The Naubad karez is the first of the very few known karez systems in India to be documented scientifically and restored. Then, in September 2016, it rained copiously, and the Naubad karez, several irrigation reservoirs and many restored kalyanis have not run dry since. The Naubad karez is likely to have been constructed after his reign was fully established in AD 1427. Reference to a karez system is found in hydrological studies by the Geological Survey of India in Hukkeri near Belagavi. The Karnataka Urban Infrastructure Development Finance Corporation has identified the conservation of the Naubad karez system as one of 17 projects shortlisted for a pilot study.
