Looks like it's dropped.

That reminds me of the 6-year drought in California, that ended in 1993.
Shasta Dam and Lake in N. Cali. is quite large, though not quite on Powells scale. Once it started raining, water 'experts' were saying that it would take ten years of normal rainfall to refill the resevoir.
It started raining on January 01. By the end of March, the spillways on Shasta Dam were opened and Sacramento, 200 miles downstream, was flooding. 3 months was the fastest refill in the resevoirs history.
