Sunken Cistern in River to Storage Tank, Overflow to Pond

Wondering how to better utilize the existing natural water resources on your property like creeks, streams or rivers? In this example, a cistern (A) is sunk in the creek to control for fluctuations in creek flow and current. The submersible pump is thereby protected from settling on the sediment heavy creek bottom. If the creek depth decreases significantly, the low water sensor protects against run-dry by shutting the pump off. Water moves into a storage tank (B) that overflows into a pond. Solar power (C) runs the pump from sun up until sun down, no batteries needed. Even during cloudy days the pump still operates, albeit at a lower GPM rate.
