Dam: A Comprehensive Guide to Its Legal Definition and Significance

Definition & Meaning

A dam is defined as an artificial barrier that can hold back water, wastewater, or other liquid materials. It serves the purpose of storing or controlling water. To qualify as a dam, the structure must meet specific criteria:

  • It must be at least 25 feet tall when measured from the lowest point of the stream channel or watercourse to the maximum water storage level.
  • Alternatively, it can be considered a dam if it has the capacity to hold at least 50 acre-feet of water.

However, certain structures are excluded from this definition, such as levees or smaller barriers that do not pose a significant risk to life or property in case of failure.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A municipality constructs a dam that is 30 feet tall and can store 100 acre-feet of water to manage local water supply and flood control.

Example 2: A small recreational lake is created by a barrier that is 5 feet tall and holds 10 acre-feet of water. This structure would not be classified as a dam under the legal definition.

State-by-state differences

State Definition Variance
California Specific regulations on dam safety and maintenance are more stringent.
Texas Regulations may vary significantly based on local water management practices.
