Ladybower Reservoir spillways, today (dry) and when in flood.
There's something both fascinating and terrifying about a colossal hole in a lake, draining water down far out of sight with an immense roar as it freely cascades over the lip.
And yet, when you see them dry, sitting on the dry lake bed in the shallows just by the dam, suddenly they don't seem so scary.

“🌍 Why is this important?
While reservoirs are widely recognized for mitigating drought impacts, their role in controlling how drought propagates through the hydrological cycle has remained largely unexplored. In this study, [the authors] investigate how reservoir storage influences the transition of drought from meteorological to agricultural to reservoir to streamflow drought across the semi-arid Krishna River Basin, India.
🔍 THIS STUDY ADDRESSES TWO KEY RESEARCH QUESTIONS:
✅ How do drought propagation time (initiation, peak, and termination) change from meteorological to agricultural, reservoir, and streamflow droughts across different timescales and threshold values?
✅ How does reservoir storage influence drought propagation between upstream and downstream reservoirs using the Downstreamness concept?
📌 KEY FINDINGS
🔹 Drought propagation differs substantially across drought types because each component of the hydrological system responds at different rates.
🔹 Reservoirs significantly delay the propagation of drought by buffering water deficits, particularly between agricultural and streamflow drought.
🔹 Mild and moderate upstream reservoir droughts rarely propagate downstream, whereas severe upstream droughts consistently transmit downstream, leading to longer duration, greater severity, and delayed onset.
🔹 The downstreamness analysis reveals dynamic shifts in water storage between upstream and downstream reservoirs throughout drought development and recovery, providing valuable insights for reservoir operation and basin-scale drought management…”

• Drought propagation timeframe: initiation, peak and termination are checked.
• Impact assessment using hydrological connection: upstream to downstream reservoirs.
• Severe upstream droughts propagate downstream with increased duration and severity.
• During drought periods water-storage concentration shifts from downstream to upstream..."

Global Performance of #RemoteSensing Based and Reanalysis-Driven Models to Estimate Open Water Evaporation

“ABSTRACT: Evaporation plays an essential role in the water cycle, influencing local and regional climates while directly impacting water availability in lakes. However, directly measuring evaporation over water bodies remains challenging due to the high costs of installing and maintaining the required in situ instrumentation. Although several remote sensing algorithms have been providing evaporation estimates, the lack of a global validation hinders our understanding of their relative uncertainties and performances across different regions. Here, [they] analyze[d] the performance of a suite of models that leverage satellite data and meteorological reanalysis to estimate evaporation over lakes worldwide. [They] compare[d] three remote sensing-based models, one reanalysis-driven model and one ensemble approach, using in situ observations from 27 lakes representing a diverse range of geographic and climatic regions. [Their] results demonstrate that, overall, the ensemble outperformed any individual model in terms of accuracy, with a RMSE and a bias of 1.3 and 0.3 mm/day, respectively. These findings highlight the benefits of using an ensemble approach to estimate open water evaporation with satellite-based models at the global scale, leveraging the unique strengths of each model. For the individual models, differences in the representation of heat storage changes and advection effects led to lower values of RMSE and bias, depending on the location and depth of the lakes. This study sets the path for future improvement of open water evaporation algorithms globally, while remote sensing techniques are proven satisfactory to monitoring of water loss in lakes globally, an essential step toward effective large-scale water resources management.
PLAIN LANGUAGE SUMMARY: Water loss through evaporation in lakes and reservoirs directly affects water availability, which highlights the need to monitor these losses. However, measuring evaporation in situ is challenging and expensive. An alternative is to estimate evaporation using remote-sensing models and compare these estimates with in-situ data to verify their accuracy. Here, [they] evaluated four models and their ensemble (the models' mean value) using measurements from 27 lakes and reservoirs worldwide. [They] found that the ensemble presented higher accuracy and consistency than any individual model because it benefits from the strengths of each model. This approach can guide future improvements in estimating open-water evaporation, which is essential for large-scale water-resource management…”

#WaterShortage fears as Labour’s first #AIGrowth zone sited close to new #reservoir
First #datacentre site proposed seven miles from #AbingdonReservoir planned for water-stressed #SouthEastEngland
by Helena Horton Environment reporter
Mon 13 Jan 2025"Labour’s first artificial intelligence growth zone will be sited close to the UK’s first new reservoir in 30 years, sparking fears that the AI push will add to the 'severe pressure' on water supplies in the area.
"Keir Starmer announced on Monday that he would hugely increase artificial intelligence capacity and reduce planning restrictions on companies that wanted to build datacentres by setting up '#GrowthZones' with fewer constraints [like #ExportProcessingZones and #FreeTradeZones].
"The first of these will be in #CulhamOxfordshire, only seven miles from a reservoir planned by #ThamesWater in Abingdon, which was supposed to provide water to people in the severely water-stressed south-east of England. This is the area of the country most at risk of running out of water, according to the Environment Agency. #Oxfordshire has faced particular issues, with areas reliant on #BottledWater during #heatwaves.
"AI datacentres use a large amount of water, as their servers generate heat. To prevent computer systems overheating and shutting down, the centres use cooling towers and outside air systems, both of which need clean, fresh water. AI consumes between 1.8 and 12 litres of water for each kilowatt hour of energy usage across Microsoft’s global datacentres. One study estimates that global AI could account for up to 6.6bn cubic metres of water use by 2027 – the equivalent of nearly two-thirds of England’s annual consumption.
"Even without a big increase in AI datacentres, by 2050, England faces a shortfall of nearly 5bn litres of water a day between the sustainable supplies available and the expected demand. This is more than a third of the 14bn litres of water currently put into public supply. The south-east faces a potential deficit of more than 2.5bn litres a day in the same period.
"AI could wipe out gains made by businesses in reducing their water consumption; the government is seeking a 9% reduction in non-household (business) consumption by 2037-38 from 2019-20 levels, and currently businesses are on course to achieve a reduction of 6.1%.
Adrian Ramsay MP, Green Party co-leader, said: 'While communities will face #heatwaves, #droughts and water shortages over the coming decades, this strategy locks us into pumping huge amounts of water into AI datacentres. One estimate said AI-related infrastructure may soon consume six times more water than Denmark, a country of 6 million people. What will this mean for residents in water-stressed communities like Culham in Oxfordshire?'"
