Submerged Aquatic Vegetation (SAV) Abundance (1984-2025) ^‍‍

In some years, factors such as poor weather, highly turbid water, access restrictions and equipment failure have prevented researchers from collecting aerial imagery. For these unmapped areas, estimates of SAV acreage are based on the prior year’s survey. Data was not collected in 1988. See how these data are used in the Submerged Aquatic Vegetation (SAV) Outcome.
