As a responsible pond owner, you have done your homework. You’ve winterized your backyard – shut down the pond water features, stopped feeding the fish, and invested in a good aerator. You are to be commended; winter pond maintenance can be a difficult job, but it will keep your pond healthy through the coldest months. But don’t forget that the reason you have a backyard pond is to enjoy it! Don’t winterize your pond and forget about it; enjoy it this winter!

Winter is a wonderful time of year that provides beautiful snowscapes. Often times, people are unsure about what to do with their waterfalls in more frigid temperatures. Here are a few things to consider to help you to determine if your waterfall should be run on your water feature during winter. Read more Should I Run My Waterfall in Winter?
If you have a fish in your pond, moving into the winter season can be a concern. You want to make sure you are taking the best care of your fish through this season. Luckily taking care of your fish during this time can be simpler than you may think. Read more How to Care for Pond Fish in Winter
As winter temperatures are beginning, it is time to start preparing your pond for winter. The first thing to determine is what water temperatures you are anticipating in your area. If you anticipate your pond to freeze solid or just the surface of your pond to freeze, your steps will be different. Read more How to Close Your Pond for Winter
As cooler temperatures arrive, it is time to begin thinking about how to prepare for closing your pond for winter. Depending on the region you live in and the temperatures you anticipate can alter the preparations you need to make before winter. This information will focus on those areas which anticipate freezing temperatures, so if you do not anticipate this kind of weather, you can adjust your preparation needs. Closing your pond is the process of winterizing your pond by preparing your pond pump, fish, and plants. Read more Prepping for Closing Your Pond
It is true that offseason lake management equals summer enjoyment. And, there are a fair number of items that occur in the winter that can cause issues as the weather warms up.
Adverse Conditions that Effect Lake Enjoyment
Algae, aquatic weeds, fish kills, and odors are naturally occurring conditions that can adversely affect the enjoyment of a lake and they are all caused by the same winter contaminations: namely, decaying trees and plant material, “deposits” from migratory waterfowl, and a severe depletion of oxygen.
How to Prepare A Lake for Winter … And Limit Winter Contamination
There are a number of methods that lake managers employ during the winter months to limit adverse conditions during the warmer months. Some of these are:
- Aerating the lake, yes, even during the winter months. A common misconception among many lake owners is that aeration for pond isn’t needed during the winter months. Yet, running a sub-surface aeration system year around provides many ecological benefits including the addition of dissolved oxygen required by fish (thus, preventing fish kills) and helping to cycle nutrients throughout the water. Additionally, increased oxygen levels help limit algae and harmful bacteria from flourishing.
- Mechanically removing excessive plant material by raking, cutting, or uprooting. This is usually only undertaken when there is an imbalance in the plant populations and a plant species is impeding the desired use and aesthetic of the lake. Before initiating any such plan to mechanically remove plants from your lake, reach out to your local watershed authority to determine if a permit is required. Also, many lake management plans follow a “let nature be natural” philosophy. For more information on the pros and cons of leaving plant material to decay in a lake, go here.
- Employing wintertime drawdown. This is where the water levels of the lake are dropped significantly. It exposes the sediments and aquatic plants to freezing temperatures, greatly limiting their populations in the coming year. It goes without saying that there can be some serious ecological issues for the lake with this method, as it affects all plant and wildlife in the shallower areas of the lake. Determine if this solution meets your needs for surrounding properties and docks, and for the plant and wildlife in and around your lake.
- Employing winter-time waterfowl prevention techniques. Migratory birds, such as Canadian geese, can cause water toxicity issues as their droppings decompose and set the stage for early oxygen depletion the following year. Techniques to manage birds depend on lake size, type of bird, proximity of human habitation, and feeding areas and may require federal permits before initiating. Options may include the construction of fences, walls or buffer strips of shrubs along lake shorelines to prohibit easy movement in and out of the water for the birds, just to name a few.
