Abstract

Reservoirs play a critical role in regulating streamflow and water availability, yet their operations remain poorly represented in large-scale hydrological models due to limited access to long-term in-situ data and the complexity of real-world management practices. C+GDROM, a hybrid empirical–conceptual model for daily reservoir operation simulation, is developed to address these challenges by reducing data requirements while improving compatibility with hydrological models. To support C+GDROM applications, this dataset provides pre-calibrated parameters for implementing the C+GDROM across 1,758 reservoirs in the United States. For each reservoir, the dataset provides the parameters defining the conceptual storage regulation curve, which captures typical seasonal storage dynamics and serves as a key input for C+GDROM. In addition, we provide reservoir capacity features to ensure physically meaningful storage variations. This dataset is derived from the GDROM v2 reservoir dataset, with reservoirs selected based on data availability (≥5 years of records after 1990) and sufficient seasonal storage variability.
