2.04.7 Hydrology Description
The Applicant diverts water from Hubbard Creek for agricultural and
industrial uses through the Deer Trail Ditch all year.
There are four well defined watersheds (gulches) that are tributary to
Hubbard Creek. They flow generally from west to east into Hubbard Creek.
They are characterized by steep to nearly vertical canyon walls. All four
gulches have well developed colluvial deposits within their streambeds.
From south to north the gulches are known as 1) Freeman Gulch; 2) Sheep
Corral Gulch; 3) Dove Gulch; and 4) Iron Point Gulch. Freeman Gulch is
typically dry with only one flow event noted in monitoring results from June
1995 through November 1997 and that was in June 1997 during a significant
precipitation event.
Lower Sheep Corral Gulch and Lower Dove Gulch are also expected to be
typically dry with flow occurring during spring snowmelt and after significant
precipitation events. Lower Dove Gulch has been dry during all monitoring
events from the late 1997 field reconnaissance through 2009. Small almost
insignificant flows (maximum 13.6 gpm) have been recorded at Lower Sheep
Corral on seven occasions during the 1997 through 2009 monitoring
program.
Freeman Gulch and Sheep Corral Gulch are ephemeral drainages. Dove
Gulch is an intermittent stream. A Dove Gulch Hydrology Report is
presented in Volume IIIA, Exhibit 19. Iron point gulch is an intermittent
stream. Following are flow measurements taken from October 1999 through
October 2009 at Iron Point Gulch's confluence with Hubbard Creek. All other
monitoring events were recorded as dry.

Terror Creek is a perennial stream which drains approximately 29 square
miles (18,560 acres). The dendritic drainage pattern of tributary streams
may be modified in part by geologic structures fracture zones or faults.
