Abstract
Same as for Columbia River competition. Again we had no time to think about things in detail, but hope to have time this year to delve into the results a bit.

Description
All code is available at https://github.com/andrew-edwards/sockeyePrize, though is not easily usable by anyone else at the moment and there are various improvements we would make. Most of the covariates were taken from our pacea R package and we used our pbsEDM R package for the calculations. Attached .pdf is our example rendered R Markdown file for Chilko, but might not make much sense to others. Final prediction is given at the very end. Edwards A.M, Rogers L.A., and Holt C.A. (2024).
