STate space Adult Dam Escapement Model
The primary goal of this project is to estimate total adult escapement of spring/summer Chinook salmon and steelhead that cross Lower Granite dam (LGD). In addition, to meet desired management and research objectives, total escapement has to include estimates of uncertainty and be parsed into weekly strata by three origin groups; wild, hatchery and hatchery no-clip. To reach this goal, we have developed the STate space Adult Dam Escapement Model (STADEM) model that incorporates fish ladder window counts, data from sampled fish at the LGD adult trap, and observations of previously PIT tagged fish at LGD adult detection sites.
This package contains functions to query and summarise the necessary data to fit a STADEM model, as well as write the JAGS model and run it using the jagsUI package in R. Some of the functions can be applied to other dams, and we are actively working to be able to run STADEM at locations other than Lower Granite Dam.
The user can find more information related to installation and use of this package on the package website.
Further details about STADEM can be found in our published paper:

STADEM requires several packages that are available through the
tidyverse package. You can install all the necessary packages by using:
install.packages("tidyverse", "rjags", "jagsUI")
STADEM compendium can be downloaded as a zip from from this URL: https://github.com/BiomarkABS/STADEM/archive/master.zip
Or the user can install the compendium as an R package from GitHub by using Hadley Wickham's
# install and load remotes, if necessary install.packages("devtools") devtools::install_github("BiomarkABS/STADEM", build_vignettes = TRUE)
devtools may require the downloading and installation of Rtools. The latest version of Rtools can be found here.
For the latest development version:
STADEM requires the JAGS software (Just Another Gibbs Sampler). This can be downloaded here:
Please download version >= 4.0.0
Further instructions on how to use STADEM can be found in the package vignette, accessed by typing
