Nearshore Strategies Data Report
Cereghino et al 2012 completed a soundwide analysis to identify and describe river delta sites in Puget Sounds as part of a nearshore ecosystem restoration strategy (using remote sensing data c. 2000-2006). The following narrative of this delta site was developed to support distribution and use of analysis results:
- The Dungeness Delta in the Juan de Fuca Sub-basin historically contained 297 acres of vegetated wetland along a 12 km shoreline. The delta receives flow from a 54,761 square kilometer watershed. These characteristics make this system the 10th largest delta out of 16 systems in Puget Sound.
- Simenstad et al 2011 found that this system had lost 30% of its vegetated tidal wetlands, and 51% of its shoreline length. Of the remaining shoreline, 44% shows some evidence of infrastructure development. In the surrounding uplands, 20% of land is estimated to have greater than 10% impervious surface. Across the watershed, 24% of land is estimated to have greater than 10% impervious surface. Based on these paramters, the site was given a degradation score of 37 out of 100, making it the 9th most degraded delta in Puget Sound. It faces a low risk of future development locally, and a low risk of development across the watershed. None of the watershed is currently impounded behind dams.
