Yes. But generally inadvertently, or by accident.
There is another class of causation - the willfully ignorant who refuse to accept responsibility for their actions.
An excess of phosphate or nitrogen may cause an algal bloom - an overproduction of algae. This algal mat will block light from the water body, and when it eventually dies, it will create an anoxic mat on the lake floor.

What problems can algal bloom cause in a lake?
Oxygen Depletion, resulting in a severe drop in some fish species and general unpleasantness
Can you summarize the role of algal blooms in disrupting the equilibrium in an aquatic ecosystem?
An algal bloom or marine bloom or water bloom is a rapid increase in the population of algae in an aquatic system. Algal blooms may occur in freshwater as well as marine environments. Typically only one or a few phytoplankton species are involved and some blooms may be recognized by discoloration of the water resulting from the high density of pigmented cells. Although there is no officially recognized threshold level, algae can be considered to be blooming at concentrations of hundreds to thousands of cells per milliliter, depending on the causative species. Algal bloom concentrations may reach millions of cells per milliliter. Colors observed are green, yellowish-brown, or red. Bright green blooms may also occur. These are a result of blue-green algae, which are actually bacteria (cyanobacteria). Some algal blooms are the result of an excess of nutrients (particularly phosphorus and nitrogen) into waters and higher concentrations of these nutrients in water cause increased growth of algae and green plants. As more algae and plants grow, others die. This dead organic matter becomes food for bacteria that decompose it. With more food available, the bacteria increase in number and use up the dissolved oxygen in the water. When the dissolved oxygen content decreases, many fish and aquatic insects cannot survive. This results in a dead area.
How does pollution affect organisms in an ecosystem?
Lakes and ponds can go threw the process of succession more rapidly in two ways. First from an increase in runoff wich carries sediments like mud and sand into the pond or lake. Over time this added sediment will cause the lake to fill in becomming shalower and shalower until there is no longer a lake but a bog and eventually a field. The second way is from added nutrients like nitrate and phosphate polutants that will increase the growth of algae which will add to the detritus that sinks to the bottom of the pond or lake when it dies. This will also help to fill in the lake as described above. Algae and sediments also lower the amout of light that can reach submerged plants and can clog the gills of aquatic invertebrates.
Which lake have a higher elevation or a lower elevation to dissolved mineral?
Higher elevation is going to also have higher atmospheric pressure. My recollection is that the higher pressure of the atmosphere on the surface of the lake will cause a higher level of absorption in the lake itself.
What is the major issue concerning the well-being of the Mono Lake ecosystem?
The major issue concerning the well-being of the Mono Lake ecosystem is that some humans are draining the lake for the water. This is a big problem. If the humans stop taking the water there is not enough water for them. But if they keep on taking the water there will be not water left to substance the Mono Lake Ecosystem. But human beings have not found out how much that the lake need to substance an ecosystem.
What can happen after a lake receives a large amount of limiting nutrients?
an algal bloom.
Phosphates and nitrates entering a lake can cause an explosive growth of algae called?
An "algal bloom".
What human activity might cause an algal bloom in the lake?
rivers and run- off from farmers fields bring extra nutrients into a lake allow increased growth of algae in the water. The result is a population explosion of algae called an algal bloom
What problems can algal bloom cause in a lake?
Oxygen Depletion, resulting in a severe drop in some fish species and general unpleasantness
What events typically contribute to an algal bloom in a lake or an ocean?
A decrease in the populations of the things that eat the thingies.
How could an algae bloom cause problem to the lake ecosystem?
it kills animals in the water.
How can algal blooms be harmful to aquatic life?
because euglenophytes absorb waste and such... they recycle it and so!.. when theres to much waste the euglenophytes make things called "algal blooms" the algal blooms deplete the waters nutruents and oxygen killing algae and other organisms
What is Lake color?
Lake color can tell you many things about the water body, like nutrient load, algal growth, and water quality
Why is eutrophication bad?
Natural eutrophication isn't as much of a problem as artificial eutrophication. Artificial eutrophication is caused by humans (fertilizer from farms, lawns, gardens, etc. pesticides, herbicides, road chemicals, etc) these chemicals cause eutrophication to happen much faster than it should. If eutrophication happens faster, algal blooms (large floating mats of algae) form. When algal blooms decay, the bacteria that decays it depletes the oxygen in the lake or pond and the fish die of suffocation.
What can happen after a lake receives a large input of a limiting nutrient?
a "bloom" happens

What are nutrients that build up in a lake over time causing an increase in algal growth?
I'm pretty sure it's eutrophication
