SUBJECT: Agenda Item 8d., January 29-30, 1997, Board Meeting--
The San Luis Valley Canal Company
Approval of a Construction Fund Loan in amount of $188,000 to reconstruct
a concrete check structure on the canal.

BACKGROUND

The San Luis Valley Canal Company (SLVCC), located in Rio Grande and Alamosa Counties,
has submitted an application for a loan to reconstruct a concrete check structure on the canal.
They request a loan of $188,000 (75 % of the maximum estimated total project cost of
$250,000).

The San Luis Valley Canal diverts water from the Rio Grande River approximately 3 miles east
of Monte Vista. There is a diversion structure on the river, and 2 concrete check structures on
the canal within 1.5 miles downstream of the diversion. During flooding, water often enters the
canal downstream of the river diversion. The purpose of the check structures is to prevent these
flood waters from flowing down the canal, destroying the canal, the headgates, and the
downstream regulating structures. (See attached map.)

These check structures are about 60 years old, and in poor condition. The company has adopted
a schedule for the replacement of canal structures, starting with the upstream check structure.

Preliminary engineering design work as well as a draft feasibility study have been completed by
Laurie Howell and Jeff Koster of the NRCS Alamosa Office. (The Preliminary Engineering
report is attached.)

The SL VCC held their annual meeting January 13, 1997, and voted to proceed with the project.
Construction is scheduled for fall 1997.
