Hello, I am John Winchester, a water resources engineer at
Hydrosphere, a natural resources consulting firm in Boulder.

Of course no discussion on drought would be complete without the
recognition that a "drought" means different things to different
people. For water users with no carry-over storage, the drought to
fear is any year where precipitation is so far below average that
stream flow becomes insufficient to meet demands. The town of
Nederland is in this group, as is direct diversion (and dry-land)

While systems with carry-over storage may be able to go through
the single really dry year, a string of drier-than-average years may
deplete storage to the point where supply is inadequate. The city of
Denver and anyone supplied by a well (with no storage) fall into this

See for more information on this list.
