True or False: Heavy, wet snows have a snow-to-water equivalent of 15:10.

The statement that heavy, wet snows have a snow-to-water equivalent of 15:10 is accurate and reflects the general understanding of how snow density relates to water content. In this context, a snow-to-water equivalent ratio of 15:10 means that 15 inches of heavy, wet snow would yield approximately 10 inches of water. This is consistent with the idea that heavy, wet snow contains a significant amount of liquid water due to its density and moisture content.

Understanding this ratio is important for utility arborists, as heavy, wet snow can increase the weight on tree branches and power lines, leading to potential hazards such as broken limbs or downed lines. The ability to recognize the implications of different types of snow on the environment helps in making informed decisions regarding tree maintenance and safety.

On the other hand, lighter, drier snow typically has a much lower water equivalent, which emphasizes the significance of knowing the characteristics of snow conditions when evaluating risks associated with vegetation and infrastructure.
