Upon arrival at a Swift Water emergency, what fact is least important to gather?

When responding to a Swift Water emergency, gathering critical facts can greatly influence the effectiveness of the rescue operation. Among these, the location of the incident is vital for accessing the scene quickly and efficiently. Understanding weather conditions helps in assessing the current risks and potential challenges that may arise due to changing environmental factors. Knowing the number of victims is essential to allocate appropriate resources and personnel for the rescue.

In contrast, the question of the last meal eaten by victims is not relevant in the immediate context of a Swift Water emergency. While this information may have some significance in a medical assessment later on, it does not directly impact the logistics of the rescue effort or the immediate needs of the victims. Thus, this fact is the least important to gather at the scene of the incident, making it the correct answer.
