Optimal Speed

1.8 mph

Minimum Speed0.8 mph
Maximum Speed2.2 mph
Estimated Lure Depth12.2 ft
Temperature Adjustment0 mph
How to Use This Calculator
  1. Select the species you are targeting: walleye, salmon, trout, musky, or striped bass.
  2. Choose your lure type — crankbaits need faster speeds for action; live bait works slower.
  3. Enter the current water temperature in °F — cold water below 50°F requires significantly slower presentations.
  4. Read Optimal Speed in mph and set your GPS or speed indicator accordingly.
  5. Use the Min/Max Speed range to experiment if fish are not responding at the optimal speed.
  6. Check Estimated Lure Depth in ft to target the depth zone where fish are holding.

What each input means

Target Species
Each species has preferred trolling speeds. Walleye prefer slow; musky prefer faster presentations.
Lure Type
Crankbaits need faster speeds for action; live bait works best at slow speeds.
Water Temperature
Surface water temperature in Fahrenheit. Fish metabolism and activity change dramatically with temperature.

What each result means

Optimal Speed
The ideal trolling speed for your species, lure, and conditions.
Minimum Speed
Lower bound of the effective speed range.
Maximum Speed
Upper bound of the effective speed range.
Estimated Lure Depth
Approximate running depth of your lure at the recommended speed.
Temperature Adjustment
Speed adjustment applied due to water temperature. Negative means slower.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Target Species = 0, Lure Type = 0, Water Temperature = 62 = 3 input(s) provided
  2. Calculate Optimal Speed
    Optimal Speed
    1.8 = 1.8
  3. Calculate Minimum Speed
    Minimum Speed
    0.8 = 0.8
  4. Calculate Maximum Speed
    Maximum Speed
    2.2 = 2.2
