Back in the sixties when winters were cold and snowy I served on the city commission. One of my assigned responsibilities was the street department. One winter the crew came to me and suggested a skating rink. I asked where and how.
They suggested taking the road grader and go in a circle in the small ball diamond to a height of 6 to 8 inches and flood it to a depth of 4 inches and add an inch as needed.
This was used for two or three years.
When the weather returned to warmer they reversed the process and had our ball diamond back.
At least one year when we closed the swimming pool we filled it with dirt to within 18 inches of the top and flooded it to a depth of 4 to 6 inches, and provided firewood for small “get warm fires”.
Ah! The good ole days.
