Have you ever played with a hose in the summertime and tried to catch the water coming out of it in your hands? That's kind of like what stream capture is, but on a much bigger scale!
Stream capture is when people change the way a river or stream flows by building a new channel for the water to go through. This allows them to get the water they need for things like drinking, farming, or making electricity.
To do this, they might dig a new ditch or build a dam that forces the water to go a different way. Once the new channel is in place, the water will start flowing through it instead of its original path.
Sometimes, stream capture can have a negative impact on the environment. It can disrupt the natural flow of the river or stream, which can make it harder for fish and other wildlife to survive. So, it's important for people to think carefully before capturing a stream and consider how it might affect the ecosystem around it.
