When there is a lack of rain, the water level in a reservoir typically decreases because there is no water to replenish it, here the contradictory sentence would mean that the lack of rain actually increased the water level, which goes against what typically happens.
Context: The level of the water had increased in the reservoir because of the lack of rain.
Hypothesis: The lack of rain had depressed the water level in the reservoir.

Given this context, determine if the hypothesis is true (Yes, no, or unknown)?
