Scientific Question: What is the effect of major flooding events on adult and juvenile trout populations in Mack Creek?

The population decreases.

Explanation:

Flood has a very adverse effect on the population of both adult and juvenile trout that lives in the streams because the trouts which has less than one year age are not good swimmers so they can't with stand with the fast flow of water during flood condition so the population of both adult and juvenile trout decreases in that stream in which flood occurs.

the answer is: they occur when the sun, moon, and earth are aligned. in spite of their name, these tides occur twice a year in the spring and fall.
