Julesburg Irrigation District
Approval of an Emergency Loan in amount of $590,000 to replace the
District's Diversion and Headgate Structure on the South Platte River.

BACKGROUND

The Julesburg Irrigation District (located in Logan County), has submitted an application for an
emergency loan to replace the river diversionlheadgate for the Harmony Ditch No, 1. They
have requested a loan in the amount of $590K (75% of the estimated total project cost of
$785,630),

The project is located on the South Platte River, about 4 miles southwest of the Town of Crook,
This diversion is used to fill the Julesburg Reservoir, and to provide water via the Highline
Canal, the Settlers Ditch, and the Peterson Ditch for irrigation, The existing diversionlheadgate
was originally built around the turn of the century, and the west diversion was rebuilt in the
1960's,

The west diversion structure was washed out and destroyed during high water during the period
June 18 to June 24, 1997, The concrete floor was undermined by flood waters, and 1 pier and
about 75 feet of the floor collapsed into the hole, The right abutment pier and concrete was
displaced 4 feet downriver, and is assumed to be damaged beyond repair. The diversion can not
be used without installation of a temporary sand dam,

It costs about $1500 to install a sand dam (114 mile in length), and 2 have already been washed
out this year. A sand dam will not work for spring diversions, which is the time the District
can legally divert from the river to fill the Julesburg Reservoir.

Preliminary engineering design work as well as a feasibility cost estimate have been provided
by W,W, Wheeler and Associates, A preliminary design and cost estimate has also been
prepared by Zoyiopoulos and Associates Engineering, of Greeley,
