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.

The app uses data from the klexdatr R package.

There are two approaches to visualizing the data:

  1. Movement by Individual
    • Allows the user to view movements of individual fish over time by selecting a fish ID.
    • Detections are aggregated daily for each fish ID; the receiver with the most detections (or in case of a tie, the receiver with the smallest coverage area) in a given day is chosen.
  2. Movement by Group
    • Allows the user to select a group of fish by species and fork length range. For each day, the proportion of detections at each receiver are shown with variable-sized circles.

An appropriate basemap may be selected from the Layer Control button in the top right of the map. We recommend using the ‘Basemap’ layer as it prioritizes visibility of data over geographic features. However, the Satelite (default) and Terrain basemaps may be more useful for orienting oneself geographically.
