The selected droughts were incorporated in a computer model simulation

of the Poudre River water rights in order to estimate the impact on various

water supplies in the basin. The model, known as MODSIM, was previously

developed through research at Colorado State University. Some modifica-

tions and additional calibration were necessary for use in this particular

application. A separate version of the model was developed to simulate,

specifically, the operation of the City's water supply network. Operation

studies were conducted, using both present conditions and conditions under

various future scenarios, to estimate the safe average demands that could

be met by the City's water supply system during the selected droughts. The

model simulation work was performed by City personnel with assistance from

Resource Consultants, Inc.

The results of the model simulation runs were used to develop various

water supply strategies that could be adopted by the City for dealing with

droughts. These strategies include design criteria that could be used to

assure a r~latively drought-resistant water supply and emergency measures

that could be employed to help offset the effects of very extreme droughts.

Recommendations were prepared to assist the City in drought policy matters.
