Pond and Lake Management Tactics According to the Season

Just like any other long term projects that are composed of living organisms, ponds and lakes  require year round management. To make the best use of your time and effort invested into the management of your pond or lake, there are certain times of the year to carry out various tactics to get the best benefits. It's just like your garden - you wouldn’t plant your tomatoes in the fall and expect them to put on fruit mid-Winter. Matching the management tactic to the proper season is crucial.


Winter falls both into the end of a management year and the beginning of a new one, so let's start here. At this point in the season your predator species are primarily dormant and not actively hunting or putting energy resources into growth, which explains why they are harder to catch. In addition to your predator species, the aquatic vegetation in your fishery is dormant and in most cases has died off for the year. This makes the Winter season a perfect time to carry out habitat improvement projects.. The water is typically clearer and with the vegetation gone you can place new habitat structures without them getting in the way. Another great management tactic for this time of year is to make sure your feeders are in proper working order, and the batteries are charged and ready for the growing season. Unfortunately, migrating Cormorants often start showing up this time of year as well and begin predating on your forage populations. Now, these species are federally protected, so beyond non-lethal means of harassing them off your pond or lake, the only other way to protect your fishery is to ensure there is adequate availability of complex habitat to protect your fish. In short, Winter is primarily a time of repair and reflection, with a bit of habitat improvement thrown in.


Spring is the time of the year when your pond comes alive again, and the point of the year where the management is typically the heaviest. At this point in the season you are laying the groundwork for the year to come. Fertilizer applications, vegetation monitoring/ treatment, beginning the seasonal harvest of predators, restarting the feeding regime all of these tasks should be started or carried out at this point in the season.

This is the time of the year that reproduction begins in the fishery. Typically speaking, your Crappie and Bass are the first species to spawn, then followed by Shad and Catfish, and finally your Bluegill spawn throughout the Spring, Summer and Fall. With all of these newly introduced individuals, this is when harvest efforts should begin to help reduce loss to predation and better allocate resources throughout the remainder of the season. Getting ahead of aquatic vegetation at this point in the year helps to gain early control of the situation and reduce input costs for management/control throughout the remainder of the year.. This is also an excellent time to have an Electrofishing survey performed on your fishery to evaluate the population dynamics. This can help to point out key issues that can be corrected early in the growing season before than can compound into greater problems.


Summer turns into more of a maintenance season with key emphasis placed on vegetation control and dissolved oxygen monitoring.  It's at this point in the season that the most damage can occur to your fishery in the shortest amount of time. This is when water temperatures are at their highest, which in turn leads to pond stratification and low dissolved oxygen availability. Because of this, Bass activity slows down, not quite to the extent of the Winter period, but to the same effect focus is put on maintenance instead of growth. These conditions can lead to an exponentially more severe situation if there are large expanses of aquatic vegetation present. During low light conditions, this vegetation utilizes the dissolved oxygen for cellular respiration instead of producing it through photosynthesis. This is why getting ahead of vegetation in the spring season is so important. This is especially true for smaller fisheries less than 3 acres. Larger lakes, greater than 3-5 acres, aren’t as prone to this situation because of the increased surface areas and greater wave action from the wind allowing for greater diffusion of atmospheric oxygen. Important signs to watch for to determine if your pond or lake has a low dissolved oxygen level and at risk for a fish kill is fish “piping” or gulping for air at the surface right at sunup.  Installing emergency aeration equipment such as surface aerators, aerating fountains or bottom based diffusers can help limit your risk for an oxygen depletion at this point in the season.

Fall is typically when fish activity picks back up again. Bass begin to increase consumption to put on more condition/ energy stores to make it through the Winter months. Aquatic vegetation growth begins to slow down as water temperatures begin to cool. It’s at this point in the season that yearly requirements for predator harvests and supplemental stocking need to be finalized to ensure that increased efforts aren’t needed for next year. This is another great time of year to have an Electrofishing survey done. Performing a survey at this time of the year helps to evaluate the recruitment of newly hatched individuals from the previous spring, as well as the growth of your predator/ prey ratio.

As you can see, there is always something that can be done no matter the season.. However, focussing on certain portions of the management plan during the correct season can go a long way in spending less time trying to recover your fishery and more time enjoying it.
