• Board Meetings - Doc Type: Memo

The Joseph W. Bowles Reservoir Company (Company) owns and operates Bowles No. 1
Reservoir, located in the southwest metropolitan area of Denver. The Company was formed in
1906 and currently has 50 shareholders who use the water for golf courses, parks, open space, and
some individual ranches for irrigation water. The Company is applying for a loan to implement
several repairs to correct dam - safety deficiencies and improve the long - term performance of
Bowles No. 1 Dam and to rehabilitate the deteriorating reservoir inl et ditch. The dam
rehabilitation includes widening the crest, reconstructing the upstream slope, and installing a
seepage collection and toe drain system on the downstream slope. Work on the inlet ditch includes
removing trees, reconstructing the ditch c ross section and alignment, placing slope protection in
high erosion areas, and installing a flow control pipe that will provide for discharge of excessive
ditch flows into an existing spillway and drainage structure. The Company plans on submitting the
fi nal design to the SEO by February 2010 and beginning construction in August 2010 with
completion by February 2011.
16. North Sterling Irrigation District – North Sterling Reservoir Rehabilitation
Authorization: Construction Fund County: Logan
Water So urce: South Platte River Project Yield: 74,590 acre - feet
Terms of Loan: $1,094,840@2.25% for 2 0 yrs. Projec t Type: Reservoir Rehabilitation
The District owns and operates the North Sterling Reservoir (Reservoir) located in Logan County
and provides sto red and direct flow water to landowners within the District’s 40,917 acre service
area. The District service area begins just east of the North Sterling Reservoir approximately 15
miles northwest of Sterling, Colorado and extends east to just northeast of Crook, Colorado. The
Reservoir faces the possibility of a storage restriction from the State Engineer’s Office without the
construction improvements to the current spillway and the dam. In order to retain full storage
capacity, the District intends to e nlarge the existing spillway, raise the dam crest, and install a
seepage collection system at the Reservoir. Construction is expected to take place in the
summer/fall of 2009 with a 90 day construction window.
17. Snowmass Water and Sanitation District – Zeigler Reservoir Water Management System
Authorization: Construction Fund County: Pitkin
Water Source: Snowmass Creek Project Yield: 1,800 acre - feet
Terms of Loan: $1,952,805@4.25% for 2 0 yrs. Projec t Type: System Improvements
The District’s pro ject involves the construct ing of a new delivery system ; which includes the
construction of a pump house, approximately 1,400 ft of pipe, construction of a flow control
building, installation of telemetry and electric power. The District diverts water for treatment
from East Snowmass Creek and East Snowmass Creek Spring, Brush Creek and Snowmass
Creek. The District presently does not have a useable raw water storage facility, but purchased
Ziegler Reservoir (aka Lake Deborah) in 2008 for the express purpose of improving system
reliability by expanding the reservoir from its current 57 AF to approximately 225 AF. The
District currently serves approximately 3,500 full time residents and during the winter ski season
an additional 10,000 to 12,000 residents. To regulate flows and provide a supply during times of
diminished stream flows, a system to divert water to and pump water from the reservoir is
required. This Project will help the District to deliver water to utilize Ziegler reservoir as well as
serve for t he planned expansion of the reservoir. Final Design is near complete and construction
is scheduled to begin in this summer and completed by the end of 2010.
18. Riverside Reservoir and Land Company – Riverside Reservoir Spillway Enlargement
