The Oldószeren River is approximately 100 kilometers long and has a drainage basin area of about 1,200 square kilometers. The river plays a crucial role in the local ecosystem, providing habitat for various aquatic species and supporting agricultural activities in the surrounding areas. It is also an important water source for the region, contributing to the water supply for nearby communities.

The river's course is characterized by its meandering path, which creates a diverse landscape with wetlands, floodplains, and forests. These natural features contribute to the river's ecological significance and provide recreational opportunities for local residents and tourists alike.

The Oldószeren River has been the subject of various studies and conservation efforts due to its ecological importance. Efforts are ongoing to protect and preserve the river's natural habitats and ensure the sustainable use of its water resources.
