Wyo. Stat. § 41-4-510 (2026)

section plans; plans of obstructions; reservoir specifications;
field notes.

The engineer may require, in addition to the maps and plats
above described, a plan showing cross sections at a sufficient
number of points to show the different forms which the ditch,
when completed, will take, and showing what proportion of the
water is to be conveyed in excavation and what proportion to be
conveyed in fill. These plans shall be drawn, or be capable of
being drawn and printed if submitted electronically, on a
horizontal and vertical scale of one (1) inch to twenty (20)
feet. Plans of any dams, cribs, embankments or other proposed
work to obstruct any river, stream, lake or pond, or other
source of water supply, shall be drawn on a longitudinal scale
of not less than one (1) inch to two hundred (200) feet, and for
cross sections on a scale of not less than one (1) inch to
twenty (20) feet; and shall show what material is intended to be
used and placed in such work. Timber, brush, stone or other
material except earth used in such works shall be shown in
detail on a plan, the scale of which shall not be less than one
(1) inch to four (4) feet. The maps of all proposed reservoirs
shall show the surface of the ground under water, and a
sufficient number of lines of level shall be shown so that the
contents of the reservoir or basin may be approximately
determined. If the levels shall be shown by contour lines they
shall be on a scale sufficiently large to show vertical levels
not exceeding five (5) feet, and with all such reservoir plans
there shall be furnished a plan, on a scale of not less than one
(1) inch to four (4) feet, showing the method of providing a
wasteway for such reservoir, and method of drawing off the water
from such reservoir or basin. If the state engineer deems it
necessary he may require the submission of complete plans and
specifications for his approval. He may also require the filing
of field notes of canal and reservoir surveys.
