CLEAR CREEK DRAINAGE
INTRODUCTION

BACKGROUND

Clear Creek flows out of the east slope of the Bighorn Mountains, gathering French, Piney, Rock, Double Crossing, Bull, and Sand creeks in addition to its own North, South, and Middle forks. It finally joins the Powder River well north of Arvada, Wyoming. The Powder River crosses the Montana state line north of Spotted Horse, Wyoming.

CHACTERISTICS

Losses on upper Clear Creek are low, thanks to the stream.s steep descent to the foothills of the Bighorn Mountains. But it becomes a slow-moving, relatively high-loss stream just before it enters Buffalo. Releases from Lake DeSmet are calculated to take 33 hours to reach Pratt & Ferris No. 3, the first diversion downstream from Clearmont. Clear Creek also passes through Buffalo and Clearmont. The slower velocities and meanders of the lower elevation passage and low-volume pumps tapping Clear Creek.s flows through the two towns contribute to its losses; its storage (see below) helps ameliorate much of this for irrigators. Nevertheless, water commissioners work carefully with irrigators to ensure that Clear Creek normally dries up at least twice before it can reach the Powder. Return flows recharge the creek.s flows downstream of Pratt & Ferris No. 3 enough to provide flows for the Kendrick Canal, which in turn diverts all of the creek.s flows.

Clear Creek drainage also contains many transbasin diversions. Four Lakes diversion moves water out of Clear Creek into its tributaries through French Creek, then to Penrose to deliver the water to Johnson Creek (a tributary of Rock Creek, which is a tributary of Clear Creek), where the water is used.

USAGE

Clear Creek.s diversions are used primarily by agricultural irrigation, but also find municipal, industrial, and recreation uses.

Regulation

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

Wet Year Average Year Dry Year

mid-August mid-July mid-June

Wet Year	Average Year	Dry Year
mid-August	mid-July	mid-June

Agriculture

Growers in the Clear Creek drainage tend to plant acreage in the following pattern:

45 percent alfalfa
30 percent grass hay
10 percent grains
15 percent corn

The grains (usually barley or oats) are used to rejuvenate the soil after approximately five years of alfalfa/grass growth. Corn is used as a silage crop.

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 40 percent of the irrigators practice post-season irrigation, though they usually do not use their entire right to do so.

Irrigation Practices

Type of irrigation Percentage of irrigated land

Ditch-flood 65

Gated pipe 15

Sprinkler 20

Type of irrigation	Percentage of irrigated land
Ditch-flood	65
Gated pipe	15
Sprinkler	20

Water commissioners calculate the .shrinkage,. or instream loss from reservoir requests depending on the distance between the reservoir and diversion. In general, for Clear and Rock creeks, irrigators are charged approximately one percent loss per mile of travel from reservoir release to headgate, as long as the headgate is upstream of Lake DeSmet. The system changes there. A summary of the major reservoir shrinkage schemes used by the water commissioners follow:

Lake DeSmet

DeSmet.s shrinkage is experientially based for each headgate downstream from the reservoir. Numbers are essentially independent of the amount of water available to the system in any given year:

Willow Park and Cloud Peak Reservoirs

Irrigators requesting water from rights in Willow and Cloud Peak reservoirs are assessed flat shrinkages depending on location. Water commissioners estimate the shrinkage based on distance downstream from the high-elevation reservoirs:

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 Clear Creek, this practice is limited primarily by the condition of ditches that follow the diversions from the creek. 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

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: FOUR LAKES & FRENCH CREEK DITCH DIVERSION
Four Lakes & French Creek headgates

Date: 18 Oct. 2000

Diversion Description: Headgate consists of two, 5.5 x 13.5-foot rectangular steel gates in steel slider raised/lowered by Waterman-type screws mounted in a corrugated steel headwall.

Diversion Location: The Four Lakes & French Creek Ditch diversion is located on the North Fork of Clear Creek and diverts water to Johnson Creek (a tributary to Rock Creek) through French Creek and Penrose Ditch.

Headgate:

Lat. Long.

N 44° 20' 15.9'' W 106° 59' 56.6''

Flume:

Four Lakes & French Creek flume

Conveyance Description: Open channel canal, approximately 2 mi. long.

Note: Permit No. 2492E is adjudicated from Clear Creek to Moeller No. 3 and Robbin.s ditches from French Creek.
Because Four Lakes diverts water from one tributary of Clear Creek to another (North Fork to French Creek), the waters destined for Johnson Creek are for supplemental supply, making those flows officially 0 cfs. But because Johnson Creek.s direct flow is notoriously poor, this supplemental supply is put to maximum use for most of the season. As a result, the flow destined for Penrose Ditch and Johnson Creek can reasonably be calculated using the Wyoming State Engineer.s Office baseline allocation:
1 cfs/70 acres * 144.04 acres = 2.06 cfs

The supplemental supply summary follows:

Permit Priority Date Permitted Use Acres Flow (cfs) Cumulative (cfs)

4731E 01-28-1931 I 62.92 0 0

4731E 01-28-1931 I 81.12 0 0

Associated Storage Rights: None

Irrigation Practices: See introduction to Clear Creek drainage

Agricultural Practices: See introduction to Clear Creek drainage

Return Flows: Estimated percentage of total diversion developing into return flows:

Losses: Typical (10 percent) by the end of the ditch
