I

The Town of Frederick (The Town) and Rocky Mountain Consultants, Inc. (RMC) prepared this report to
address the Colorado Water Conservation Board's (CWCB) requirements for receiving a CWCB raw water
system improvement project loan. The information in this report supplements the technical project Feasibility
Study completed by RMC in September of 2002. This previously completed report discussed the physical
attributes of the project site and described design alternatives for enlarging and rehabilitating the existing
facility. The following discussion focuses on additional information requested by the CWCR

2.0 PROJECT BACKGROUND

J

Milavec Lake is also commonly referred to as Firestone Reservoir and the actual dam embankment Structure
is referred to as Frederick Dam (DAMID 055319) by the State Engineer's Office (SEO). Frederick Dam fully
encircles the reservoir (ring dike) and provides mostly above grade storage. Frederick Dam is a Class 2, Small
size dam located in the Town of Frederick, Colorado ("The Town") in the southeast portion of Section 24,
Township 2 North, Range 68 West of the 6th Principal Meridian, Weld County, Colorado. The site is located
on the northwest corner of the intersection of Weld County Roads 13 and 18 and is approximately two miles

3.1 Current Statistics

I

Four thousand persons reside in the Town of Frederick based on the most recent population estimates.
Approximately 1,600 domestic water taps and 100 commercial/industrial taps are served by The Town's
potable water system. The Town also provides water to 89 water users in the Evanston development. The
most recent water year (November 1,2001 to October 31, 2002) report indicated that the Town's total potable
water usage was 1,001 acre-feet. Based on the records for this most recent water year approximately 69
percent of average annual household and town use occurs during summer months (May through September).
Further, an estimated 75 percent (or more than 520 acre-feet) of the total summer usage is for lawn/park
irrigation. Refer to Exhibit A.

0~~~~'

The Town is currently required to provide 1.2 units of Colorado Big Thompson (CBT) raw water to Central
Weld per single-family residence that is served. In turn, Central Weld treats and delivers 1.0 unit per single-
family unit to the Town for distribution.
