Water depth refers to the distance from the surface of a body of water to its bottom. It is an important measurement in various fields, including fishing, boating, and oceanography. Understanding water depth helps determine safe navigation routes and the types of aquatic life that can thrive in different environments. Water depth can vary significantly in different locations, such as rivers, lakes, and oceans. It is typically measured in units like meters or feet. Tools like sonar and depth finders are commonly used to accurately measure water depth, providing valuable data for researchers and recreational users alike.
