<br />INTRODUCTION
<br />
<br />Following World War II, areas such as Los Angeles, the San Francisco Bay
<br />area, and the Pacific Northwest began feeling growth pains. In more recent
<br />years the Eastern Front-Range of the Colorado Rocky Mountains has incurred
<br />similar growth characteristics, For example, during the period 1970 through
<br />1977, cities such as New York, Philadelphia, and Boston saw their populations
<br />decrease at rates of 8% to 10%; Denver, Colorado, during the same period.
<br />incurred a population increase of over 20%. This was further reflected in
<br />Northeastern Colorado where, during the same period, population increased
<br />from approximately 260,000 to over 380,000. or 46%,
<br />The impacts of this rapid urbanization on the water resources available to
<br />the Northeastern Colorado area and on its water distribution systems are
<br />numerous. The options available to resolve the problems associated therewith
<br />are somewhat limited. To better understand these impacts, however, one must
<br />fust have a basic understanding of the area and its base water supplies.
<br />Northeastern Colorado has been agriculturally oriented in terms of its basic
<br />economy since about 1850, when the development of over 850,000 acres (344,250
<br />ha) of prime farm land began, In an area that receives less than 14 in, (355
<br />mm) of rainfall annually, this industry, obviously, must depend on irrigation
<br />practices to survive, Thus, the period between the mid-1880s and early 1900s
<br />saw a great flurry of reservoir and canal construction along the tributaries of
