Signs like this on private property indicate that the property owner does NOT want people collecting agates on their land. There may be various reasons for this: They want to avoid potential liability, they simply don't want people on their land, they want the agates for their own personal use, or the agates are valuable. Believe it or not, some agates sell for a lot of money.

Eerie Blooms in Lake Erie
August 20 | NASA Earth Observatory
In July 2019, a severe bloom of blue-green algae began spreading across the western half of Lake Erie. The dominant organism - a Microcystis cyanobacteria - produces the toxin microcystin, which can cause liver damage, numbness, dizziness, and vomiting. On July 29, the National Oceanic Atmospheric Administration (NOAA) reported unsafe toxin concentrations in Lake Erie and have since advised people (and their pets) to stay away from areas where scum is forming on the water surface.
