Big Barnes Ditch and discharges into Lake Loveland at a decreed rate of 1000 cfs. It is then .. -
passed through Lake Loveland and discharged out via the North Outlet canal which flows into
Dry Creek, and ultimately into Horseshoe Reservoir. The section of canal and natural drainage
channel is approximately 7,500-feet in length. In 1999, SLRC moved the north Lake Loveland
outlet flow control function from the five-tunnel Dry Creek Railroad culvert structure (about 1250
north of Lake Loveland) to a new location within 250 feet of the north end of Lake Loveland.
The new Lake Loveland north outlet control consisted of a thirty-foot wide pneumatically
operated hinged crest gate, designed to flow at 1,000 cfs.

Now that SLRC has relocated the north Lake Loveland outlet control function away from the
existing Dry Creek Railroad culvert structure, their next objective is to remove and replace the
existing deteriorated structure with a new railroad bridge in order to pass 1000 cfs. The
construction of the new railroad bridge would accomplish SLRC's objective of being able to
safely move 1,000 cfs from the Big Thompson River through Lake Loveland to Horseshoe
Reservoir, and ultimately to Boyd Lake, thus removing a serious bottleneck in the flow path of
water. Presently the railroad culvert structure restricts the flow capacity, and limits the SLRC
and GLlC's ability to start the runoff season with Lake Loveland in a full condition. The railroad
crossing was constructed in 1905 under agreement with the Colorado & Southern Railway
Company (now Burlington Northern & Santa Fe - BNSF). The agreement allowed SLRC to
construct a canal structure under the railroad, with the understanding that SLRC would "at all
times bear all expense incurred in the construction, maintenance, repairs or renewals of said
ditch and tunnel." The proposed project would include removal and replacement of five existing
railroad-crossing tunnels with a pre-fabricated concrete bridge. Overall storm drainage
considerations are being coordinated with the City of Loveland. The Lake Loveland North
Outlet control gate discussed above is automated and equipped with an alarm system to insure .
that routine irrigation operations do not exacerbate downstream flooding during a storm event.

Feasibility Studies

SLRC, through their engineer John Gauthiere, P.E., has completed the feasibility study in
accordance with CWCB guidelines. The study includes an assessment of alternatives to
replace the Dry Creek Railroad Crossing.

Seven Lakes Reservoir Company

SLRC is a Colorado mutual ditch company and a non-profit corporation registered in the State
of Colorado, in good standing. The Company was incorporated in 1900 and there are currently
63 shareholders and 400 shares of stock. The Company is governed by a 5-member Board of
Directors. Per their Bylaws, SLRC has the authorization to set annual assessments, the
authority to shut off water delivery to shareholders that fail to pay assessments, and the
authority to rescind shareholder stock. The Board of Directors has the power and authority to
borrow money on the company's behalf and enter into contracts. For the year 2005 the SLRC
had income of approximately $80,000 with expenses of approximately $75,000. Assessments
for the past several years have been $175 per share.

Water Riahts

SLRC has no direct flow rights. They have a storage decree for Horseshoe Reservoir for 8,432
AF, with a appropriation date of April 28, 1902 and adjudication dates of March 22, 1890 and
June 29, 1919. Full storage at G. H. 26.5 is 7,796 AF. Storage in the other small reservoirs
totals 607 AF, for a total of 8,403 AF in the SLRC system. SLRC also owns 26.5 shares of
Louden Irrigation Canal and Reservoir Company that is discharged directly into Horseshoe

.
