What is a Limnograph?

A limnograph is a chart or graph that records water level (stage) variations in a body of water, such as a river or lake, over time. It is commonly used in hydrology to visualize daily, seasonal, or historical changes in water levels, helping researchers and resource managers understand patterns and trends.
