Middle Creek AVF Reconnaissance
Level Survey
Map Exhibit AVF-2 delineates the probable extent of
unconsolidated alluvium associated with Middle Creek
and its tributaries. The peecentage of the indicated
alluvium deposited by stream flow versis'general outwash
talus and aeolian deposition is unknown. However, it
seams likely that the immediate area to the stream proper
is largely stream laid. It is also likely that if a
strict determination was to be made including only stream
laid deposits -- the actual area of AVF would be narrower
than indicated,
Judging from the generally poor vegetative cover
within the indicated area, effective sub-irrigation at
sufficient altitude to benefit plant growth is minimal.
A high percentage of the cover in the indicated area
consists of sagebrush. Another indication suggesting
poor sub-irrigitation is that although the areas adjacent
to the mapped AVF have been and are used as agricultural
land, little agricultural use is being made of the AVF
area proper.
The majority of the area adjacent to the Middle
Creek AVF is undeveloped range land. There are two
exceptions to this category, one of which may be considered
mixed rangeland. This is labeled sage fi grass on Exhibit
AVF-2. It consists of a mixture of more than one-third
shrub or bush in with naturally occuring grasses.
The second exception consists of the three areas
labeled Hay(1), Hay(2), and Aay(3) on exhibit AVF-2. These
exceptions may be described as one of the following:
1. Cropland in soil improvement grasses
2. Cropland used only for pasture in rotation with
crops
3. or pasture o.n land more or less perminately.used
for that purpose.
These altering states of description are based on a
number of factors such as:
1. How much livestock the rancher owns
2. The physical state of the rancher
3. The mental state of the rancher
4. The whimsical outlook of the rancher toward
future markets and the impending winter.
The areas marked-Hay(2) and Hay(3) are not irrigated.
Area Hay(1) is irrigated by two ditches that are cut off
of the Little Middle Creek drainage. The potential exists
for flood irrigation in area Hay(2). However, additional
irrigation ditches would have to be cut. Area Hay(3) lies
at an elevation such that it is doubtful that sufficient
water exists in any of the middle creek tributaries at the
required head-gate elevation.
