- Bodies of water are very sensitive to environmental changes and play an important role in nutrient cycle in their catchment. Due to their natural features such as reduction of the land fill, they may cumulate organic matter from the catchment. Excess supply of nutrients to water bodies contributes to gradual water eutrophication. This process can occur rapidly, particularly in shallow lakes, which are more susceptible to degradation. This also results in deterioration of habitat conditions for many organisms and limits the economic use of water. Eutrophication may lead to gradual shallowing and shrinkage of water bodies, and, consequently, to disappearance of lakes. Thus, proper diagnosis and reduction in the amount of pollutants flowing into lakes are key factors to improve water quality and prevent their further degradation. Lake Głęboczek, like many other urban lakes year were powered by sewage. As a result, the tank has ceased to be an attractive element of urbanized land, and became the object of nuisance for residents, often acting health risks. For this reason, the lake has undergone numerous Głęboczek reclamation treatment and protection. The object of this study was rehabilitated water from the lake Głęboczek in Tuchola. Samples were taken 12-fold in 3 places during the period from March 2011 to February 2012. In the tested water was determined by the colorimetric method phosphorus, phosphate, nitrogen, nitrate, nitrite, and aluminum. Additionally, the pH and temperature. Lake Głęboczek is a reservoir, which is heavily influenced by human activities, direct and indirect. This is due to the central location of the water, the entire drainage area is densely populated and intensively exploited for agricultural purposes. One of the most important elements harboring an increase in trophic status of the lake, is its low average depth. In addition to the lake Głęboczek not affect any river, which prevents water exchange and causes the accumulation of pollutants. Both the results of their own and other authors suggest that the degree of eutrophication of the lake Głęboczek apparently decreased. The level of biogenic elements and their compounds was higher than the results obtained in 2001 (after restoration), which may indicate improper sewage and agricultural economy in the catchment of the lake. Oversize nutrient content indicate a renewed increase in trophic lake.
