The risk assessment for this structure is moderate, highlighting the need for proactive risk management measures to address any potential issues that may arise.

As an integral part of the water infrastructure in the area, Hewes No. 1 plays a crucial role in supporting irrigation, fire protection, stock watering, and small fish pond activities. With its location in a region susceptible to climate variability, maintaining and enhancing the resilience of this dam is essential for sustainable water resource management in the face of changing environmental conditions.
