The hydrological regime of the Dragor River is characterized by significant seasonal variation, with high flow periods occurring during April and May, moderate flows between November and March, and lowest water levels from July to October.

, adapting the widely-used Tennant–Montana method to the local hydrological conditions. The original Tennant–Montana method calculates environmental flow as a fixed percentage of a river's mean annual flow, divided into two seasonal periods. However, this standard approach was not suitable for Dragor due to significant seasonal variability in water availability. Therefore, researchers modified this method by defining three distinct periods based on Dragor's flow regime: a high-flow period (April–May), a moderate-flow period (November–March, June), and a low-flow period (July–October). Each period received a tailored percentage of the mean flow—10%, 15%, and 30%, respectively—to better reflect and protect the local aquatic habitats throughout the year.

, illustrate the interplay between geography and language. Examples include ("Come on, are you telling me where Dragor flows from?"), implying unnecessary explanation of common knowledge, and ("Are you looking for waste food in Dragor?"), historically reflecting the practices of impoverished locals scavenging discarded produce from the river. Another idiom, ("Dragor brought it, Dragor took it away"), denotes fleeting circumstances, while ("Dragor has taken its tax!") refers to the belief that the river occasionally claims lives as a symbolic tribute following tragic events. These expressions illustrate Dragor's significance in the local cultural and linguistic landscape.
