I work at a camp and we have two large ponds (1 and 1.5 million gallons). The 1 million gallon pond has a smaller pond (25,000 gallons) situated above it that overflows with rain run off at times. We're looking to put in a pump to create circulation pulling water from the larger, lower level pond up to the smaller higher elevated pond. What are your thoughts, concerns, suggestions. I'm open to hear what y'all have.
