what are the pros and cons of the hetch hetchy dam

Pros: Hetch Hetchy is an iconic, rare and spectacular landscape,
Hetch Hetchy is part of Yosemite National Park and its damming and flooding is by far the worst destruction of our national parks have ever experienced
Restoration would not only make Yosemite whole once again it would inspire people that we don’t need to live with mistakes of the past

Cons: Prinstine – Hetch Hetchy Reservoir collects and stores pristine snowmelt and precipitation from the protected Yosemite National Park wilderness area.
No Filtration – Water collected and stored in Hetch Hetchy Reservoir’s granite basin consistently meets and exceeds Federal and State Filtration standards for safe drinking water. No filtration of this source water is necessary or required.
Reliable Water Delivery – The water storage provided by Hetch Hetchy Reservoir is invaluable in its ability to capture snowmelt and store the water for reliable delivery throughout the year and across multiple years. This storage is heavily depended upon during droughts when the natural hydrology is in capable of meeting water needs even when rationing is in place.
Gravity-Driven – The high elevation of Hetch Hetchy Reservoir and the engineering infrastructure of the Regional Water System move water from its source, across the state, and to its customers using little more than gravity.
Renewable, Dependable Electricity – Hetch Hetchy Reservoir, along with the waters retained in Cherry Lake and Lake Eleanor, provide the gravity-drivein water that is transformed into renewable, dependable electricity.”
