White Crappie
Invasive SpeciesFound in 1 lakes
White Crappie is documented in 1 lakes across our dataset — 1 in North Dakota. Each state's natural-resources agency maintains an official "infested waters" roster that triggers boat-launch decontamination protocols. 1 lakes — narrow enough that aggressive containment is still on the table. Most upper-Midwest invasives that established here did so quietly over a decade before anyone noticed, so a low number today is not a guarantee for tomorrow.
The presence of White Crappie does not directly change a lake's LakeGrade rubric score — the grade measures the water itself, not the species inhabiting it. But invasive presence is a meaningful adjacent signal worth reading alongside the grade.
