TMDL Development Process
• Identify water quality concerns
• Determine loading capacity and excess load
• Identify pollution sources and conditions contributing to
water quality concerns
• Point sources
• Nonpoint sources
• Link sources and conditions to water body
• Allocate pollutant loads that when implemented will result
in water quality standard attainment

TMDL and WQMP Implementation Process
DMAs (DEQ)
• DMA’s submit TMDL IP’s
for DEQ review and
action
• DMAs submit annual
reports to DEQ
• DEQ reviews TMDL
Implementation Plans for
effectiveness
• DEQ may require plan
revisions
ODA
• ODA reviews and
revises area plans and
rules every two years
• DEQ reviews and
provides comment
• EQC may petition ODA
for changes
ODF
• ODF and Board of
Forestry administer
the Oregon Forest
Practices Act
• DEQ reviews and
provides comment
on FPA rules
• EQC may petition
Board for changes,
Board can petition
EQC to reconsider

Rogue Basin Temperature TMDLs:
Waters Covered and Shade Allocations
• Applegate Subbasin (2003): All streams (& a Sediment
TMDL)
• Bear Creek Watershed (1992/2007): All perennial &
intermittent streams (& a Sediment TMDL)
• Lobster Creek (2002): Perennial streams
• Sucker Creek (2002): All streams
• Rogue River Basin (2008): All perennial and intermittent
streams
• Shade Allocations: Effective Shade @ System Potential
Vegetation

is forested
• Significant streamside
range, agriculture, and
urban areas
• Forested area is a mix
of federal and private
land

Mapping Designated Management Agencies
(DMAs) and Responsible Persons
• DMA: “a federal, state or local governmental
agency that has legal authority over a sector or
source contributing pollutants, and is identified as
such by the Department of Environmental Quality
in a TMDL.”
• Mapping helps DEQ with source identification,
and
• Links responsible entity to TMDL load allocations
