Quick and Dirty Way to Check Your Property Well Depth

Quick and Dirty Way to Check Your Property Well Depth

In this video, Felicia talks about how to check how deep you would need to drill for installing a well on your property. If you’re wondering how to find groundwater level or how to find water table level by zip code, this video will help you understand how to find all that out.

From the video:

Are you looking to invest in  land and have no idea how deep to drill for a well?

My name is Felicia I’m a land investor and a partner at Compass Land USA. 

We’ve bought and sold hundreds of properties across the US.

If you give me just a few minutes of your time here I’ll show you a quick and dirty way to find out approximately how deep you’re going to need to drill on your land. We are NOT going to look at the cost of a well or how to actually drill in this video. This video is meant to give you an approximate idea of how deep you would need to go to hit the water tables, which you can use when trying to find companies to drill for you.

Ok, so this is a question that we get a lot. Especially from people who live out of state, so someone who lives in California, let’s say, but wants to invest in some Colorado camping land.

And the last thing you want is to build find that perfect Rocky Mountain property, and then feel like you’d have to drill down halfway to China to get water. Wells are really common in Colorado, especially for more rural properties. Actually, about 15% of Colorado residents get their drinking water from a private well.  I’m going to quickly go over what water you’re getting in a well, and then show you the free online tool you can use to check approximate well depth.

So to understand wells and water, we need to start with aquifers. An aquifer is made up of things like rocks, gravel, and sand. They can be shallow, like a few feet below the ground, or extremely deep, like thousands of feet below the ground. Groundwater is the water that exists beneath the earth’s surface in these aquifers.

Aquifers hold a huge amount of groundwater. You drill down into the aquifer to extract groundwater using your well. Another important thing to note is that the quantity of groundwater can actually fluctuate throughout the year. In the spring when snow melts and you get some heavy rains, the levels could rise. In the summer when it’s hot and dry, levels fall.

So, to check the approximate depth you would need to drill down to hit that water supply. The USGS  manages an online database for groundwater levels. It’s free to use, and a great tool because you don’t have to leave your house. This is an awesome option if you’re out of state and are looking for a rough idea.

I know these sites and dashboards can feel really confusing to maneuver, so let’s walk through an example together. So when you get to the site, you select Groundwater at the top here, and the state you’re looking for. You have all the state options there, personally, we’ve used this site for Colorado, Arizona, New Mexico, Nevada, Florida, and I think Texas.

Normally I would search Site Location by County or the lat-long box. If you’re looking for Water table level by zip code, you’re going to want to use the lat long box and pick a point within that zip code. Site Attribute I would select well depth. Make your selections and click Submit.

Select your County, and you can show the sites on a map. Click Submit again.

So now I’m looking at results for Park County. Zoom in on the map and you can click on the red balloons, which indicate the site of an existing well. You can access data for that existing well, you can see the well depth here. You can use the map to move around and find an area close to your property.

You’ll see a lot more wells in rural areas obviously, than in a city. You can use the data of existing wells around your property to get a general idea of how deep you would need to drill your well.

Keep in mind that this data might not be current, so this is an approximation tool only. Your state government probably maintains a database of drillers’ logs that have water levels recorded when a well was drilled, and consultants often have reports that contain water-level data from shallow boreholes. That information might be harder to get, but you can utilize that as well.


Now if you want to be really certain, like 100%, your best bet is to contact a company out near the property that drills wells and can give you more exact numbers. While you’ve got these guys on the phone you can also talk to them about approximate costs based on how deep they would need to drill.

I’ve not personally had a well installed on any of our properties, so if you have done this, leave a comment below and let me know how that went. I’d be curious to hear about your experience and see if I can learn something from it.🙂

A couple of other things you need to know about wells. First, you need a permit. In most cases, the licensed well driller will help you fill out the necessary paperwork with the County or state. And once the form is approved and the well is completed, you’re pretty much done with the paperwork, most permits are good for the life of the well and don’t need to be renewed.

Second, you are likely responsible for getting your well water tested and making sure it’s safe. This might be different depending on where you’re at, but in most cases, it’s the responsibility of the well owner.

It’s important that you test your well water because there could be contaminants in there that will make you sick. You can contact your County or state health department for certified labs that do water testing. The cost will vary depending on the lab and the tests they do.

Ok so there we have it, you know how to do a quick and dirty check for approximate well depth!
