Summary: Recent research in the Upper Colorado River Basin suggests that despite warming temperatures and reduced snowfall, consistent streamflow declines have not been observed due to increased winter runoff. A study on nine gaged basins of the Salt River and its tributaries found that annual and seasonal streamflow patterns remained stable despite significant temperature increases from 1968-2011, with winter inputs playing a crucial role in streamflow production. Atmospheric rivers were identified as a key contributor to large winter streamflow peaks.

Summary: Accelerated climate change and forest disturbances have significant impacts on water resources in the Colorado River Basin. Our stakeholder engagement and modeling process assesses these impacts, showing that permanent forest disturbances can improve streamflow conditions and reverse declines in supply efficiency under warm/wet climate scenarios, but not under hot/dry conditions.

Summary: The study analyzed global river flow data from 7250 observatories and found that anthropogenic climate change has an impact on river flow. The research showed that some regions are consistently experiencing drying trends, while others are consistently experiencing wetting trends.

Summary: The ongoing drought in the Upper Colorado River Basin has been found to be extremely severe, especially when compared to the tree-ring records from as early as 762 CE. Using gridded drought-atlas data and streamflow data, researchers have developed a streamflow reconstruction model for the Lees Ferry gage, revealing a second-century drought that surpasses the severity of the current drought and documented medieval period droughts. Limited data also support the occurrence of this exceptional second-century drought through analysis of individual tree-ring records and other paleoclimatic data.

Summary: The study used hydrogeochemical and stable isotope analysis to identify the geochemical differences of groundwater in the Walawe river basin, with the dry zone characterized by higher dissolved mineral content and the predominant water type being Ca-HCO3. Isotope data indicated that groundwater recharge mainly comes from northeast monsoon rain, with direct infiltration prominent in wet zones and evaporation-dominated modifications in dry zones.

Summary: Recent intensification of floods and droughts in the Fraser River Basin of British Columbia has had significant impacts that are expected to worsen due to human-induced climate change. The study used tree-ring proxy records to develop subbasin-scale flood and drought season reconstructions, revealing that past high flood-season flows were more severe than recorded, and early 20th-century low flows during the drought season were especially severe. These reconstructions provide long-term benchmarks for natural flood and drought variability prior to human influence, suggesting that current management based on instrumental records may underestimate the full natural magnitude and frequency of extreme seasonal flows in the FRB.

Summary: This study provides estimates of projected baseflow changes in the Upper Colorado River Basin under different climatic conditions, showing potential declines in total baseflow supplied to the Lower Colorado River Basin, with a possible increase under warm/wet conditions. Additionally, the results highlight the impacts of climate-driven changes in high-elevation hydrology on basinwide water availability.

Summary: The overuse of water resources has resulted in significant ecological degradation in many river basins. However, there is a lack of understanding about the relationship between management decisions and socio-economic and ecological outcomes in river basins. This study developed a sociohydrological model to track the evolution of water resources and simulate the response of water resource allocation and regulations to economic and ecological outcomes.

Summary: This study provides direct measurements of evaporation from Standley Lake, revealing its seasonal patterns and the factors influencing it. Summer evaporation is mainly driven by diurnal variations in wind speed and the vapor pressure gradient, while fall and winter are influenced by negative sensible heat transfer. Overall, evaporation plays a significant role in the energy balance of Standley Lake.

Summary: The study found that in the upper Colorado River basin, the annual trend of runoff in March is more statistically significant than in other months. The decrease in cloud optical depth may lead to reduced precipitation and increased temperature in March, resulting in a reduction of available water resources.

Summary: Since 1995, much has been learned about Colorado River hydrology. By analyzing historical flows, tree-ring reconstructions, and climate change, researchers have gained a better understanding of future drought conditions. The study shows that even more severe droughts are possible, based on tree-ring reconstructed flows and future flows projected from climate models. This has significant implications for the management and operation of reservoirs in the Colorado River Basin.

Summary: This study investigates the influence of water management on projected changes in streamflow in the Columbia River basin. The results indicate that regulation reduces shifts in winter and summer flows, but amplifies shifts in warm-season and annual high flows. Additionally, regulation reduces changes in dry-season low flows in headwater tributaries.
