North Platte River Basin

Wet and Dry Periods

Every year, there is at least one lOa-year flood
somewhere in the state. Colorado's total flood
losses to date have been documented to be
$4.9 billion. The North Platte Basin's most
recent flood event was in 1984. The estimated
total historic damages for this basin are
$ 110,000 to date.

The North Platte Basin is
comprised of essentially one
county. The small portion in
Larimer County has very
little development. Changes
in population from 2000 to
2030, including percent annual growth rate on a county level, are shown in the table above. During that time, the
population in the basin is expected to grow to 2,000 people, an increase of 25 percent.

The North Platte Basin is
projected to increase in
municipal and industrial
(M&I) and self-supplied
industrial (SSI) water
demand by 100 acre-feet
(AF) by 2030. M&I is defined
as all of the water use of a typical municipal system,
including residential, commercial, industrial, irrigation,
and firefighting. Large industrial water users that have
their own water supplies or lease raw water from
others are described as SSI water users. M&I and SSI
water demand forecasts for the North Platte Basin are
shown in the table above.

The 2000 and 2030 gross demands are presented
in the table along with the projected conservation
savings. Conservation practices include
ordinances and standards that improve the overall
efficiency of water use, such as installation of low
water-use plumbing fixtures. As the table
indicates, the North Platte Basin will need an
additional 100 AF to meet the increased demands
of M&I water use. The majority of the demand is
expected to be met through existing supplies and
water rights and through the implementation of
various projects and processes.
