Short summary
Short summary
We built the first global dataset that tracks daily water quality for more than five thousand lakes over twenty years. By turning complex satellite images into simple, ready-to-use tables, we make lake conditions easy to explore. Our new quality checks help users spot unusual or uncertain data. This resource opens the door for better research and smarter decisions about how lakes are changing in a warming world.

Lakes store large amounts of heat that could be used to warm nearby buildings, offering a clean alternative to fossil fuels. To explore this, we added a new feature to a widely used lake computer model (GLM) that simulates how taking water out for heating, and returning it afterwards, affects a lake's temperature. Our feature enable scientists and communities energy planners to check how much energy can be drawn while keeping the lake healthy.

We assessed the predictive skill of forecasting tools over the next season for water discharge and lake temperature. Tools were forced with seasonal weather predictions; however, most of the prediction skill originates from legacy effects and not from seasonal weather predictions. Yet, when skills from seasonal weather predictions are present, additional skill comes from interaction effects. Skilful lake seasonal predictions require better weather predictions and realistic antecedent conditions.

Short summary
Organic matter (OM) turnover into dissolved inorganic carbon (DIC) was investigated by means of carbon isotope mass balances in Germany's largest water reservoir. This includes a metalimnetic oxygen minimum (MOM). Autochthonous particulate organic carbon (POC) was the main contributor to DIC, with rates that were highest for the MOM. Generally low turnover rates outline the environmental fragility of this water body in the case that OM loads increase due to storm events or land use changes.

Lakes and reservoirs are warming across the globe. To better understand how lakes are changing and to project their future behavior amidst various sources of uncertainty, simulations with a range of lake models are required. This in turn requires international coordination across different lake modelling teams worldwide. Here we present a protocol for and results from coordinated simulations of climate change impacts on lakes worldwide.

We explore, together with stakeholders, whether seasonal forecasting of water quantity, quality, and ecology can help support water management at five case study sites, primarily in Europe. Reliable forecasting, a season in advance, has huge potential to improve decision-making. However, managers were reluctant to use the forecasts operationally. Key barriers were uncertainty and often poor historic performance. The importance of practical hands-on experience was also highlighted.

Short summary
This study examines temperature changes in Rappbode Reservoir, Germany’s largest drinking-water reservoir, over four decades. By analyzing detailed temperature data and weather records, the research shows how factors like sunlight and air temperature impact water temperature at different depths. It also finds that late-season warming in deep waters is mainly caused by water withdrawals. These findings help improve understanding of lake ecosystems and can guide better water resource management.
