This page is for summarizing on-wiki resources describing the restoration of Puget Sound River Deltas.
This page is for summarizing on-wiki resources describing the restoration of Puget Sound [[River Deltas]]. 
 
==Methods==
*Among the majority of Puget Sound deltas [[levee or dike setback or removal]] is the primary method of restoration.
*In industrialized systems like the [[Puyallup Delta]] and [[Duwamish Delta]] [[fill removal]] is the primary method of restoration.
*In the [[Deschutes Delta]] [[dam removal]] is the method of restoration.
==Ongoing Projects (updated 7/6/2015)==
*'''[[Skokomish Delta]]
**[[Skokomish Delta Restoration]] - a single page describes all phases.  Phase three involves breaches to a utility access causeway.  Work will be substantively complete in 2015.
*'''[[Snohomish Delta]] - the [[Snohomish Sustainable Lands Strategy]] provides a venue for working on delta restoration issues.  The Snohomish [[Lead Entity]] has a technical workgroup focused on coordination of delta restoration effort.
**[[Qwuloolt Restoration]] - setback levee construction is underway.  First tides anticipated in 2016
**[[Smith Island Restoration]] - Setback levee construction anticipated in 2015, with first tides in 2016 pending resolution of a funding shortfall.
**[[Mid-spencer Island Restoration]] - additional dike removal aims to be coordinated with Smith Island mobilization.
**[[Diking District Six Restoration]] - is a potential project has some design complete.
**[[North Ebey Island Restoration]] - is a potential action that might benefit diking district maintenance.
*'''[[Stillaguamish Delta]]
**[[Leque Island Restoration]] - WDFW has selected a full dike removal alternative, is initiating design, with first tides anticipated in 2017 or 2018.
**[[Matterand Restoration]] - Stillaguamish tribe is completing feasibility work.  No projected completion date.
*'''[[Skagit Delta]] - The [[Farm, Fish and Flood Initiative]] is a local team working on Skagit Restoration issues.
**[[Fir Island Farm Restoration]] - Setback levee construction underway, with first tide anticipated in 2016.
*'''[[Nooksack Delta]]
**[[Lummi Nation Mitigation Bank]] - In development
**[[Lower Nooksack Floodplain Restoration]] - Whatcom County completing analysis consistent with flood planning.
*'''[[Dungeness Delta]]
**[[Three Crabs Restoration]] - reconstruction of Meadowbrook Creek floodplain and nearshore anticipated in 2016.
 
==Past Work==
*[[Nisqually Delta]] - [[Nisqually Refuge Restoration]] and [[Red Salmon Slough Restoration]] are being monitored.  [[Nisqually Delta Distributary Restoration Pre-design]] aims to evaluate options for increasing sediment routing to restored delta plain.
*'''[[Quilcene Delta]]''' - a number of less well documented projects are complete, with the Removal of the South Big Quilcene Levee in feasibility.
*'''[[Skokomish Delta]]''' - [[Skokomish Delta Restoration]] describes three phases of work, with two phases restoring over 300 acres of estuarine floodplain.
*'''[[Skagit Delta]]''' - [[Wiley Slough Restoration]], [[Deepwater Slough Restoration]], [[Fisher Slough Restoration]], and [[Milltown Island Restoration]] have been largely completed.  [[Evaluating salmon rearing limitations in river deltas]] is looking at system scale patterns of fish use affected by restoration in the Skagit.
*'''[[Snohomish Delta]]''' - [[Marysville Mitigation Site]], [[Union Slough Restoration]], and [[Spencer Island Restoration]] are largely complete.  [[Evaluating salmon rearing limitations in river deltas]] is looking at system scale patterns of fish use affected by restoration in the Skagit.
 
 
==Planning and Analysis==
*Many watershed chapters of the [[Puget Sound Salmon Recovery Plan]] identify delta restoration as a limiting factor for the recovery of populations.
*[[Simenstad et al 2011]] describes the historical condition of Puget Sound River Deltas compared to current conditions. 
*[[Fresh et al 2011]] identifies loss of delta wetlands as a significant change in Puget Sound Ecosystems.
*[[Cereghino et al 2012]] proposes a summary analysis of 16 Puget Sound river deltas, and how their historical potential and current degradation might affect how we think about restoraiton of ecosystem processes in those systems.
*[[File:Greene & Beamer 2005.pdf]] provides some evidence of chinook rearing dependance on delta wetlands, which is being extended in an effort [[measuring the density dependance and spatial pattern of juvenile salmon rearing in Snohomish and Skagit deltas]].
*Similar work is underway associated with monitoring following the [[Nisqually Refuge Restoration]].
*[[ESRP]] and [[NOAA RCNW]] are collaborating on a [[River Delta Adaptive Management Strategy]] to support the systematic management of risk and project development that support whole river delta ecosystem restoration and resilience through management of a sequence of river delta capital projects.
 
==Funding and Implementation==
Funding for a large Puget Sound Delta Restoration action typically requires mulitple funding sources to support feasibility, design, construction and evaluation of project work.
*[[Estuary and Salmon Restoration Program]] (ESRP) distributes state capital funds, and
*[[Puget Sound Aquisition and Restoration]] program funds projects defined by the Lead Entity system, and in addition identifies and funds large capital projects including large river delta restoration.
*[[Salmon Recovery Funding Board (SRFB)]] distributes state appropriations that match federal funds from the [[Pacific Coast Salmon Recovery Fund]].
 
==Objectives and Status==
*Individual [[salmon recovery]] plans may have set quantitative goals for river delta restoration.
*As part of the [[Puget Sound Vital Signs]] effort, the [[Puget Sound Partnership]] has set an estuary restoration goal, both to restore a proportion of total historical delta wetlands, and to meet salmon recovery objectives.
*See the pages for individual [[River Delta]] [[sites]] to find out more information about goals and status for specific systems.

Funding for a large Puget Sound Delta Restoration action typically requires mulitple funding sources to support feasibility, design, construction and evaluation of project work.

Objectives and Status[edit]

  • Individual salmon recovery plans may have set quantitative goals for river delta restoration.
  • As part of the Puget Sound Vital Signs effort, the Puget Sound Partnership has set an estuary restoration goal, both to restore a proportion of total historical delta wetlands, and to meet salmon recovery objectives.
