Harvesting Glacial
Meltwater with Managed
Aquifer Recharge

his is a somewhat stream-of-consciousness article to get
some exposure for, and feedback on, an idea that
I have been floating for almost a decade. See Campana
(2016 and 2017) for more information.

No glaciers in Glacier National Park?
Really? Where did their water go?
In response to global warming,
some mountain glaciers are melting at
accelerated rates in various regions (see
slides 14-18 in Campana, 2017). This is
not unique to exotic places - we know
that some permanent glaciers in North
America are shrinking and some are en
route to extinction. In the United States,
the best example of this phenomenon

is Glacier National Park in Montana,
which might be glacier-free by the
middle of this century. Here in western
Oregon, where I live, the highest
elevations (e.g., Mt. Hood) are losing
permanent glaciers. In addition, our
seasonal snowpack in the Cascade
Range will likely decline as the climate
warms and more precipitation falls as
rain and not snow (see slides 20 and 21
in Campana, 2017).

Glaciers provide humanity and
ecosystems with 'free storage' of freshwater
and parcel out water to maintain and
replenish freshwater supplies. During the
warm season, glacial meltwater nourishes
lower elevation ecosystems and human
settlements alike. It can recharge aquifers.
Replenishment of the glacier normally
occurs during the cooler seasons; the cycle
then repeats itself. Ideally, one would like
a balance: the glacial ice melting in the
summer would be replaced by cold weather
precipitation. When the melting exceeds
the replenishment, then the equilibrium
is disrupted. The volume of the glacier
shrinks and if the disequilibrium continues,
the glacier will disappear entirely.
My idea is to capture that excess
meltwater - the amount coming
out of storage - before the glacier
disappears altogether.

Recharging glacial meltwater
I first presented this idea at the 2013
AWRA Annual Conference in Portland,
OR (see Session 88 @ http://bit.ly/2tgkFCu].
How did I get this idea? I visited Copiapó,
Chile, in August 2008 during the Chilean
winter. Copiapó is a city of about 160,000
in the southern Atacama Desert, one of
the driest spots in the world. I was told by
some of the locals that there had been no
measurable rain in 20 years; the average
annual precipitation is about 19 mm (0.75
inches). Despite the lack of rainfall, the
Copiapó River was flowing, albeit barely.
