Idaho Admin. Code r. 37.03.07.010 - DEFINITIONS
01.
Alteration . To obstruct,
diminish, destroy, alter, modify, relocate or change the natural existing shape
of the channel or to change the direction of flow of water of any stream
channel within or below the mean high water mark . It includes removal of
material from the stream channel and emplacement of material or structures in
or across the stream channel where the material or structure has the potential
to affect flow in the channel as determined by the director .
(3-18-22)
02.
Applicant . Any individual, partnership, company, corporation,
municipality, county, state or federal agency, their agent, or other entity
proposing to alter a stream channel or actually engaged in constructing a
channel alteration , whether authorized or not. (3-18-22)
03.
Base Food Elevation . The
Base Flood (BF) is referred to as the one hundred (100) year flood and is a
measure of flood magnitude based on probability. The BF has a one percent
chance of occurring or being exceeded in any given year, with the Base Flood
Elevation (BFE) being the level of flooding reached during the BF or the one
hundred (100) year flood event. (3-18-22)
04.
Board . The Idaho Water
Resource Board . (3-18-22)
05.
Continuously Flowing Water . A sufficient flow of water that could
provide for migration and movement of fish, and excludes those reaches of
streams which, in their natural state, normally go dry at the location of the
proposed alteration . IDWR will assume, subject to information to the contrary,
that the USGS quadrangle maps accurately depict whether a stream reach is
continuously flowing, at the location of the proposed alteration . Such
exclusion does not apply to minor flood channels that are a part of a stream
which is continuously flowing in the reach where the alteration is located.
Also, such exclusion does not apply to streams which may be dry as a result of
upstream diversion or storage of water. (3-18-22)
06.
Department . The Idaho
Department of Water Resources. (3-18-22)
07.
Drop Structures, Sills and
Barbs. Physical obstructions placed within a stream channel for the
purpose of stabilizing the channel by decreasing stream gradient and velocity
and by dissipating stream energy. (3-18-22)
08.
Director . The Director of
the Idaho Department of Water Resources. (3-18-22)
09.
Human Life Support System .
Any artificial or natural system that provides all or some of the items (such
as oxygen, food, water, control of temperature, or disposition of carbon
dioxide) necessary for maintaining human life or health. (3-18-22)
10.
Mean High Water Mark . As
defined in Idaho Code, §
42-3802(h), the
mean high water mark is water level corresponding to the "natural or ordinary
high water mark" and is the line which the water impresses on the soil by
covering it for sufficient periods of time to deprive the soil of its
terrestrial vegetation and destroy its value for commonly accepted agricultural
purposes. (3-18-22)
11.
Non-Powered Equipment . Equipment which is powered only by human
strength. (3-18-22)
12.
Plans . Maps, sketches, engineering drawings, photos, work
descriptions and specifications sufficient to describe the extent, nature, and
location of the proposed stream channel alteration and the proposed method of
accomplishing the alteration . (3-18-22)
13.
Powered Equipment . Equipment
which is powered by means other than human strength such as a gasoline engine
or electric motor. (3-18-22)
14.
Repair . Any work needed or accomplished, to protect, maintain, or
restore any water diversion structure and the associated stream channel
upstream and downstream as necessary for the efficient operation of the water
diversion structure. (3-18-22)
15.
Stream Channel . A natural water course of perceptible extent with
definite beds and banks which confines and conducts continuously flowing water .
The channel referred to is that which exists at the present time, regardless of
where the channel may have been located at any time in the past. For the
purposes of these rules only, the beds of lakes and reservoir pool areas are
not considered to be stream channels. (3-18-22)
