Thanks for your reply.

The pond is 1/3+ acres and, after it fills, at its deepest about 13 ft. Average depth throughout is ca. 8ft. Waterfalls have such natural beauty and sound. If I could accomplish roughly the same results as an aeration fountain, I think I will go that route.

If the gpm of the pump was comparable to that of an aeration system, I wonder if the results will likewise be similar?
