Lake 226

[3] This claim was made by soap and detergent companies, as these products do not biodegrade and can cause buildup of phosphates in water supplies that lead to eutrophication.

[6] Due to this relatively small fetch of Lake 226, wind action is minimized, preventing resuspension of epilimnetic sediments.

[6] To test the effects of fertilization on water quality and algae blooms, Lake 226 was split in half with a curtain.

The N:P ratio in Lake 226 had less nitrogen than required to balance the necessary phosphorus amount for successful algae production, which must have occurred to create a eutrophic water ecosystem.

[7] Prior to the beginning of the eutrophication experiment, lake 226 NE had an average secchi depth of 3.76 in 1971.

[7] During the experiment, when lake 226 NE was experiencing algal bloom production from the phosphorus application, the average secchi depth in 1974 was 1.94.

[7] When only nitrogen and carbon were added to lake 226 in the SE basin, there was no decrease in secchi depth over the experiment.

[7] Since carbon and nitrogen were not increasing the likelihood of algal bloom production, controlling the rate of P in the water was discovered to be the crucial element.
