Baseflow

Well kiddo, baseflow is like the steady stream of water that flows in a river even when it hasn't rained in a while. You know how when it rains really hard, the water rushes down the river and makes it really big and fast? That's called runoff. But when it stops raining, the river might still have some water in it, right? That's because the water is coming from underground, from places where the soil is wet and the water is slowly seeping into the river. This slow, steady flow is called baseflow. It's like a backup water supply that keeps the river from drying up completely. So even when it hasn't rained in a while, the river can keep flowing because of baseflow. Pretty cool, huh?
