Main pond is stocked and 3 feet from full pool.
There is an area appx. 60 x 60 east of the pond that is collecting water after any rain event over .25 inches. Probably a foot of water and takes a few weeks to evaporate off. I figure, let's make lemonade from lemons and make a mini forage pond. There is a 1 foot berm appx. 20 feet wide separating the main pond from the possible forage pond site when the main pond is at full pool. I plan on stocking the same forage in the mini pond that is in the main pond. Supplemental forage only, not experimental.
Here is my dilemma, If I build the mini pond from the current dirt level down I risk the mini pond being overtaken by the main pond when the main pond is 12 inches over full pool. However, during normal rain events the mini pond will be fed by appx. 2 acres of clean runoff. My other option is to build a 2-3 foot berm around the forage pond which will keep it separate from the main pond but will eliminate any runoff from filling the mini pond. I do have a 3 inch trash pump which could be used to fill the mini from the main periodically.
I appreciate any advice from you all.
