“…Eutrophication is a major problem globally that has to be addressed by the definition of water quality targets, and establishment of monitoring systems and intelligent watershed management plans (Abell et al, 2020). Although it is critical to prevent water quality deterioration in lake catchment environments (Li et al, 2017c); conflict between environmental protection and economic development makes the task challenging (Mueller et al, 2019).…”

Increasing cases of lake eutrophication globally have raised concerns among stakeholders, and particularly in China. Evaluating the causes of eutrophication in waterways is essential for effective pollution prevention and control. Xiao Xingkai Lake is part of and connected to Xingkai (Khanka) Lake, a boundary lake between China and Russia. In this study, we investigated the spatio-temporal variabilities in water quality (i.e., dissolved oxygen (DO), total nitrogen (TN), total phosphorus (TP), chemical oxygen demand (COD Mn ) and ammonium-nitrogen (NH 4 + -N)) in Xiao Xingkai Lake, from 2012 to 2014, after which a Trophic Level Index was used to evaluate trophic status, in addition to the factors influencing water quality variation in the lake. The DO, TN, TP, COD Mn and NH 4 + -N concentrations were 0.44-15.57, 0.16-5.11, 0.01-0.45, 0.16-48.31, and 0.19-0.78 mg/L, respectively. Compared to the Environmental Quality Standards for surface water (GB 3838−2002) in China, the lake transitioned to an oligotrophic status in 2013 and 2014 from a mesotrophic status in 2012, TN and TP concentrations were the key factors influencing water quality of Xiao Xingkai Lake. Non-parametric test results showed that sampling time and sites had significant effects on water quality. Water quality was worse in summer and in tourism and aquaculture areas, followed by agricultural drainage areas. Furthermore, lake water trophic status fluctuated between medium eutrophic and light eutrophic status from September 2012 to September 2014, and was negatively correlated with water level. Water quality in tourism and aquaculture sites were medium eutrophic, while in agricultural areas were light eutrophic. According to the results, high water-level fluctuations and anthropogenic activities were the key factor driving variability in physicochemical parameters associated with water quality in Xiao Xingkai Lake.

“…Algicides, in particular copper sulfate, hydrogen peroxide, and potassium permanganate, have been widely used to control phytoplankton biomass (Abell et al, 2020). In the present study, increasing phytoplankton mortality proved to be an efficient technique able to reduce 87% of chla concentration on the water surface.…”

“…(ii) phosphorus reduction within the water bodies is mandatory for recovering the trophic state in the reservoirs. Based on the abovementioned recommendations, six scenarios (S1-S6) were simulated to represent classical restoration practices encompassing both external and internal techniques that are usually used to address eutrophication in lakes and reservoirs worldwide (Abell et al, 2020;ILEC, 2005;Jilbert et al, 2020;Lürling et al, 2016;Stroom and Kardinaal, 2016).…”

“…Thus, associated methods are required, such as capping sediments to create a physical barrier between the sediment-water interface (Hamilton et al, 2016) or dredging bed sediments (Cao et al, 2007). Although dredging is costly and it can adversely affect benthic organisms and pose difficulties for disposing dredged sediments, this method is most feasible for reservoirs in high-use urban areas (Abell et al, 2020), as is the case of the BB Reservoir.…”

“…When a water body receives extreme phosphorus inputs for an extended period of time, its recovery may become irreversible, i.e., it cannot be restored by input controls alone (Carpenter et al, 1999). Indeed, the legacy of the internal phosphorus content may be very persistent due to its accumulation and subsequent release, resulting in biogeochemical lags that delay improvements in water quality following the reduction of external PO4 load (Abell et al, 2020). Water quality can therefore remain poor for years, even after external loads have been remarkably reduced.…”

Sustainable management of lakes requires us to overcome ecological, economic, and social challenges. These challenges can be addressed by focusing on achieving ecological improvement within a multifaceted, co‐beneficial context. In‐lake restoration measures may promote more rapid ecosystem responses than is feasible with catchment measures alone, even if multiple interventions are needed. In particular, we identify restoration methods that support the overarching societal target of a circular economy through the use of nutrients, sediments, or biomass that are removed from a lake, in agriculture, as food, or for biogas production. In this emerging field of sustainable restoration techniques, we show examples, discuss benefits and pitfalls, and flag areas for further research and development. Each lake should be assessed individually to ensure that restoration approaches will effectively address lake‐specific problems, do not harm the target lake or downstream ecosystems, are cost‐effective, promote delivery of valuable ecosystem services, minimize conflicts in public interests, and eliminate the necessity for repeated interventions. Achieving optimal, sustainable results from lake restoration relies on multidisciplinary research and close interactions between environmental, social, political, and economic sectors.This article is categorized under: Science of Water > Water Quality Water and Life > Stresses and Pressures on Ecosystems Water and Life > Conservation, Management, and Awareness
