Yield per Recruit App

The Yield per Recruit shiny app is a webpage for interactively exploring the effect of various fish population parameters on the schedule, stock-recruitment relationship and yield. The calculations are performed by the ypr R package, which also generates the plots and table.

Tidal Predictions App

The Tide Predictions shiny app is a webpage for visualizing and downloading tide height data. The tide heights are calculated using the rtide R package. Currently, predictions are available for 637 US stations.

Kootenay Lake Fish Movement App

The Kootenay Lake Fish Movement shiny app is a webpage to view detections of acoustically tagged Bull Trout and Rainbow Trout in Kootenay Lake from 2008 to 2014. Figure 1. A screenshot of the Kootenay Lake Fish Movement shiny app.

Columbia Basin Hydrological Database

The Columbia Basin Hydrological Database shiny app is a webpage that allows approved users to request historical BC Hydro discharge, temperature, elevation and stage data for the Columbia Basin. Figure 1.
