POWDER RIVER DRAINAGE
INTRODUCTION
BACKGROUND
The Powder River begins in the east face of the Big Horn Mountains, gathering numerous tributaries from
the southeastern face of the mountains to the Powder River Basin. It eventually crosses the Wyoming-
Montana border just southwest of Moorehead, Montana, carrying water from Crazy Woman, Spotted
Horse, Clear, Wild Horse, Fortification, and Buffalo Creeks. The Powder River drainage covers the
majority of the geography in the Powder/Tongue Basin, but much of the land it crosses has little
agricultural value. As a result, much of the Wyoming consumptive use for the Powder is restricted to the
Powder’s southern reaches, near its source in the Middle, Red Fork, and North Fork tributaries.
CHARACTERISTICS
As its name implies, the Powder River flows through very erodable soils. They can be found on either
side of the North, Red, and Middle forks where the streams leave their canyons. The tributaries of the
Powder have little high mountain country and little forested watershed to regulate its flows. As a result,
rains can mean “flashy,” damaging floods capable of disabling diversions. Also, unlike the other
drainages on the East Slope of the Big Horns, the Powder has its oldest and best water rights up at the
mouths of the tributary canyons, rather than down in the lower plain. Finally, irrigators have learned that
the sediment load in the Powder quickly wears out pumps. Though sprinklers have higher efficiencies,
most irrigators on the Powder do not use them.
The North Fork is the only tributary favored with storage above the water users (Dull Knife Reservoir). It
is also the tributary that feeds the mysterious “sinks” in its canyon. These subterranean aqueducts to the
Madison formation tap an unknown amount of water from the North Fork before it can reach the USGS
gaging station at the mouth of the canyon. Water commissioners have learned to keep the sinks full or risk
spending much precious time in regulation waiting for Dull Knife’s releases to fill the sinks before
irrigators below see requested increases in flow.
USAGE
The Powder River’s diversions are entirely devoted to irrigation.
Regulation
Water commissioners estimate that regulation is imposed on Powder River drainage diversions with the
following timing:
| Wet Year |
Average Year |
Dry Year |
|---|
| none |
Third week of July |
First week of July |
Because irrigators on the Powder tend to cooperate among themselves, regulation on the Powder is rare.
In general, irrigators rotate their usage as much as possible, allowing each other to use full appropriations
much later in the season than they could if they didn’t cooperate.
Agriculture
Growers in the Powder River drainage tend to devote approximately 85 percent of their lands to alfalfa,
10 percent to grass hay, and five percent to oats.
50 years ago, the split was approximately the same, but growers produced more out of dependence on
what they grew. As a result, they tended to plant all possible lands. Today, because transportation and a
shift in the focus of economics in the region make landowners less dependent on what they produce,
irrigators are less likely to develop every acre available.
To deliver water from their diversions, they have the following irrigation practices:
Percent of lands irrigated by irrigation practice:
| Flood |
Gated Pipe |
Sprinklers |
| 95 |
2 |
3 |
The typical irrigation season runs from April 15-May 1 (depending on whether the spring runoff is
delayed by colder weather) to early/mid October (depending on when the first snows fall and the ground
freezes). Powder River users do not typically use post-season irrigation.
Double Appropriation
Irrigation water rights with priority dates of March 1, 1945 or earlier are entitled to an additional 1cfs per
70 acres under Wyoming’s surplus water statutes. Whenever the supply in a stream exceeds to amount
required to satisfy all existing appropriations established prior to March 1, 1985, the stream is said to be
in an excess flow condition and water right holders with priorities between March 2, 1945 and March 1,
1985 may use an additional 1 cfs for each 70 acres irrigated.
In the Powder River, this practice is limited primarily by the condition of ditches. Many of the ditches are
not capable of carrying all of the water an irrigator could use.

WATER RIGHTS
Two water rights summary tables are provided for each diversion serving irrigation referenced here. The
first, included in the body of the diversion synopsis, refers to the rights on record with the State
Engineer’s Office and is derived from that office’s Tabulation of Adjudicated Surface Water Rights of the
State of Wyoming, Water Division Number Two (Oct. 1999).
Because this rights summary is pulled directly from the SEO Tab, the rights cited follow the SEO’s
priority order:
| Hierarchy |
Format of right |
Example |
|---|
| 1 |
Day, Month, Year |
05-15-1884 |

Board orders or court orders may also establish a specific priority.
Irrigated Lands Water Rights Database
The second table, which follows the diversion synopsis, is taken from the irrigated lands water rights
database developed for the basin plan. It can be used as a reference with the following caveats: It only
lists water rights associated with the irrigated lands polygons mapped by HKM. The table does not
include nonirrigation rights devoted to reservoir supply, municipal, fish propagation, etc. The rights on
this table are associated only with those irrigated lands identified through the course of this study, both
actively irrigated and currently idle.

Much of the land irrigated by this ditch is served by sprinklers, which
reduce return flows. |
| Losses: |
This ditch crosses the red, sandy soil that gives the Powder River its
distinctive hue and opacity and areas of bentonite. Though the bentonite
seals the ditch walls and floor, the red soil tends to seep water. Losses on
the Big Four Ditch are approximately 35 percent by the end of the ditch |

KEY DIVERSIONS
| Diversion: |
SAHARA DITCH DIVERSION
AKA: Sussex Irrigation Canal |
| Date |
5 Jan. 2001 |
Sahara Headgate |
| Note: |
The double flumes used to measure flow in this creek appear to be
undersized and submerged, making accurate measurements difficult. |
| Diversion Description: |
Headgate consists of two hydraulically operated, 3.8 x 4.2-foot
rectangular steel gates in steel sliders mounted in concrete headwall. One
of the actuator arms appears to be bent. Water commissioners report that
the gate is not adjusted, but left open in its present condition. |
| Diversion Location: |
The Sahara Ditch diversion is located on the main stem of the Powder
River and is the lowest monitored diversion on the river. |
|
| Headgate: |
| Lat. |
Long. |
| N 43° 41' 33.6'' |
W 106° 31' 53.0'' |

|
Sahara flumes |
| Conveyance Description: |
Open channel canal, approximately 14 mi. long. It is siphoned across the
Powder River in one instance, providing a bottleneck to flows. |

| Return Flows: |
Often, the bentonite-charged runoff is allowed to flow into this ditch to
seal leakage. SEO personnel were not able to estimate return flows other
than to estimate that they would be minimal because the ditch diverts
water so far from the river. Much of the acreage irrigated is underlain by
gravel. |
