I spend $450/mo pumping 24/7 40 GPM 5 HP pump at 170ish feet so I agree it sounds on the light side to me. Entirely depends on the depth of your static water level and size of pump needed.

I recommend contacting NRCS ask them for recommendations on watershed size for 5 ac pond. Talk with local pond owners, they'll provide critical information also regarding watershed size needed for pond size.

Again, multiple ponds are an option I'd encourage you to consider - IMO from a fishery standpoint there's not appreciable difference between fishery potential in a 2 ac pond vs 5 ac - and a 2 ac pond is far cheaper/easier to manage. Multiple ponds open up lots of possibilities.
