Yes there is a 4x~10 spot that stays open year round and i even have some plant growth there during the winter months. It is the same spring i had taped and brought into the house for our water use. I had a tank placed into the ground (500 gallon) then put in an overflow to allow water to overfill the tank and go into the pond when we are not using the water. I ran a water line 3ft below grade and then into the house and we have perfect spring water. I have it tested each year to be sure but it has always came back as good stuff. It flows at over 2.5 gallons a minute year round and it's nevber run dry.
