November: aerators, ice warnings and the year's records

  1. Never assume pond ice is safe; stay off clear ice under 4 inches; aerated ponds have open water.
  2. Penn State says shallow ponds with dense summer plant growth are the most likely to suffer winterkill. Plan next year's plant control with that in mind.
  3. Write down the year: water tests, treatments and permits, stocking and contractor work. Penn State recommends routine testing to document problems and spot changes over time.
