San Joaquin Valley Farmers: The Hetch Hetchy Debate
We do not want the dam to be built--it will interfere with the irrigation of our crops.
The Tuolumne River is our major source of water
Agriculture is the main industry in the San Joaquin Valley and feeds surrounding communities
Dams can negatively impact the environment and can be costly to build
How it Would Affect the Environment
The dam disrupts the nutrient flow into the soil, which causes soil erosion
When dams are built, breeding grounds and habitats for fish are damaged, which can lead to species becoming endangered/extinct
Many dams do not include bypass systems for fish, which prevents migration
A scientist from NASA, Dr. Benjamin Fong Chao, found that human interference with the natural flow of water increases the speed of Earth's spin
Approximately one reservoir decreases the length of a day by 0.2 millionths of a second
The chemistry of the water can be altered-->higher concentration of salt and lower D.O. levels\
Impoundments increase the probability of evaporation, which leaves even less water available
Economic Implications
Less water=less crops=less food for surrounding areas
For San Joaquin Valley, many people would lose their jobs because of agriculture's economic importance
With less crops to sell, there will be a smaller economic flow, which will decrease quality of life
The cost of building the dam takes even more money out of the economy
The dam would cost billions of dollars
How the Dam Would Affect Us
We use 3,600 acre-feet of water per day for crops and this would have to be cut to accommodate the needs of San Francisco
The flow of the Tuolumne River is 4,700 acre-feet per day
Without the dam, there is only 1,100 acre-feet of water remaining daily
With that little left, the affects of the dam along with San Francisco's water use will leave little water left
The dam would prevent the flow of nutrients to soil for crops
