True or False: A residential lot can be considered a small watershed.

• A. True
• B. False
• C. Depends on the size
• D. Only if it has a drainage system

Answer: (A)

A residential lot can indeed be considered a small watershed. A watershed is an area of land that collects precipitation and channels it to a common outlet, such as a stream, river, or lake. Even a small residential property can serve this function as it collects rainwater, which then travels across the lot towards specific drainage points. This means that every residential lot plays a role in the local hydrology and water management system.

In understanding this concept, it's important to note that all land surfaces, regardless of size, contribute to the overall water cycle and can affect local drainage patterns. This is particularly relevant in water-efficient landscaping, where managing runoff and maximizing water usage becomes critical, regardless of the scale of the property.

The other options lack the comprehensive understanding of what constitutes a watershed. A specific size requirement is not necessary for the classification, nor does the presence of a drainage system define whether an area can be considered a small watershed.
