Did you Google "R stat water resources optimization" or "r stats optimization"? It seems that applying some of the references below with R packages in the optimization task view probably gets you where you want to go. https://cran.r-project.org/web/packages/reservoir/reservoir.pdf https://www.res

The task view lists many R packages for optimization and I would appreciate suggestions from those familiar with the available tools for packages that might be suitable for water management. Limited water resources need to be apportioned among various competing users (e.g,, agriculture, fish and
