CHaMP is designed as a Columbia River basin-wide habitat status and trends monitoring program built around a single protocol with a programmatic approach to data collection and management (RM&E Workgroup 2010). CHaMP will result in the collection and analysis of systematic habitat status and trends information that will be used to assess basin-wide habitat conditions. When coupled with biological response indicators, this status and trends information will be used to evaluate habitat management strategies. This program will be integrated with ongoing Pacific Northwest Aquatic Monitoring Program (PNAMP) recovery planning efforts and will be part of the collaborative process across Columbia Basin fish management agencies and tribes and other state and federal agencies that are monitoring anadromous salmonids and/or their habitat. The implementation of CHaMP will characterize stream responses to watershed restoration and/or management actions in at least one population within each steelhead and spring Chinook Major Population Group (MPG) which have, or will have, “fish-in” and “fish-out” monitoring (identified in RPA 50.6), thereby meeting the requirements of RPA 56.3, RPA 57, and RPA 3. CHaMP was designed to deliver trends in habitat indicators and requires that monitoring occurs for three cycles of a sampling panel (see section 1.6), at least 9 years.

The South Fork Salmon domain was divided into two major strata (Secesh and Greater South Fork Salmon) for which separate stratification and designs were developed. The standard CHaMP panel structure of an annual and three, three year rotating panels was utilized.  The targeted TRT populations were the Steelhead (Snake River Basin DPS) - Secesh River, Steelhead (Snake River Basin DPS) - South Fork Salmon River, Chinook Salmon (Snake River Spring/Summer-run ESU) - East Fork South Fork Salmon River, Chinook Salmon (Snake River Spring/Summer-run ESU) - Secesh River, and Chinook Salmon (Snake River Spring/Summer-run ESU) - South Fork Salmon River Mainstem.

2012 Design update notes: 

In 2012, there were no changes to the GRTS draw, however the sampling priority shifted to the Secesh and no sites were sampled in the Greater South Fork Salmon strata.

​2011 Original Design Notes:

Secesh site selection design notes: 

For the Secesh, there were 5 legacy sites drawn from the CBW master sample that were previously sampled in 2009-2010 during fish surveys for the Integrated Status and Effectiveness Monitoring Program (ISEMP).  These sites were included as 'legacy' sites included in the pool of sites for the GRTS draw, but were not selectively chosen to be at the top of the Use Order for the draw.  No stratification was imposed for the design, i.e., no allocation of sites by valley class, nor by ownership.  Site allocation to panels followed the standard CHaMP allocation of 15 annual and 10 sites to each rotating panel.

Greater South Fork Salmon site selection design notes:

No legacy sites were used in the design, and 20 sites were allocated in the design within the 4 standard panels (annual and three, three year rotating panels), with 10 sites allocated per panel.

Stratification: 3 valley classes were used as strata, plus the Source strata was split into two, S1 and S2 for Strahler orders 1 and 2 and Strahler order>2.  This was done because of the high proportion of 1-2 Strahler order streams within the frame.  Land ownership (public/private) was not used as a factor in stratification.

Site allocation:

Rho.xy function (from Stevens.strat.panel.4.r) used, by stratum, to order sites.  For the Depositional and Transport strata, the first 12 sites from the ordered list were assigned to the four panels (3 sites to each panel). Oversample sites were then assigned to panels in blocks of four until there were 16 sites in each strata.  For the Source strata, the first 8 sites from the ordered list were assigned to the four panels (2 sites to each panel).  Oversample sites were then assigned to panels until there were 8 sites in each panel.
