March 1996 Final

Colorado priority system. In this way, the yield of the water rights will be determined by the
water supply conditions in the Arkansas River system and by the exercise of the senior water
rights, as has been the case historically. As shown in both Plate 2 and the Schematic
Diagram in the July 1995 report, this gaging station is located approximately 7 miles
downstream from the X-V diversion facilities. Only the Buffalo Canal diverts in the intervening
reach. Since the Buffalo Canal, which has a January 29, 1885 priority for 67.5 cfs, is senior
to the X-V water rights and must be satisfied before water becomes available to the X-V
water rights, this arrangement will not injure the Buffalo water right. LA WMA could measure
water at this gaging station any time during April through October, but could not "call" water
to the gaging station when water is contained in the X-V Graham summer storage account.
A small allowance could be made for the return flow from the Buffalo Canal at the gaging
station. The gross amount of water would be limited by the maximum monthly flow rate
shown at the bottom of Table 3 and to maximum volumes of 12,197 acre-feet in anyone year
and to 94,660 acre-feet in any 1 O-year period. Actual credits on this water to apply against
depletions to Usable Stateline Flow would be limited to the consumptive use percentage.
Approximately 10 percent of the water diverted into the X-V Irrigating Ditch for the X-V Ranch
returns to the Arkansas River above the Buffalo diversion facilities; the calls at the Granada
gaging station, therefore, should be reduced by 10 percent, but the consumptive use
percentage should be increased to 64.67 percent.

The Manvel Canal and IrriQation ComDanv

In July 1995, LAWMA owned 300 shares, out of a total of 4,680 shares, of the
Manvel Canal and Irrigation Company. Since that time LAWMA has entered into purchase
contracts with the owners of the remaining shares so that it will acquire the entire water right.
LAWMA plans to devote the entire water right to augmentation; the ditch will be abandoned
and the right-of-way assigned or sold to neighboring land owners.

The canal diverts on the south bank of the Arkansas River about 6 miles east of Lamar.
It extends generally east a distance of about 8 miles and terminates by discharging into the
