I want to get an estimate on how cold my pond will get.
It is a 1 acre pond in Central Florida USA. It has an average depth of 4 feet. There is not much circulation in the pond. It gets direct sunlight during these cold months.
These are the average temperatures (high + low)/2 in Farenheit.
°F °C November 65 18.3 December 60 15.6 January 57.5 14.2 February 60 15.6 March 65.5 18.6
What is the warmest temperature the water will remain? Its not as simple as looking at the numbers and will take some judgement. The top half of the water will certainly be warmer than the bottom, and the 1 foot shallows near the bank will be even warmer due to the direct sun.
The fish I am considering putting into this pond will have normal feeding behaviors recommended at 68 degrees but I estimate that it will go into conservation mode and not eat at around 60 degrees or possibly die.
Is it likely that the fish will be able to find water at or above 68 degrees during these months (on the bank or near the surface for the greater part of the day?)
I don't have tools to measure the temperature of different parts of the water, and with the large amount of rain we have had lately the temp would be off.
Thank you for any insight.
