Notes
very rocky bottom, deep sediment.
We saw female and male mallards - no ducklings though.
Fish species included rock bass, bluntnose shiners, and killifish. There were also a surplus of young-of-year perch and largemouth bass.
Macrophytes seen were flatleaf pondweed, richardsons pondweed, elodea, and white fragrant waterlilies.
