Stream Monitoring Questions

The stream monitoring program originally designed to answer four questions:

1. Has storm and/or base flow stream water quality changed over time?

2. Is there a spatial difference in storm and base flow water quality conditions?

3. What is the human health risk from stream water quality?

4. Do current (or future) King County facilities impact stream water quality?

Routine Ambient Stream Water Quality Monitoring – Analytical Parameters20 sites sampled monthly (56 sites pre 2009)

• Bacteria (Fecal Coliform)• Temperature• Nutrients (OP, TP, TN, ammonia, nitrate+nitrite)• Oxygen• pH• Turbidity• Conductivity• Total Dissolved Solids• Eliminated quarterly metals, silica, TOC/DOC, turbidity,

and E. coli analysis in 2009

Example of Water Quality Trend Analysis

Water Quality Index (WQI)• Integrates 8 water quality parameters into a

single number (FC, temp, pH, DO, TN, TP, TSS, Turbidity)

• Developed by EPA, modified by Ecology and calibrated for Puget Lowland Streams.

• Unit less number 1-100 (>80 low concern; 80-40 marginal

concern and <40 highest concern)

• WQI recently updated to reflect more stringent temperature WQC to protect salmon

• Some limitations to WQI- limited parameters, can over or underemphasize problems

Stream Wet Weather Monitoring

• Sampling trigger - preferably ≥ 0.25″ rain with 24 hr antecedent dry period;

• Wet-weather samples collected from 20 streams; • Target 4 events (2 Nov - Mar; 1 Apr - Jun; 1 Aug - Oct)

• Analysis includes all parameters measured during routine sampling, as well as low-level metals and organic compounds.

Stream Sediment Contaminant Monitoring Program

• Program initiated in 1987 – primarily measured metals at stream mouths

• 2003 trend analysis suggested program updates necessary

• 2004 - Program revised – Parameters added (organics, organic carbon, AVS/SEM)

– 10 Trend Locations– 27 Rotating Basin Characterization Streams –

sample approx. every river mile (approx. 20 samples yr 2004-08; 10 samples yr 2009)

Stream Sediment Monitoring Program Questions

• Do chemical concentrations in stream sediment exceed sediment quality guidelines or thresholds?

• How does sediment quality change over time?

• Does sediment quality differ within or between stream basins?

Stream Sediment Monitoring Sampling Locations

•Data compared to freshwater sediment guidelines

Data up to 2007

Benthic Macroinvertebrate Sampling Locations• ~ 140 Sampling locations;

• Samples collected annually from ~10 randomly-selected sites in each of 15 sub basins in WRIAs 8 and 9;

• Sampling initiated in 2002 -present (except 2004);

•Puget Lowland Benthic Index of Biotic Integrity (BIBI) used for primary data analysis tool;

•Data presented in Kingstat.

Benthic Macroinvertebrate Monitoring Questions

1. Do watershed sub-basins within the Greater Lake Washington Watershed (e.g. Bear Cr, Issaquah Cr, Lower Cedar Tribs etc.) and Greater Green-Duwamish (e.g. SoosCr, Newaukum Cr, Jenkins/Covington Cr, etc.) differ in terms of biological condition?

2. Is the biological condition improving (or declining) over time? Is the trend significant?

3. Do land use patterns measured at the sub-basin level affect biological conditions differently within the watershed
