The Hetch Hetchy Debate:
San Joaquin Valley Farmers Defense: San Joaquin Valley Farmers Tuolumne River: our major water source.
If the river is dammed, large amounts of water used for farming will be diverted to San Francisco City.
Used for irrigation of crops
Crops we grow feed people all over California and beyond. We need enough water to irrigate 257,00 acres of farmland.
Daily water consumption for crops: 3,600 acre-feet 1 acre-foot= amount of water needed to cover 1 acre of land with 1 ft of water. How We Run Our Lives Normal flow of Tuolumne River is 4,700 acre-feet/day. During periods of flooding: 40,000-60,000 acre-feet/day That leaves only 1,100 acre-feet to give to the City of San Francisco, a day.
They'll need a lot
more. It Effects You (and your food) If water is used to supply the City of San Francisco, it could prompt a wide-spread food shortage.
San Francisco is growing rapidly
Because of the increasing water demands that need to be met in a continually growing city, all water will eventually divert to San Francisco's water supply.
Farmers will be left with insufficient irrigation capacities.
Without proper irrigation farmers will not be able to produce as many crops.
Less crops= Not enough food to supply families in California and beyond.
Not enough food= Food shortage and famine. "It was like lying in a great solemn cathedral, far vaster and more beautiful than any built by the hand of man."

"In the Grand Canyon, Arizona has a natural wonder which is in kind absolutely unparalleled throughout the rest of the world. I want to ask you to keep this great wonder of nature as it now is. I hope you will not have a building of any kind, not a summer cottage, a hotel or anything else, to mar the wonderful grandeur, the sublimity, the great loneliness and beauty of the canyon. Leave it as it is. You cannot improve on it. The ages have been at work on it, and man can only mar it." -Quote from Theodore Roosevelt Bibliography http://www.nps.gov/thro/historyculture/theodore-roosevelt-and-conservation.htm http://www.sierranevadaphotos.com/gallery/hetch_hetchy/index.asp http://www.nytimes.com/2012/09/10/science/earth/hetch-hetchy-valley-measure-pits-bay-area-against-environmentalists.html?_r=0 Hetch Hetchy Valley After Before Located in Yosemite National Park, John Muir once said it was "one of nature's rarest and most precious mountain temples." 1890 - Yosemite National Park established
1890 - San Francisco Mayor James Phelan first proposed damming Hetch Hetchy to create a reservoir for San Francisco.
1903 - Mayor Phelan applied to the Interior Department for rights to Hetch Hetchy's water -- denied
1905 - Mayor Phelan applied for water rights to Hetch Hetchy -- denied
1906 - The San Francisco Earthquake and Fire Time frame At the valley floor was the Tuolumne River. http://www1.assumption.edu/users/mcclymer/His130/P-H/hetch%20hetchy/default.html Since 1987, seven major institutions have researched various aspects of restoring Hetch Hetchy Valley and all concluded that restoration is both feasible and practical:
1.U.S Bureau of Reclamation Report (1988)
2.National Park Service Report (1988)
3.Environmental Defense Report (2004)
4.University of Wisconsin Report (2004)
5.Restore Hetch Hetchy Report (2005)
6.Journal of the American Water Resources Association, UC Davis (2006)
7.California Department of Water Resources Report (2006)
8.The Water Sustainability and Environmental Restoration Planning Act of 2012 http://www.hetchhetchy.org/ Negative Effects of Dams animal migration is interrupted Dams disrupt the relationship between land and water, destroying the existing ecosystem. Soil erosion; dams hold back sediments normally found in river flow. The vast majority of large dams do not include proper bypass systems for these animals, interfering with their lifecycles and sometimes even forcing species to extinction. Dam reservoirs in tropical areas, due to their slow-movement, are literally breeding grounds for mosquitoes, snails, and flies, the vectors that carry malaria, schistosomiasis, and river blindness. NASA geophysicist Dr. Benjamin Fong Chao found evidence that large dams cause changes to the Earth's rotation, because of the shift of water weight from oceans to reservoirs. Because of the number of dams which have been built, the Earth's daily rotation has apparently sped up by eight-millionths of a second since the 1950s. Chao said it is the first time human activity has been shown to have a measurable effect on the Earth's motion. http://www.arch.mcgill.ca/prof/sijpkes/arch374/winter2001/dbiggs/enviro.html Conclusion to Our Argument Water is a very precious substance on this plant, supplying us with the fruits of its natural affinity. Wheat, corn, and other crops supply this state and country with the nutrients we need to live. The construction of the Hetch Hetchy dam will drastically decrease our food security while increasing our financial burden. We hope you consider this argument valid and help vote against the construction of this dam. What It Should Be 1908 - Interior Department approved the City's request -- 86% of San Francisco voters approve the project and $600,000 to purchase the "lands, rights, and claims" of Hetchy Hetchy
1909 - Taft administration Secretary of the Interior Richard Ballinger suspended the Interior Department's approval
1913 - Woodrow Wilson appointed former San Francisco City Attorney Franklin Lane as Secretary of the Interior - - Congress passed the Raker Bill
1923 - Dam completed ~A Message from Your Farmers Less Food Means Less Money In the long run, draining the water from the Tuolumne River will mean less money in your pocket and more spent on food just to live:
With less water for irrigating our crops, our food production will decrease and cause a food shortage.
This causes a high raise in food prices throughout the area.
We will have to rely heavily on importation to supply markets with adequate amounts of food.
Markets will have to spend more money buying imported goods.
That means that they will still raise prices in order to make a profit.
Basically, less food = higher prices. Importing food = higher prices
Higher prices = less money for you Over-populated As cities are becoming more populated, less and less water is available for agricultural use but farmers need more water before to meet the demands of all these people. So they must drill even further into the aquifers, which cause them to become nonrenewable. But this also has a negative effect on the environment since it can cause potholes and destroy our cropland.
