Shakebaker,

Losing 5 to 6 feet of depth may have substantially reduced the surface area of your pond. If so then the LBS/Acre of fish would be higher than what is normally carried. Should this happen again, you may consider removing LMB and BG in proportion to the loss of surface water. This may prevent a kill.

Should it happen again, you might also consider broadcasting a combination legume/grass mix across the exposed pond bottom. If it hatches and the pond fills slowly until late winter rain events there is potential for a big boost in fertility for the remaining population the next year.
