RHODE-ISLAND RESERVOIR REPORT

Last Updated: January 27, 2026

Across the nation, a comprehensive dataset of the latest observations reveals that water storage levels in dams and reservoirs exhibit a tapestry of conditions, ranging from surpluses to concerning droughts. Major water bodies like Lake Powell in Arizona and Lake Mead in Nevada are reporting storage levels significantly below average, showcasing the stark reality of prolonged drought conditions in the Southwest. Conversely, reservoirs such as Lake San Antonio in California and Lake Texoma near Oklahoma have experienced surges in their water storage, reflecting above-average inflows and potentially favorable hydrological conditions.

The fluctuations in reservoir and dam storage levels are intricately linked to a variety of factors, including regional precipitation patterns, snowpack melt rates, and river flows. For instance, the substantial deficit at Lake Powell — currently at about 42% of its average storage — can be tied to reduced Colorado River flows and below-average snowpack in previous seasons. In contrast, northern reservoirs like Lake Almanor in California are experiencing higher-than-usual storage, possibly due to abundant snowfall in the Sierra Nevada Mountains enhancing the spring meltwater influx. These varying conditions across the country not only have significant implications for water availability and management but also highlight the need for adaptive strategies to cope with the challenges posed by climate variability and change.

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.
