DELAWARE RESERVOIR REPORT

Last Updated: December 5, 2025

As the latest hydrological data streams in, a broad overview of the nation's dams and reservoirs presents a complex tapestry of water management challenges and triumphs. Across the board, we see a dynamic interplay between natural water inflows, demand for water resources, and the engineering feats that underpin our reservoir systems. In some regions, reservoirs are brimming thanks to strategic management and favorable weather patterns, while others face the strain of drought, with water levels dipping worryingly low.

Notably, Lake Mead in Nevada is experiencing significantly reduced storage, a reflection of the prolonged drought gripping the Southwest. Conversely, reservoirs like Lake Almanor in California are reporting above-average storage, indicative of recent beneficial precipitations. Moreover, facilities such as the Dillon and Granby reservoirs in Colorado show decreased storage levels, which may affect water availability for local communities and ecosystems. In stark contrast, the John Martin Reservoir in Colorado has seen a dramatic drop in storage, underscoring the need for meticulous water resource planning. Similarly, Elephant Butte Reservoir in New Mexico reveals a stark decrease in storage, highlighting the ongoing challenges in water-scarce regions.

In conclusion, the current state of our dams and reservoirs is a delicate balance, with some enjoying surplus and others facing shortages. As such, the importance of sustainable water management practices and infrastructure adaptation in the face of climate variability has never been more apparent. The data underscores the need for continued vigilance and innovation in preserving our precious water resources for future generations.

Delaware only has a few small reservoirs and dams, with the largest being the Hoopes Reservoir, which provides drinking water to the city of Wilmington. Other small reservoirs include the Killens Pond and Lums Pond. These reservoirs are fed by streams and creeks such as the Red Clay Creek and White Clay Creek. Snowpack and mountainous areas are not relevant in Delaware's hydrology, as the state is relatively flat. The region experiences a humid subtropical climate with hot summers and mild winters. There have been occasional drought conditions, such as in 2016 when Delaware experienced a moderate drought. Overall, the state's water supply is considered sufficient and reliably meets the needs of the population.
