Hello!
The amount of water in a river varies for each particular area. Whether the area has been receiving rainfall or a drought.
Seasons also play a role; if it's Spring, you may receive more rainfall and have a higher water levels. If it's Summer, you may experience a drought, causing lower water levels.
