OverviewOverview“Water is bound to man, indeed to life, by a long-lasting familiarity,
by a relationship of multifarious necessity, due to which its uniqueness is hidden beneath the crust of the habit.” -Primo
Levi• History• The Problem
– Water Use– Water Sources– Ecological Problems
• Governance Strategies– Case Study: Owens Valley– Market Based– Community Based
• Sustainable Use?

• Homestead Act of 1862 – Encourage
people to move west
– “Facilitate yeoman ideal and speculation”
• General Water Rights– Use water on
your land so long as you don’t interfere with use downstream
•Desert Land Act of 1877–“First in time, first in right”–Prior appropriation–Water monopolies

• Newlands(Reclamation) Act of 1902– Established the
Bureau of Reclamation
– Provided for project planning, contracting and construction of dams and aqueducts
- Established districts with federal control - Increased water availability allowed for city population growth
Lower Colorado Region

• Owens Valley 1905-1913– Water needed for the growing cities– Solution: 250 mile Aqueduct to Los Angeles
![Page 7: Water Use in the Desert Southwest - Cornell University · “Water is bound to man, indeed to life, by a long-lasting familiarity, by a relationship of multifarious necessity, due](https://reader034.fdocuments.us/reader034/viewer/2022042312/5edb19ebaa8629317168ae51/html5/thumbnails/7.jpg)
• Hoover Dam 1930– More water for
growing cities• Colorado River Compact
1922– Allocate river water– Meet stakeholder
needs• Boulder Canyon Act
1928– Hoover Dam – Colorado River
Aqueduct provides water to Los Angeles
Early legislation encouraged growth and more water use, rather than tackling the problem of water shortage

95% of Owens Valley by 1930• By 1924, Owens Lake
almost completely dry• Dust storms

MarketMarket--based approachesbased approaches• Aspects of market approaches
– Groundwater and aquifers have inherent common-property characteristics and social values difficult to account for in markets
– Markets require clear, enforceable property rights, minimal externalities, feasible competition
![Page 24: Water Use in the Desert Southwest - Cornell University · “Water is bound to man, indeed to life, by a long-lasting familiarity, by a relationship of multifarious necessity, due](https://reader034.fdocuments.us/reader034/viewer/2022042312/5edb19ebaa8629317168ae51/html5/thumbnails/24.jpg)
MarketMarket--based initiativesbased initiatives• Tax incentives and
rebates– Denver water
• Agricultural water allocations– Water rights
• Technological advancements– Efficient Water Use
• Aquifers, Irrigation

CommunityCommunity--Based ApproachesBased Approaches
• Community approaches may be preferable– Nature of water conservation demands
involved and moralistic approach
• Require an educated public– Urbanites must become aware of water
problem– All communities must be working together

Examples of CommunityExamples of Community--Based Based ApproachesApproaches
• Market-Community Partnerships– Denver Water Company
• Advertisement Campaigns– Led by water companies
like Suburban Water Systems
– Suggested changes both inside and outside the home

• Education of Youth– Institute for Water Ed.– S. Nevada: “H2O The
Source” teaching materials– Water Conservation in
Curricula– New generation must be
water-conscious
• Change of culture– Old Status Quo must go– Entire communities must
change their perception– New Image of the Southwest

Conclusion Conclusion –– Sustainability?Sustainability?
• Urban water use in American Southwest cannot be sustainable
• Still, steps can be taken to reduce water footprint of cities– Command and Control Approach– Market-based Approach– Community-Based Approach
• Though true sustainability cannot be reached, there are indeed positive signs
