The Meso County Irrigation Dlstna:t, "Stub ditch ':

found In 1918 that Its pumpIng plont wos worn out
A contract for carriage of Stub water In the project main
canol, WIth 0 limitation Similar to thO! In the Pnte Con-
tract os to power water was then made wlfh the Bureau
of Reclamation. Much Stub land IS higher than the pro-
ject mOln canol, Including lands on the lower Side of that
calla I The water of the Price ditch IS therefore dropped
17 feet 1010 that dlfch through 0 turbine direct. connected
to 0 pump whlch supplies the Stub ditch, at about 0 30
foot 11ft Much water from the Stub ditch is corned
- across the project main candl to ItS lower Side In pipes
that serve lands too high for laterols from the project mom
canol and some Stub lands ore served directly from the
project conal.
The Orchard Meso Irrigation District was promoted,'.
os of October 25, 1907, by resldenlts of that area who
preferred 0 system separate from th,e Gro nd Va II e y
ProJect of the Bureau of Reclamation. The works
consisted of 0 sfeel Wicket dam one -half mile above
the Grand Valley DIversion Dam ~ about 9 miles of canol
In the conan of Colorado river, of which 6 mlles was In
untreated timber flume; 0 pumping plant contolnlOg two
turbines direct connected to pumps, one mile south of
PalIsade; two distribution canals, each about 15 miles
long, fa corry respectively 80 second~feet at 0 40 foot
Ilft and 60 second -feet at 0 130 foot lift. Water was
first delivered In 1910.

DUring the non. IrrigatIOn season the demand IS limited to
800 second- feet of power wafer IJnde~ stream pncnty 16,
and such amounts of domestic water os may, several times
each winter, for periOds of several days, be dIVerted and run
by each of the ditch systems. While the aggregate amount of
such domestic decrees IS approxlmotely 700 second -feet,
the actual use IS negligoble and the decrees were set at
thiS hlQh figure to preclude the posslbil IlJly of trouble from Ice,

HISTORICAL

The Grand Volley conal of The Grand Valley Irrigation
Company has the second prlonty from Colorado nver proper,
10 CololOdo. Only 0 Stewart ditch near Dotsero IS
senior " right for 2 40 second - feet "was not, however,
the first ditch started nor completed In tne Grand Volley
On MOlCh I, 1882, work started on the Pioneer or Mesa Co
ditch (,1111 In use os port of the Grond Valley System) and
water flam It was used April 20, 1882. The PaCifiC Slope
drtch, 'ng since obondoned, started work on March 20,
and ,we1t Into use July 1,1882. The Grand Valley Ditch
Compacl ,lineal predecessor of The Grond Volley Irrlgollon
Compooy,orQanlzed early the some summer, hod ItS ditch
located and some work done hefore the end of the year.
In January 1883, Matt Arch, who hod pioneered many
ditches ,n Western COlorodo, and for whom 0 ditch he
bUilt on Tomlchl Creek IS named and still In use, took
charge of the reorganized Grand River Ditch company
and on May 16 water from thiS conal was delivered for
use. In i883 the Independent Ronchmen's ditch was
slarted and some "oter supplied fhot fall. However the
heodwOlks of thiS ditch were lost In the great flood of
1884 and It thereafter to'lk water from the Grand Volley
system In 1886, 011 the ditches In the volley that ore
named above were consolidated With the Grond River conal,
then'-'owned by the Travelers Insurance company, and
_ . ~~~~~_loter the property was sold to Its woter users
who e\ganlzed The Grand Volley Irrigation compan} to
toke ,the property over While the Grand Valley canol
decree IS doted August 22, 1882, It might rightfully have
claimed 0 priority for 0 port of ItS water, on account 01

In 1917 the wooden flume hod almost completely de-
cayed, the pumping plant was In very poor repair and the
DIStllCt proposed 0 rehabliltotlOn of ItS works by the
Bureau of Reclamation The Bureau offered, at 0 cost
of hoo ,000 to rebuild the works to supply 800
second .feet from the project main canol , by means
of a Siphon under Colorado river, from the upper end
of tunnel No 3. DUring the Irrigation season tne Orchard
Mesa Irngotlon District was to receive 400 second- feet
of thiS water for pumping and Irngatlon and 400 second
feet was to be used In the power plant of the Grand
Volley Project, and the whole 800 second-feet was
to be used 10 the power plant dUring the nonlrrlgatlOn
season. The Orchard Meso dam and about 5 5 miles
of Its conal was .~bandoned.
from the river Siphon 0 conal In concrete bench
flume extended for I 57 miles to the Vlneland6 and
!he old conal was used for about I 80 miles to the
pumping plant. Four vertical direct connected turbines
and pumps were Installed and the distribution canals
praclicolly rebuilt.
The Grand Va Iley Project of the Bureau of Recla-
motion, on which work beQon 10 1908 , IrrIQotes 0 long
striP of lond north of other systems from 0 pOint north
of Clilton to 0 point 5 miles northwest of Mock. Its
works Include 0 low overtlow dam on grovel ,surmounted
by a 0 foot steel roller crest; 0 mom canol deSigned
