RHODE-ISLAND RESERVOIR REPORT

Last Updated: March 13, 2026

As the latest observations reveal, the nation's dams and reservoirs are experiencing a variety of storage levels that merit attention from water management officials and hydrologists. Some reservoirs are facing surpluses while others grapple with lower than average water levels, factors that could impact water supply and ecosystem health.

For instance, Lake Winnipesaukee in New Hampshire is currently below its average gage height, which could indicate potential water shortages if such trends continue. Similarly, the Maurice R at Union Lake Dam in New Jersey shows a significant drop in streamflow, hinting at potential drought conditions. On the other hand, reservoirs like Greenwood Lake in New Jersey and Prompton Reservoir in Pennsylvania are slightly above their average water surface elevations, suggesting healthier water reserves.

In the Midwest, the Wanaque Reservoir in New Jersey is notably below its average elevation, raising concerns about water availability in the region. Conversely, General Edgar Jadwin Reservoir and Beltzville Lake, both in Pennsylvania, are experiencing slightly higher than average water levels. This could be a result of recent precipitation events or changes in water management strategies.

Out West, reservoirs such as the John Martin Reservoir in Colorado and Savage River Reservoir in Maryland are above average levels, potentially due to increased snowpack melting or successful conservation efforts. However, the O'Shaughnessy Reservoir in Ohio and Big Chapman Lake in Indiana are registering lower water levels, which may affect local water supply if trends persist.

Reservoir storage fluctuates due to various factors, including seasonal changes, precipitation patterns, and human management. The observed anomalies in water levels across different reservoirs underscore the importance of continuous monitoring and adaptive water management strategies to address the dynamic needs of communities and ecosystems. As such, water researchers and hydrologists are called upon to delve deeper into these patterns to ensure sustainable water resource management in the face of climatic variability and growing demand.

Rhode Island has several major reservoirs, including Scituate Reservoir, Big River Reservoir, and Meshanticut Lake. These reservoirs are fed by various streams, rivers, and creeks, including the Pawtuxet River, Blackstone River, and Moswansicut River. The hydrology of the area is influenced by the nearby mountains, including the Berkshires and the Green Mountains. Snowpack in these mountains can contribute to streamflow and water levels in the reservoirs. In recent years, Rhode Island has experienced both record high and low water levels in its reservoirs. In 2016, Scituate Reservoir reached its highest level in over two decades due to heavy rainfall. However, in 2020, drought conditions led to low water levels in several reservoirs, prompting water restrictions in some areas. Seasonal trends also impact water levels, with typically lower levels in the summer months. Overall, reservoirs and dams provide crucial water resources for Rhode Island and the surrounding areas.
