Quality Assurance Project Plan: Status and trends monitoring of small streams in the Puget Lowlands ecoregion for Stormwater Action Monitoring (SAM)
June 30, 2020
This Quality Assurance Project Plan (QAPP) details a long term status and trends monitoring study for small streams in the Puget Lowland as part of Stormwater Action Monitoring (SAM) program. SAM is the regional stormwater monitoring program funded by the Phase I Municipal Stormwater permit and the Western Washington Phase II Municipal Stormwater permit permittees.
This study of small streams in the Puget Lowland Ecoregion (called Puget Small Streams, PSS study, or SAM_PSS study hereafter) is designed to answer the question, “Are regional conditions in receiving water quality and biota improving in concert with broad implementation of required stormwater management practices?”
In 2015, the first round of monitoring evaluated the condition (status) of streams (DeGasperi et al., 2018). Beginning in 2020 and thereafter this study will monitor streams’ changes over time in
urban, urbanizing and rural areas of the Puget Lowland.
The PSS will follow the protocols developed for the on-going statewide stream health monitoring
program-Status and Trends Monitoring for Watershed Health and Salmon Recovery (WHSR) for
physical habitat, biological measurements, except for minor changes to water quality parameters
to better capture the stormwater-related chemistry signals. In addition this effort will sample
sieved sediments for stormwater-related chemistry signals.
This QAPP ensures quality data collection, analysis, reporting and management of the SAM PSS monitoring study
