Dieckman Slough is a side channel of the Lower North Santiam River, just downstream of the City of Stayton, in Marion County, flowing through floodplain f forests and commercial agricultural fields near Stayton-Jefferson Rd. This project builds on significant existing restoration in the area, including NRCS Wetlands Reserve Program easements on a total of 331 acres, and the Hatch side-channel fish passage, instream, and floodplain restoration (all just downstream), as well as the adjacent, recently purcahsed Chahalpam Wildlife area, a 338 acre conservation easement held by the Grand Ronde Tribe.
In its lower section, Dieckman Slough is lacking instream habitat complexity and areas of floodplain forests have been converted for commercial agriculture. Many resident and migratory fish species (including Threatened Upper Willamette River spring Chinook, winter steelhead and Pacific lamprey) utitlize Dieckman Slough for spawning and rearing. Good quality off-channel habitat is a high priority restoration need in the North Santiam River, as expressed in the draft Willamette/Lower Columbia ESA Salmon and Steelhead Recovery Plan and other planning documents. Recently awarded OWEB grant funds will be used for project management, large wood design and installation along ~3,100 linear feet of Dieckman Slough, as well as floodplain revegetation of 24 acres, coupled with standard CREP.
Project Restoration will begin in the summer of 2015
