Aquatic Invertebrates - Thornton Creek Restoration Project Effectiveness Monitoring

NOAA has designed and is currently implementing a hyporheic monitoring plan for the Thornton Creek watershed in North Seattle. This work is being conducted for Seattle Public Utilities, who in 2015 completed two large-scale floodplain reconnection projects in the Thornton Creek Watershed. This study will evaluate restoration effectiveness by comparing control and treatment study reaches to each other and to forested references streams before and after restoration. NOAAs data collection focuses on hyporheic invertebrates, water temperature, and nutrient concentrations.

Taxonomic and density data for aquatic invertebrates collected at project sites.

Data collection is still ongoing and data not yet ready for dissemination. At this time, contact the Data Manager for information on obtaining access to this data set. In the near future, the NWFSC will strive to provide all non-sensitive data resources as a web service in order to meet the NOAA Data Access Policy Directive (https://nosc.noaa.gov/EDMC/PD.DA.php).

QA/QC procedures applied by professional taxonomist. These data were collected and processed in accordance with established protocols and best practices under the direction of the projects Principal Investigator. Contact the dataset Data Manager for full QA/QC methodology.

Project was funded by non-federal agency. Unclear at what point they will choose to make data publicly available.

The Northwest Fisheries Science Center facilitates backup and recovery of all data and IT components which are managed by IT Operations through the capture of static (point-in-time) backup data to physical media. Once data is captured to physical media (every 1-3 days), a duplicate is made and routinely (weekly) transported to an offsite archive facility where it is maintained throughout the data's applicable life-cycle.

Samples sent to professional invertebrate taxonomist for identification and enumeration.
