Purpose of Project
• Provide Status and Trends data and
analysis to help understand the
effectiveness of the WRIA 8 Salmon
Recovery Plan
• Evaluate assumptions related to
hydrology, biology, and riparian conditions
across a range of land cover and land use
types
• Evaluate methods and develop metrics to
be used to assess the health of streams
across Puget Sound

Deliverables
X
• $995,716 awarded from EPA in 2010
• $335,934 match (WRIA 8 and King County)
Approach
• 50 sites in WRIA 8
(random)
• 10 sites across Puget
Sound (sentinel)
• Measure:
– Flow
– Land Use/Land
Cover
– Biological Indicators
– Aquatic and
Riparian Condition
Hypotheses
• H1: If effective impervious cover influences hydrology, then
urbanized streams with impervious cover connected to streams will
experience higher peak flows than systems with less connected
impervious area.
• H2: If hydrology influences biological conditions in streams, then the
BIBI and FIBI metrics will be lower in streams that exhibit flashy
flows caused by more connected impervious cover.
• H3: If land use type influences fluvial geomorphology, then the
frequency of pools will be different in each land use type.
• H4: If the salmon recovery plan in WRIA 8 is successful, then the
pool frequency will increase in basins where restoration actions are
prescribed.

Stream flow
• A work in progress
• We have established 6 new gauges and
have 30+ existing gauges co-located with
sampling reaches
• We will be using established metrics to
evaluate our hypotheses
Land use/Land cover
2005
2010
• Looking at changes in land cover over time (see 2011 report)
• Using land use classification to better describe how landcover
influences salmon recovery and to understand basin scale
conditions
Deliverables
• Final Report to EPA describing the
relationship between stream flow, aquatic
habitat, and biological integrity across
land use types in WRIA 8 and 10 sites
across Puget Sound
• Report on the status and trends of 50
stream reaches across WRIA 8
Summary
•
•
•
•
Year 3 in a 5 year study
Currently sampling 57 sites annually
%pools is considered good for ~1/3 of our sites
Tier 1 streams are in the “fair” and “good”
categories
• Wide range in FIBI across watershed following
pattern across Tiers similar to BIBI
• Flow
• Land cover change analysis shows losses in
UGA.
