The cost of building a 10-acre lake is between $1 million and $2 million, depending on how much work needs to be done before construction begins.

Choose an appropriate site for your private lake. It should be at least 1/2-acre in size, with enough elevation to accommodate some water depth so that boats can float in it comfortably.

Determine how deep you want your private lake to be and how much water you want to store there. You can always make it deeper later if needed but it’s harder to remove water from shallow lakes than from deep ones.

Obtain permits from local zoning authorities and county or state environmental agencies before you begin work on your private lake project. These permits will allow you to excavate soil or build retaining walls that could affect drainage patterns or flood control systems in your area. They also help protect natural resources by limiting how much earth is moved during construction of your private lake project

Other factors that affect the cost include whether you’re planning on building the dam yourself or hiring a contractor, as well as whether you’re building a small pond or something larger like a reservoir or lake.

If you’re looking for a more affordable option, consider building a smaller pond instead of an entire lake. According to HomeAdvisor estimates, installing a small pool with an above-ground liner can cost anywhere from $5,500-$25,000 depending on its size.
