“…However, because sewer lakes were less eutrophic than septic lakes, these results suggest that lakes do recover to some extent from previous nutrient pollution. However all developed lakes had reduced water quality conditions as compared to the undeveloped lakes in our study, thus suggesting that recovery is not complete (Figs 4,5).…”

“…Lakes in urban centers may be more eutrophic because they have higher densities of humans and associated human impacts (4,5,14). If so, then we would predict that lake eutrophication would be correlated with shoreline residential development.…”

“…Population growth, and specifically residential development, is associated with many environmental impacts (3), including nutrient pollution and subsequent eutrophication of lakes (4)(5)(6). Eutrophication of lakes refers to a group of symptoms that lakes generally display when they have been overloaded by nutrients, namely nitrogen and phosphorus (7,8).…”

Nutrient pollution and associated eutrophication of freshwaters threaten the ecological integrity and the services provided to humans by lakes. We examined how human residential development influenced the level of lake eutrophication in the Seattle, WA, USA, region. We surveyed 30 lakes and measured 3 indicators of eutrophication: concentrations of chlorophyll-a and phosphorus, and the proportion of algae that are inedible to zooplankton. We classified lakes based on the waste-treatment method for shoreline homes: septic, sewer, and undeveloped lakes. Septic lakes occurred along the urban-rural fringe while sewer lakes occurred near urban centers. Septic lakes were more eutrophic than sewer lakes and undeveloped lakes, as indicated by higher levels of phosphorus and chlorophyll-a. These results suggest that septic systems contribute to the high levels of eutrophication in lakes at the urban-rural fringe. Lakes at the urban-rural fringe represent an opportunity for proactive management of urban expansion to minimize lake eutrophication.

“…[2][3][4][5] In general, nutrient concentration and composition in reservoirs are largely determined by watershed nutrient inputs and within-channel transformation 6 and are typically regulated by seasonal runoff changes and hydrological conditions. 7,8 A few studies speculate that phytoplankton communities and biomass change seasonally, which is associated with river discharge, hydrologic regime, irradiance, water temperature, and nutrient concentrations and ratios. [9][10][11] Understanding seasonal and hydrological inuences on nutrient and phytoplankton is essential to develop nutrient management strategies to mitigate eutrophication.…”

Small river reservoirs are widespread and can be ecologically sensitive across the dry-wet transition under monsoon climate with respect to nutrient loading and phenology. Monthly sampling and high-frequency in situ measurements were conducted for a river reservoir (southeast China) in 2013-2014 to examine the seasonal pattern of nutrients and phytoplankton. We found that nutrient concentrations were runoff-mediated and determined by watershed inputs and, in some cases, by internal cycling depending on hydrology and temperature. Ammonium and phosphate were relatively enriched in February-March (a transitional period from dry/cold to wet/hot climate), which can be ascribed to initial flushing runoff from human/animal waste and spring fertilizer use. A phytoplankton bloom (mainly Chlorophyta) occurred during April after a surge of water temperature, probably due to the higher availability of inorganic nutrients and sunlight and suitable hydraulic residence time (medium flow) in the transitional period. The concentration of phytoplankton was low during May-June (wet-hot climate) when the concentrations of total suspended matter (TSM) were highest, likely owing to the "shading" effect of TSM and turbulence of high flow conditions. Nutrient-algae shifts across the dry-wet season and vertical profiles suggested that algal blooms seem to be fueled primarily by phosphate and ammonium rather than nitrate. Current findings of a strong temporal pattern and the relationship between physical parameters, nutrient and biota would improve our understanding of drivers of change in water quality and ecosystem functions with dam construction.

Nutrient removal and storage take place in various components of the river basin controlled by physical, chemical, and biological processes (e.g.…”

Six small dam reservoirs in northeastern Poland, with different hydrologic and catchment characteristics were selected for research from March to October (2001October ( -2003. There was a significant correlation between DOC and TP in the reservoirs and the water retention time (WRT). The highest values of electrical conductivity (EC) were recorded in reservoirs with an agricultural basin. In almost all reservoirs a statistically significant decrease of EC, compared to inflowing waters, was noted. Nitrates were substantially reduced in afforested catchment reservoirs. The highest TP concentration was recorded in a newly flooded reservoir. In reservoirs with long retention time, phosphorus sedimentation takes place more intensively. This caused phosphorus reduction in outflowing waters.
