Alternative No. 1 — New Cache la Poudre Irrigating Company and Cache la Poudre
Reservoir Company
Background: New Cache la Poudre Irrigating Company
The Greeley No. 2 Canal (a.k.a. New Cache Ditch) diverts water from the north side of
the Cache la Poudre River and services lands that extend from the Windsor/Timnath
area on the west to the Barnesville area on the east.
The New Cache system includes the main Greeley No. 2 Canal as well as numerous
laterals. New Cache delivers a variety of sources to its shareholders for irrigation. In
addition to water diverted directly from the river, New Cache also deliveries irrigation
water to their shareholders from Timnath Reservoir (a.k.a. Cache Ia Poudre Reservoir),
Big Windsor Reservoir, Fossil Creek Reservoir, CBT, and other minor sources. Timnath
and Big Windsor water are delivered directly to the Greeley No. 2 Canal downstream of
the Greeley No. 2 Canal river diversion, but above Kern Reservoir. Fossil Creek and
CBT are typically diverted at the river for delivery to New Cache shareholders. New
Cache also uses the Kern Reservoir as an equalizer reservoir.
New Cache has direct flow rights for diversions from the Poudre River through the
Greeley No. 2 Canal. There are 2,499.69 shares of stock in the company.4 The
following table includes some pertinent water rights information associated with this
water right.

Background: Cache la Poudre Reservoir Company
The Cache Ia Poudre Reservoir (CLP Reservoir) Company owns the rights decreed to
Timnath Reservoir, which is an off-channel reservoir located five miles northwest of

an inlet canal as well as other inflows from tributary streams and drainage inflows. The
reservoir outlet delivers water directly to the Greeley No. 2 Canal and the Lake Canal.
The CLP Reservoir Company is often associated with the New Cache system because
many of the shareholders in the New Cache system also own shares of stock in the
