Water Quality & TMDLs

  • Little North Fork Coeur d’Alene River and

tributaries impaired by sediment, temperature, and alterations of flow and habitat.

  • Westslope cutthroat trout, sculpin, and other

aquatic life affected.

  • Causes are primarily legacy effects of past

practices.

Water Quality & TMDLs

  • Sediment TMDLs approved by EPA in 2002 set

allocations and identified reductions needed.

  • Temperature TMDLs approved by EPA in 2014.
  • Moose Drool project developed by Forest

Service between 2010-2012, decision signed in 2012.

  • Now, in 4th year of implementation.
  • Supported by WAG.

What is it?

  • Watershed Restoration Project to:
  • Assess,
  • Plan, and
  • Improve the ecological conditions of the upper

Little North Fork Coeur d’Alene River.

slide-8
SLIDE 8

Why do it?

  • Reestablishing structure and function of

ecosystem, including natural diversity

  • Restoring resilient ecosystems
  • Streams do not meet water quality standards
  • High priority for watershed restoration
  • Forest Plan direction

How is it implemented?

  • Roads within 300 ft. of streams recontoured
  • Crossings excavated and culverts removed
  • Remainder of road prism waterbarred
  • Floodplain restoration including dike removal
  • Large woody debris placement
  • Stream channel modification

Before After

  • Crossing excavation
  • Culvert removal
  • Large woody debris

placement

Load Reductions

  • Temperature – now on track to reach targets
  • Sediment

– Chronic and episodic loading reduced 60-99% from treated roads – One estimate: 350 tons/year

Future

  • Work still needed:

– Stream channel work – Road relocation (FR1532)
