Groundwater Level for Dummies

Groundwater level refers to the depth at which water is found below the surface of the Earth in the ground. You know, sometimes when we dig a hole at the beach and it fills up with water, that's also groundwater, but it's just very close to the surface. When we talk about groundwater level, we're usually talking about the depth of water that is within the soil or rocks beneath our feet.

Think of the ground like a big sponge. When it rains or when snow melts, the water soaks into the ground and starts to fill up this sponge. If you squeeze a sponge, the water comes out, right? Well, it's similar with the ground. When it rains a lot, the groundwater level starts to rise because the water is filling up all the tiny spaces between the soil or rocks. On the other hand, when there hasn't been much rain for a while, the groundwater level goes down because the ground is absorbing more water and there's less left underground.

Groundwater is really important because it's one of our sources of drinking water and it also helps keep our lakes, rivers, and wetlands from drying out. Farmers also depend on groundwater to grow their crops. So, understanding the groundwater level is like knowing how much water is in our underground storage tank. By keeping an eye on it, we can make sure we have enough water for everyone and everything that needs it.

It's kind of like when you have your own piggy bank and you know how much money you have inside. When you check the level of water underground, you can see if it's getting too low, and that's a sign that we need to be careful with how much water we use. Or if it's really high, with water near the ground surface, we might need to be careful about flooding.

So, the groundwater level is all about how deep the water is below the surface, and it tells us a lot about the water supply in an area. It's like a big underground storage tank that holds water and helps us understand how much water is available for us to use.
