BEAR CREEK RESERVOIR OPERATIONAL STUDY

1.0 INTRODUCTION

1.1 Purpose

The purpose of this study is to develop a computer model of

the Bear Creek Reservoir to test operational theories of using

the Reservoir for supplemental municipal water supplies. Hydro-

logic data for the years 1949 to 1957, estimated water rights

yields and projected storage release requirements of eight

governmental agencies were utilized to test the operational

theories. Four different scenarios, each with an additional

"bookover" modification were tested. The objective of the study

is to minimize the fluctuation of the reservoir water levels

between the two assumed elevation limits given in each scenario

while creating the maximum storage production for each agency

from an assumed storage space allotment. The study will provide

information that may be used by the participan~s in reaching

agreement on how and who compensates the stream for the evapora-

tion from the on-stream reservoir.

1.2 scope of study

1.2.1 Background

The Reservoir is a U.s. Corps of Engineers' flood control

facility located on Bear Creek near Lakewood and Morrison, Colo-

rado. In May 1979 the Indian Hills Water District (Indian

Hills), the Genesee Water and Sanitation District (Genesee), the

Evergreen Metropolitan District (Evergreen), and the Town of

Morrison (Morrison) requested storage space in the permanent pool"
