“…The majority of lakes and ponds situated in urbanized and highly populated areas tend to receive municipal wastewater discharges, failing septic systems, and sewage overflows, inducing rapid deterioration of water quality and eutrophication (Naselli-Flores 2008). Higher nutrient loads lead to a higher trophic state in urban lakes, as their smaller and shallower morphology (Birch and McCaskie 1999) makes them more sensitive to water pollution and eutrophication. Studies show that high levels of urbanization reduce aquatic biodiversity in urban lakes due to the replacement of natural habitat by roads and buildings (Hassall and Anderson 2015).…”

The ecological impacts of urbanization and eutrophication on zooplankton communities in urban waterbodies have recently gained wide interest. Study findings vary across species and urban waterbodies. How the development of such changes affects the variation of biotic assemblages has only been explored to a limited extent in tropical urban lakes. Spatial and temporal variations of zooplankton community structure in 11 urban waterbodies in the Klang Valley, Malaysia were investigated along trophic and urbanization gradients. Zooplankton and water quality samples were collected three times, between May and November 2017, from two different locations in each lake. All three main zooplankton groups (rotifera, copepoda, and cladocera) were recorded from the study areas throughout the sampling period. The zooplankton community structure, particularly with regard to rotifers and cladocerans, varied between lakes and seasons. Zooplankton diversity does not vary with lake size or distance from the city center but does vary with shoreline development index and urbanization impacts. The zooplankton populations were dominated by rotifers, mainly Brachionus angularis at all study sites during the study period followed by copepods and cladocerans. The total density of zooplankton was significantly highest (p < 0.05) in the hypereutrophic lakes and during the dry season. Zooplankton diversity and rotifer species richness were negatively correlated with total phosphorus (TP). Diversity increased with urbanization and shoreline development, with rotifers as a potential bioindicator of trophic state in urban tropical lakes, due to their close relationship with TP.

“…In the space, which is dominated by asphalt and concrete surfaces, lakes prevent monotony and diversify environment, shape the local microclimate and play an important role in leisure and active recreation of the town's inhabitants (Martinez-Arroyo, Jauregui 2000, Naselli-Flores et al 2007, Tandyrak et al 2015. Stagnating water creates a plane of the composition, which reflects the environment, increases the spaces optically and introduces a variety in the structure of the city (Bartosiewicz 1998).…”

“…Surface flows from urbanized areas bring a number of chemical impurities that among rain water and municipal and industrial sewage contribute to the deterioration of environmental (Kistowski 1996, Birch, McCaskie 1999, Tuszyńska 2006. A common practice in arranging sites on the shores of lakes is a direction of concreted and asphalted paths towards the lake (Lossow 1997).…”

tandyRak R., PaRszuto k., GRochowska J., 2016. Water quality of Lake Ełk as a factor connected with tourism, leisure and recreation on an urban area. Quaestiones Geographicae 35(3), Bogucki Wydawnictwo Naukowe, Poznań, pp. 51-59, 4 figs, 3 tables. abstRact: Lake Ełk as an important element of the urban landscape is associated with tourism and active recreation and because of it with the economy of the town. Since 1999 the renovation method with the use of artificial aeration with simultaneous phosphorus inactivation and also as a biological filter -BIO-HYDRO structures were applied on the lake. This process was lasting 10 years and brought only a short-term improvement. At the same time, the shores of the lake were managed to develop of lake tourism: beach, swimming pool, tennis courts, a promenade, and two a water equipment rentals. The illuminated fountain, the road bridge and well -developed catering -accommodation base were made as well.

“…Urban lakes have a high societal value, providing valuable access to water for local residents. However, increasing human population and urban development have substantially accelerated the eutrophication process in urban waterbodies (Birch & McCaskie, 1999;J. W.

“…Control of algal blooms in urban lakes is a challenge (Birch & McCaskie, 1999;Huser, Futter, Lee, & Perniel, 2016). While reduction of nutrient loading can be partly achieved through watershed point-source permit management based on Total Maximum Daily Loads (TMDLs) according to the Clean Water Act (1972) (National Research Council, 1992), management of nutrient loading from non-point sources (NPS) is usually complex and difficult due to diverse NPS pollution that are transmitted via overland, underground and atmospheric paths and varies according to weather effects (Carpenter et al, 1998).…”

Long-term Variation of Summer Phytoplankton Communities in an Urban Lake in Relation to Lake Management and Climate Conditions

Eutrophication is one of the primary factors causing harmful cyanobacteria blooms in freshwater lakes; climate change such as warmer temperature can potentially further increase both frequency and intensity of blooms. This study investigated the long-term changes in water quality and summer phytoplankton assemblages in Oswego Lake, OR, in relation to lake management practices (e.g., hypolimnetic aeration and alum treatments), as well as climatic and regional meteorological conditions. Both water quality and phytoplankton assemblages were sampled biweekly during summer seasons between 2001 and 2013. The concentrations of total phosphorus (TP), soluble reactive phosphorus (SRP) and total nitrogen (TN) decreased 66%, 93% and 31%, respectively, in response to the hypolimnetic aeration and alum treatments since 2005. The results of summer phytoplankton assemblages showed a 62% reduction of cyanobacteria biovolume and a switch from cyanobacteria dominance (2001-2005) to diatom and chlorophyte dominance (2006-2013). Cluster analysis identified four statistically different groups of summer phytoplankton assemblages (denoted Groups 1-4). Nonmetric multidimensional scaling analysis indicated that the four groups were associated with different water quality conditions. Group 1 occurred prior to hypolimnetic aeration and was primarily comprised of cyanobacteria, associated with water conditions of high nutrients and high primary production. Group 2, dominated by cyanobacteria and chlorophytes, occurred between hypolimnetic aeration and alum surface application. Group 2 was associated with turbid water conditions. Group 3 was dominated by diatoms, occurring after alum surface application. Group 4 included Rstrategist phytoplankton that quickly respond to environmental changes, occurring in the Appendix A: Water quality parameters between 2001 and 2013 in the deep basin of Oswego Lake.
