Q: Can I run my waterfall and stream in my water garden throughout the Winter? – Carla of Pennsylvania
A: A majority of water garden owners will shut down their water gardens entirely during the Winter, but there are still quite a few that don’t.
Have you ever seen a waterfall with a stream running during the Winter? Its amazing! Ice begins to build up on the falls and you’ll see sections where the water
flows underneath the ice throughout the stream. It really is a beautiful scene.
Having said that, yes you can run the waterfall and stream throughout the Winter, but it depends on these couple factors:
Pump Size (Gallons Per Hour): Here is the major factor in whether or not you can continue to run your waterfall and stream throughout the Winter. Your GPH or gallons per hour must be greater than 2,000 as the water is coming down the waterfall and stream. If this flow is not obtained, then there is a greater possibility the water could freeze, causing ice dams in the stream and pushing the water over and out the side of the stream. If this happened, your water garden would be drained in no time.
Long Streams Beware: Even if you have 2,000 GPH of water coming down the stream, if the stream is quite long, longer than 10′ or 15′, then it may not be a good idea to run the system throughout the winter. In long streams, there is more opportunity for ice dams to be created and thus draining your water garden. If your stream is longer than 10′ to 15′ and you still want to try and run your system I would advise you to use a little bit more flow than 2,000 GPH and to watch it regularly to make sure these ice dams are not created.
I wish you all the opportunity to enjoy your water garden throughout the Winter. Again, it really is an amazing site.
