a) reversal of stream flow direction
b) new lakes to form
c) slow groundwater flow
d) fast groundwater flow
I think it’s either a or d ; instructions are to choose the most correct. I know for a fact that overpuming lowers the water table and changes the direction of the groundwater but I’m not sure which direction; which is why I am leaning towards a. Any insight greatly appeciated!

the question is extremely poorly stated. gravity controls the direction that streams take, water always flows downhill, period. but assuming that there is a deeper meaning to the question, i would say the answer is a) but that takes some explaining as to why. by “direction” i take that to be a awkward means of saying that a stream is either influent or effluent in its relation to the surrounding groundwater. many small streams are effluent, that is the surrounding groundwater contributes water to the surface stream flow. a condition sometimes called “natural springs”. if the water table was lowered, by pumping for instance, the stream might start losing water to recharge the groundwater. that is an influent stream. many states regulate wells that are placed close to streams as if they were an “alternate point of diversion” of stream water, and can only be pumped if the owner has surface water rights.
a) reversal of stream flow direction is best
