I am definitely NOT a pond expert! However, I am a geologist and a pond rookie.
Please wait and see if some of the actual experts on the site will chime in before you make a final decision.
Of course, "it depends" will probably be the answer from any expert that was not actually on site during construction of the pond.
I think you may have a chance for snow tonight to start filling your pond. You don't usually hear about that scenario on Pond Boss!
