March 6, 2008 - Update
Big rains, and more on the
way. Francis E. Walter at the height of the runoff from
this most recent rain, and the snowmelt event was taking in
upwards of 8,000cfs, if not more, while only releasing 250cfs.
However, even with this minimal release, downstream Walnutport
flood stage which is about 17,500cfs or 8' on the gage. Walter
no doubt minimized the flooding in the Walnutport area, but
it certainly did not stop it. By the way, the two green, and
lone red and orange dots on the map to the left represent
the gages immediately downstream of the four Delaware River
flood control impoundments managed by the Corps' office in
Philadelphia - - north to south - Prompton, Walter, Beltzville
and Blue Marsh.
Out in Central PA Penns Creek
also surged. It exceed
flood stage as well - - and in fact it crested at a level
more than doubled its previous record for the date. Old record
for the date (03.05) was 4,870cfs - recorded back in 1979.
Now what is somewhat of a concern is how our
waterways are going to handle the next moisture-laden system.
As of now, and what definitely seems to be the norm these
days, the exact track for an event 3 days out has yet to be
pinned down. Hopefully, this event will be a white one for
our higher elevation, big-water watersheds since we certainly
don't need a repeat of the April
2005 series of rain, snowmelt, rain events that lead to
flooding along the D. Not to mention, going into this
next system, chances are, all the under-the-microscope Upper
D, NYC drinking water reservoirs will be spilling.
