INDIANA RESERVOIR REPORT

Last Updated: February 1, 2026

The latest observations of the nation's dams and reservoirs indicate varied water storage levels, reflecting a complex interplay of natural and managed water systems. Some reservoirs are experiencing surpluses, while others grapple with the effects of prolonged drought conditions. For instance, Lake Winnipesaukee at Weirs Beach, New Hampshire, is currently below its average gauge height, which could point to decreased inflows or increased water usage. Notably, major water bodies such as Lake Powell in Arizona report storage levels significantly under historical averages, hinting at the broader impacts of long-term drought exacerbated by climate change.

A contrasting scenario is observed at reservoirs like Pueblo Reservoir in Colorado, where storage levels surpass the average, potentially due to recent precipitation events or strategic water management. The variation in reservoir conditions underscores the importance of dynamic water management strategies to adapt to the environmental challenges and ensure sustainable water supplies. Hydrologists and water managers are thus continually monitoring these critical water sources to manage resources effectively, balancing ecological needs with human consumption and maintaining the overall health of watersheds.

Indiana has several major reservoirs and dams used for flood control, water supply, and recreation. Some of the notable reservoirs include the Brookville Lake, Cecil M. Harden Lake, Patoka Lake, and Monroe Lake. These reservoirs rely on streamflow from nearby rivers and creeks such as the White River and its tributaries, the Patoka River, and the Salt Creek. The state's terrain is relatively flat, and there are no significant mountains or snowpack that contribute to the hydrology of the area. Record levels and drought conditions are relatively rare in Indiana, although occasional droughts have affected some regions. The state typically experiences a humid continental climate with warm summers and cold winters, and seasonal trends in precipitation can affect the water levels in reservoirs. Overall, Indiana's reservoirs and dams play a crucial role in managing the state's water resources, providing essential water supply and recreational opportunities while mitigating flood risk.
