ROCK CREEK DRAINAGE
INTRODUCTION
BACKGROUND
Rock Creek flows out of the east slope of the Bighorn Mountains, beginning on hydrographers’ maps as
the north and south forks of Rock Creek. Three other, smaller tributaries (Sayles, Johnson, and Sand
creeks) join it before it terminates in Clear Creek, which in turn flows into the Powder River. The Powder
River crosses the Montana state line north of Spotted Horse, Wyoming.
CHARACTERISTICS
Rock Creek travels steep slopes in its course, much of which are characterized by mountainous seams and
the subsurface ducts. As a result, water commissioners estimate that losses (or “shrinkage”) to releases
from Willow Park and Cloud Peak reservoirs at 60 percent in a dry year to 40 percent in a wet year. (This
reservoir water, used extensively in Rock Creek, is transferred to the North Fork of Rock Creek through
the Rock Creek & Piney Ditch Co. Canal.)
USAGE
Rock Creek’s diversions are entirely devoted to agricultural irrigation.
Regulation
Water commissioners estimate that regulation is imposed on Rock Creek drainage diversions with the
following timing:
| Wet Year |
Average Year |
Dry Year |
| mid-August |
mid-July |
mid-June |
Even under regulation, Johnson Creek flows 1-2 cfs.
Agriculture
Growers in the Rock Creek drainage tend to devote approximately 60 percent of their lands to alfalfa, 40
percent to grass hay. They have the following irrigation practices:
Percentage of lands served by irrigation type:
| Flood |
Gated Pipe |
Sprinklers |
| 25 |
60 |
15 |
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). Approximately 10 percent of the irrigators using Rock Creek water (the biggest users) practice
post-season irrigation, though they usually do not use their entire right to do so.
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 Rock Creek, 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 |

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.

Notes:
1. Monthly data is from Hydrographers' Annual
Reports for years 1980 and later, and from WRDS for years prior to 1980
2. Zero flow is assumed prior to the first and after the last measurement
3. Monthly data for May-July 1987 is derived from spot measurements in the
Hydrographers' Annual Reports.
4. June & July 1974 data includes interpolated data using WRDS records.

Much of the water carried by this ditch is actually from South Piney Creek.
The maximum appropriation carried by the Lake DeSmet Ditch is approximately
58 percent (54 cfs). The condition of the ditch precludes larger flows. |
| Associated Storage Rights: |
Irrigators on Lake DeSmet Ditch use stored water from Willow and
Cloud Peak reservoirs. |
| Irrigation Practices: |
See introduction to Rock Creek drainage above |
