7487Re: Spring runoff and flooding: Big can of Worms!!
- Apr 1, 2008Clay,
you have opened up a chasm,.....
OK- from a scientific point of view-
The answer depends on
a) what crops you're planting, and which vareities
1) are you pushing the envelop with longer season crops, or
b) how much rain you get during the growing season, and how valuable
the run-off contribution is
c) what financial or mechanical means you have to fix the problem
d) what your experience is with this land-how many seasons you've seen
e) how does this tie into a larger perspective with what you're trying
to do with the land
f) what type of soil you have, hydrology, vegetation.. etc
g) how long it will remain flooded for, 15 days during growing season
may constitute a wetland which has certain protection, but that will
depend on f)
from the industrial farmer's perspective (and most soil conservation
drain it, the faster the better
from the environmentalist perspective
let it be, its valuable temporary habitat that feed ground water,
prevents downstream flooding, and can improve water quality.
since you're on this list I would guess you would lean towards the
natural side of things, however, the pragmatist in us all would lead
for a more balanced approach.
Personally, if you have the ability I would really like to see a
small flow-through wetland created, small wetlands can provide habitat
and improve downstream water quality immensely,
however, channelizing the rest to accomplish improved drainage in the
remaining productive areas would be a suitable compromise,... of
course positioning the wetland downstream of the productive land,
the mechanical solution would be to install a larger culvert on the
driveway to drain it faster, however, this could lead to errosion
problems among other things...especially since it the water would be
flowing with minimal vegetation on the land,
you also may need a permit to ditch the land effectively...
