Wisconsin DNR Trout Trends2008−2018 Southwest Region
The Department of Natural Resources Fisheries Management staff conduct annualmonitoring of trout populations at 43 locations distributed throughout 17 watershedsin Southwest Wisconsin. These surveys allow for the tracking and evaluation of changesin trout population abundance and size structure through time.
The following data is displayed as the number of trout collected per mile of electrofishing. Each line on the graph represents a different length category, so >8inches indicates all trout above 8 inches that were captured. Each chart alsoincludes typical catch rates for the entire Driftless region (shown as the medianvalue for each length class) for each species. These values are shown to the right ofeach chart, and as dotted horizontal lines. In some cases, the lines may not bevisible within the range of catch rates on the chart. The following slide indicateshow to intepret each chart.
Because a trout's length corresponds to its age early in life, we can also usethis data to estimate year class strength of age 0 and age 1 trout. The differencebetween the all trout value and trout greater than 4 inches value is the amount of age 0trout. The difference between the trout greater than 4 inches and the trout greaterthan 8 inches (7 inches for brook trout) is the amount of age 1 trout. At age 2 the growth slows, and length alone cannot be used to infer age.
Having trend sites spread throughout the watersheds allows us to detect regionaltrends that can help explain variation that may be driven by climate and weather. Stream temperature and stream discharge (flow) are also measured at these locationsto help explain variation and trends.
