This person is fishing in a small, freshwater body of water. This body of water flows into a larger body of water called a river. What is this small body of freshwater called?​

Explanation:

The smallest body of water is the brook, a natural stream of water that is found aboveground and is often called a creek as well. A brook is usually a tributary (a small body of water that naturally flows into a large one) of a river, but this is not always the case.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
