NEW-JERSEY RESERVOIR REPORT

Last Updated: December 25, 2025

Amidst the complex network of water bodies that sustain life and agriculture across the United States, the current landscape of reservoirs and dams presents a mixed tapestry of storage levels. As we delve into the latest observations, we witness a panorama of surfeit and deficit, each body of water narrating its own story of plenitude or paucity.

A closer look reveals that significant variances in storage measures exist, some reservoirs brimming over average capacity while others languish below. For instance, Lake Almanor in California is currently holding water volumes well above its historical average, providing a buffer against potential dry spells. Conversely, Elephant Butte Reservoir in New Mexico holds significantly less than its average storage, reflecting concerns of drought and water scarcity. These conditions may be influenced by a variety of factors, including regional precipitation patterns, water management practices, and the resultant impact on local ecosystems and communities.

On the other end of the spectrum, Colorado's Granby Reservoir showcases an uptick in storage, hinting at healthy snowpack contributions or efficient water management. However, the narrative alters starkly in the same state, where Vega Reservoir's storage levels have plummeted, potentially signaling alarm for downstream water needs. Similarly, in Utah, the Willard Bay Reservoir's storage levels have diminished, indicating possible implications for agricultural irrigation and urban water supplies in the region.

This intricate web of water bodies across states is a testament to the variability inherent in hydrological systems and the importance of strategic water management. As researchers and hydrologists monitor these vital resources, the dance between natural forces and human influence continues to shape the fluid story of the nation's dams and reservoirs.

New Jersey has several major reservoirs, including the Manasquan Reservoir, the Round Valley Reservoir, and the Wanaque Reservoir. These reservoirs are fed by a variety of streams and rivers, including the Manasquan River, the Raritan River, and the Wanaque River. The state's location in the northeastern United States means that snowpack and mountain runoff are important factors in the hydrology of the area. Record levels and drought conditions have been observed in New Jersey in recent years, with severe drought conditions experienced in 2020. Seasonal trends show that streamflow and reservoir levels tend to be highest in the spring and lowest in the fall, with the summer months often experiencing drought conditions. Despite these challenges, New Jersey has worked to improve its water infrastructure, including dam and reservoir management, to ensure a reliable supply of clean water for its residents.
