The current condition of the estuary has been catching the eyes of many due to the aquaculture and sand mining activity located nearby. Water quality analysis has been done on the multispectral images from the MicaSense Dual Camera System Payload captured along the estuary and the effects of aquaculture and sand mining activity were analyzed through its turbidity, algae activity and nutrient pollution in the water.
