Angling Tips: Help Trout and Salmon Beat the Heat

brown troutThis spring, trout and trout anglers have benefited from abundant rainfall and cool weather conditions that promote the growth and survival of trout and salmon. However, with the forecast for high temperatures this weekend through next week, it is important to remember that trout and salmon are coldwater sportfish that can experience serious physical stress whenever water temperatures climb above 70° Fahrenheit. Heat stressed fish often seek pockets of cold water created by upwelling groundwater, small feeder streams, or water released from deep reservoirs. These refuges allow trout to avoid or recover from potentially fatal levels of heat stress.

You can help by taking the following precautions during your warm weather fishing trips.

  • Avoid catch and release fishing for heat stressed trout. Trout already weakened by heat stress are at risk of death no matter how carefully they are handled.
  • Don’t disturb trout where they have gathered in unusually high numbers. Because these fish are likely to be suffering from heat stress and seeking relief, responsible anglers will not take unfair advantage of their distress.
  • Fish Early. Stream temperatures are at their coolest in the early morning.
  • Go to Plan B! Have an alternate fishing plan ready in case water temperatures are too high at your intended destination. Consider fishing a waterbody that is less prone to heat stress or fishing for a more heat tolerant species like smallmouth bass.

By paying attention to water temperatures and adapting fishing strategies to changing conditions, anglers can help New York State’s trout and salmon beat the heat.

    One of the great things about beaver dams is that the cooler bottom water seeps out from underneath them, rather than the warmer top water flowing over the top. They serve to significantly lower stream temperature, the cooler water containing more dissolved oxygen needed for trout survival.
