Landsat satellite estimate, not a field measurement. Lakes without an
estimate are excluded while this filter is set.
Volunteer/agency field measurements: the summer median of the last
ten completed seasons. Lakes without enough samples are excluded
while this filter is set, and bottom-limited medians are lower
bounds — very clear shallow lakes may be missed.
Official DNR adult population estimates. Missing data is unknown, not
evidence that a lake was never surveyed. Estimates are not lake rankings.
DNR's public occurrence inventory is non-exhaustive. “No verified
record” is not evidence of absence. Species-targeted survey results
are not available in a supported public export, so this app does
not claim recent non-detection or label any lake AIS-free.
From the DNR access-site inventory, which is matched to lakes by
name and county. Only lakes with a matched qualifying site are
included while these filters are active. An unmatched lake may
still have access; these filters cannot identify lakes without
access.
