Input data set: GRanD reservoirs & dams

Protocol relation: Protocol
Data Type: Other
Simulation rounds: ISIMIP2b, ISIMIP2a, ISIMIP Fast Track

** This data set has been expanded with missing construction/commissioning years, see **

The dam data is based on GRanDv1.1 (Lehner et al., 2011, DOI: 10.1890/100125), but adjusted to match the river-routing in DDM30. After 2010, the data has been provided by Dr. Jida Wang, from Kansas State University (KSU).

Use of these data sets is recommended but, if unfeasible, groups may use their default dataset. For a comparison of this dataset with the default WaterGAP and LPJmL datasets, see

A few of the dams have no information regarding the construction year, and in the varsoc simulations they are assumed to exist during the whole simulation period.
