What is a TMDL?
4 April 11/13, 2017
Implementation Plan for the Powell River and
Tributaries
TMDL – Total Maximum Daily Load
A pollutant “budget” study to determine the maximum amount of a pollutant a water body can receive and still meet water quality standards
A TMDL Includes:
Source Assessment
Modeling
Hydrology
Water Quality
Load Allocation

Components of an Implementation Plan
• Review of TMDL
• Corrective Actions
– Best Management Practices (BMPs), educational programs, regulatory authority, incentives
• Cost/Benefit Analysis
• Measurable Goals
• Timeline to Achieve Water Quality Objectives
– Includes monitoring plan to assess progress
• Public Participation

• Fecal Bacteria in the Powell River and Tributaries
– What’s Fecal Bacteria?
• Bacteria associated with feces from humans and warm blooded animals
• (fecal coliform, E. coli)
– Why should stakeholders care?
• Pathogens (including some strains of E. coli)
• Parasites
– Water Quality Standard
• Primary contact recreation - swimming
• Single Sample Max: 235 cfu/100 ml E. coli (10% violations allowed)
• Monthly Geometric Mean: 126 cfu/100 ml E. coli

• How healthy is the benthic macro-invertebrate
community?
– Benthic (on the bottom)
– Macro (visible without a microscope)
– Invertebrate (no backbone)
• How many bugs/critters on the bottom of the
stream? And what kind?
• General indicator of water quality.
