CRAZY WOMAN CREEK DRAINAGE
INTRODUCTION

BACKGROUND

Crazy Woman Creek drains the east slope of the Big Horn Mountains in northeast Wyoming. Between the Clear Creek drainage to the north and the forks of the Powder River to the south, Crazy Woman converges the North, Middle, and South forks of Crazy Woman and Muddy Creek to meander across the Powder River Basin until it joins the Powder River south of Arvada. The Powder collects Clear Creek downstream before it enters Montana north of Spotted Horse, Wyoming.

CHARACTERISTICS

The Crazy Woman drainage represents the only court-adjudicated stream in the Northeast Wyoming and Powder/Tongue River Basins. In many cases, the court’s July 5, 1889 ruling was based on assessments of ditch capacity that the diversions cannot carry. The Second Judicial District gave all the diversions priority independent of date, assigning a priority number rather than a priority date. As a result, the 31 diversions affected by the decree have priority numbers; rights granted by the State Board of Control since the decree have the priority date and a permit number that can be found elsewhere in Wyoming. In the past century, most of diversions of Middle Fork and across the Interstate have been changed to the 1 cfs per 70 acres of irrigated land used by default by the State Engineer’s Office.

Since the decree, State Engineer’s Office hydrographer/commissioners have attempted to bring the rights on Crazy Woman to the 1 cfs/70 acre default established in Wyoming whenever they could. As a result, many of the lands affected by the original decree keep their priority number but are watered by 1 cfs/70 acres. Hydrographer/commissioners detailed the adjudicated right and maximum diversion of recent record for this memorandum:

USAGE

Crazy Woman Creek is devoted to agricultural irrigation and industrial uses.

Losses en route from the Muddy Guard reservoirs depend on the diversion’s distance from the reservoir outlets. Water commissioners charge from 10-25 percent “shrinkage” (Instream or conveyance losses) on this water. Essentially, commissioners estimate shrinkage necessary to fully serve the first right on the stream, the Smith Ditch.

Regulation

Water commissioners estimate that regulation is imposed on Crazy Woman Creek drainage diversions with the following timing:

Wet Year	Average Year	Dry Year
None or last of Aug	2nd week of July	2nd week of June

Agriculture

Growers in the Crazy Woman drainage tend to devote approximately 50 percent of their lands to alfalfa, 25 percent to grass hay, 10 percent to grains, and 15 percent to corn. The grains (barley and oats) are used to replenish the soil after alfalfa has been grown and harvested on the field for approximately six years. Corn is used in silage operations. Irrigation practices are broken out according to significant diversion below. In many places on the drainage, a Natural Resource Conservation Service (NRCS) project in 1992 increased sprinkler usage considerably.

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 Crazy Woman 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 the 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 Crazy Woman 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	05-15-1884
2	Month and Year	05-00-1884
3	Specified Season and Year	Spring 1884
4	Year Only	1884
5	Before Year	Before 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.

KEY DIVERSIONS

Diversion:	KENNEDY DITCH DIVERSION AKA: Crazy Woman #16	Kennedy headgates
Date:	25 Oct. 2000
Diversion Description:	Headgate consists of a single, 3.5 x 3.5-foot round steel headgate in good condition, raised/lowered by a Waterman-type screw mounted on steel slides in a concrete headwall.
Diversion Location:	The Kennedy Ditch diverts from the North Fork of Crazy Woman, a tributary of Crazy Woman Creek, which in turn joins the Powder River.
	Headgate: Lat. Long. N 44° 10' 42.6'' W 106° 44' 18.2'' Flume: Lat. Long. N 44° 10' 41.5'' W 106° 44' 13.5''	Kennedy flume
Conveyance Description:	Approximately 2 miles long, includes one mile of underground pipe (Kennedy pipeline right comes from larger Kennedy Ditch right)
Direct Flow Water Rights:	The direct-flow rights summary follows: Permit Priority Date Permitted Use Acres Flow (cfs) Cumulative (cfs) 16 I 0 32 32 26 1/2 I 0 13 45
Associated Storage Rights:	Fills reservoirs 7305R and 6417R. Irrigators on the Kennedy Ditch also use water from Muddy Guard No. 2 Reservoir.
Irrigation Practices:	Irrigators use approximately one-third side-roll and pivot sprinklers, one-third gated pipe, and one-third ditch flood irrigation.
Return Flows:	Estimated percentage of total diversion developing into return flows:
	Destination Wet yr. Mid yr. Dry yr. Crazy Woman Creek 3 5 7
Losses:	Typical (10 percent) by the end of the ditch
