Lake hydrology, water quality and ecology impacts of altered river–lake interactions: advances in research on the middle Yangtze river
Water and mass exchange between rivers and lakes are key processes that maintain the health of the ecology of river–lake systems. Alteration to river–lake interactions have great impacts on water and mass balances. Naturally connected to the middle Yangtze River are the Poyang Lake and Dongting Lake, which are the largest and the second largest freshwater lakes in China. The operation of the ...

Distribution of sterols and the sources of pollution in surface sediments of Ulungur lake, Xinjiang
Domestic sewage discharged into lakes brings great pressure to the ecological environment. This study selected sediment from an inland lake as a research object to evaluate pollution of the environment. Eight sterols were used to evaluate the content of pollutants, while the ratios of sterols were used as the index to analyze the sources of pollution. The correlations were analyzed between ...

Researchers inventory plastics pollution in Great Lakes
A recent inventory of plastics pollution in the Great Lakes will help prevent continued pollution and provide a baseline for those working to clean the lakes, which supply local residents with drinking water. The Great Lakes Basin is a system of five bodies of water and their tributaries along the northernmost tier of the United States, four of which border Canada. They include Lake Superior, ...

Science as a fundamental framework for shaping policy discussions regarding the use of groundwater in the State of Michigan: a case study
The availability and use of freshwater is a growing concern in the United States and around the globe. Despite apparently abundant water resources, several conflicts over water use have emerged in the Great Lakes region and the State of Michigan. These conflicts resulted in state legislation that both addresses water withdrawal from the Great Lakes Basin and requires the State of Michigan to ...

What’s in Your Water
Water can be said to be the essence of life. Indeed, in many indigenous cultures, water is strongly linked to a people’s cultural identity. With the unfortunate news about the amount of lead found in Flint, Michigan’s public water system, perhaps more scrutiny and resources will be designated to improve and monitor this vital resource. But before you pour water into your glass, ...

Understanding the shifts in Lake Erie’s algae toxins
Lake Erie is hiding something beneath its green, murky surface, and it’s more complex than it seems. Recent findings from The Ohio State University throw light on this phenomenon. They reveal that during the early summer, we might be overestimating the harm of these toxins. But as we enjoy the last days of sun, these toxins might get stronger than we anticipate. ...

Progress in Lake Restoration Science
The media almost always gets the story wrong about effective methods to eliminate cyanobacteria blooms in lakes (otherwise known as blue-green algae or harmful algal blooms (HABs). The actual track records for the most talked-about methods are astoundingly poor, about “0 wins” vs “5000 losses” since the U.S. Clean Water Act was passed in 1970. Usually the articles talk ...

Satellite reveals global lakes face a thirsty future
The world’s large lakes, life-sustaining vaults of fresh water, are disappearing at an alarming rate, as disclosed in a groundbreaking study led by Yao et al. This scientific deep-dive unveils an uncomfortable truth: in the last three decades, the volume of more than half of the world’s natural lakes and artificial reservoirs has declined significantly. ...

Case study - Buoy-based temperature profiling in the Bavarian Lakes
In summertime a temperature stratification occurs in deep lakes – the surface water is warm, but deep down the water is cold. This has considerable influence on the nutrient balance and the biological habitat in these lakes. Due to generally higher air temperatures induced by the climate change, both change and have effects on the life conditions of the ecosystems in the lakes. ...

Ultrasound for algal bloom control: background, research and effects
Blooming of (toxic) algae is a global problem that increases each year due to pollution and climate change. In order to restore our aquatic ecosystems, actions must be taken that address excess algal growth. Over the past years, innovations around lake restoration and algal bloom remediation have been introduced and tested. One of these methods is the use of interactive systems that control ...
