Seasonal changes to waterbodies space generally characterized by precipitation and temperature trends during different times of the year. The way we experience seasons varies greatly relying on our location. However, lakes and ponds generally respond in similar ways to the same eco-friendly inputs. Tropical locations experience rainfall patterns comparable to the seasonal transforms that affect lakes and ponds more north.

You are watching: Temperatures in ponds and lakes vary by season.

Summer Seasonal transforms Include Stratification

*
As the weather gets hotter, the thickness difference in between warm surface ar waters and also cold bottom waters rises to a point where two different layers space formed. This phenomenon, called summer stratification, prevents whole lake mixing. Nutrient on bottom that the pond remain there. Also, bacteria consume nutrients and also dead organisms, therefore oxygen depletes faster than that is replaced. Since this oxygen cannot be replaced, this layer loses all oxygen and also becomes anoxic. Anaerobic bacteria digest organic material much slower, bring about the development of hydrogen sulfide gas, which has actually a ‘rotten egg’ smell. This gas usually stays in bottom layer until autumn cooling allows the lake to mix again.

Warm summer water in reality holds much less oxygen. Large algae blooms that conquer the oxygen supply once decomposing after ~ dying turn off is unsightly and can reason summer fish kills. Aerating lakes combats summer problems by avoiding stratification and increasing the in its entirety oxygen it is provided in the lake.

Autumn Turnover

*
Cooler fall temperatures minimize the energy required come mix lakes, permitting complete lake sales to occur. This mixes nutrients and gasses (like smelly hydrogen sulfide) native the bottom layers. Mix of the lake rises oxygen by exposing a greater volume that water to the atmosphere. If a substantial portion of the lake volume lost oxygen in the summer, a rapid autumn turnover occurs. This can reason fish kills by diluting the oxygen that was easily accessible in the surface layer before mixing. Aerating during the summer have the right to prevent this type of fish kill. As autumn temperatures continue to drop, ice formation at the surface gradually reduces mixing.

Seasonal changes in Winter cause Stagnation

*
Cold temperatures slow the metabolisms of all living creatures, to reduce oxygen in winter lakes and also ponds. In lakes covered by ice, water temperature are around 4˚C (39˚F) peak to bottom. The ice cream on optimal is between 0˚C (32˚F) and also 4˚C. Ice is less thick than water, so that floats top top the height of the lake, allowing fish and also other life to stay alive below. Ice can become so thick that tiny light penetrates to the water below. Photosynthesis, currently slowed by the cold, ceases to take ar in the dark. The ice likewise separates the lake water indigenous the environment so the no direct diffusion that oxygen deserve to occur.

Although fish and other organisms need very small oxygen as soon as water temperatures room so cold, oxygen may completely deplete, leading to a winter fish kill. Prevent fish death by maintaining a hole open up in the ice. Include an aeration device to permit the water to proceed to mix and also prevent ice roughly docks and also other frameworks in winter.

Spring Turnover

*
As temperatures increase and melt winter ice, lakes in spring endure warming at the surface that leader to stratification. Entirety lake mixing commonly occurs in spring simply after ice melts. Together the temperatures proceed to climb the distinction in temperature between the surface and also the bottom soon prevents mixing the the 2 layers. Regular spring storms lug not just water to the lake, yet an flow of nutrients from the landscape. Excessive nutrients reason spring algae and zooplankton blooms. This cycle creates even much more nutrients in the lake to it is in cycled up v the food chain.
