Or. Admin. Code § 690-076-0010 - Definitions
The following definitions apply to OAR 690-076-0005 to 690-076-0035.
(1) "Affected Local
Government" means any local government as defined in OAR 690-005-0015, within
whose jurisdiction a minimum perennial streamflow is proposed or
established.
(2) "Basin" means any
one of the major drainage areas identified by the Commission for program
planning and management purposes. Basin boundaries are identified on Water
Resources Department map 0.6.
(3)
"Classification" means the designation in basin programs of allowed and
preferred beneficial uses of a specified water source as provided in ORS
536.340. A classification may
also reserve quantities of water for preferred beneficial uses.
(4) "Commission" means Water Resources
Commission.
(5) "Department" means
Water Resources Department.
(6)
"Director" means Water Resources Director.
(7) "Minimum Perennial Streamflow", also
minimum streamflow, means an administrative rule that establishes a flow
necessary to support aquatic life or minimize pollution. The rule includes a
priority date and specifies streamflow levels for all or any period of the
year. It establishes priority for instream use over future appropriations and
identifies flow objectives for future management in streams where shortages
occur. The Commission will assume minimum streamflow levels are most
appropriate for support of aquatic life if the flows are the lowest level
which, if maintained, would support a population of key fish species consistent
with the management objectives of Oregon Department of Fish and Wildlife. The
Commission will assume minimum streamflow levels are most appropriate for
minimizing pollution if the flows are the lowest level which, if maintained,
would assure that projected loading levels from adequately treated wastes and
best management practices for non-point sources would not result in violation
of water quality standards of the Department of Environmental
Quality.
(8) "Planned" means a
determination has been made for a specific course of action either by
administrative or budgetary action of a public body or by engineering, design
work, investment toward construction or application for a development permit
from the private sector.
(9)
"Potential" means an option which could reasonably occur in the future but is
not planned. A feasibility determination may or may not have been completed,
but the option has not been ruled out.
(10) "Subbasin" means any subarea of a basin
defined by surface drainage patterns such as the drainage basin of any
tributary, or the area draining to any point on a river, or draining between
two points on a river.
(11)
"Withdrawal" means an administrative rule prohibiting all new appropriations
for particular uses from a source for part or all of the year as provided in
ORS 536.410. A withdrawal can be set
for a prescribed length of time or indefinitely until modified or revoked by
the Commission.
