (TRPA) best practices. Lastly, all cleaning products are natural and biodegradable and no pesticides are used during summer slope maintenance operations, which would leach into the soil and make their way to the lake.
