shouldn’t have dived into Philips Lake

Nyah, nyah,
nyah. Told you so, told you so. OK, that’s somewhat childish.
But that was my first reaction when I learned that Philips Lake
(or Bristol Lake, or whatever it is called these days) was recommended
for placement on the state’s "impaired waterbody"
- or 303(d) - list.
This documents
that Philips Lake is officially "waters of the state"
and "waters of the United States." It is not a farm pond,
where all of the waters are contained within one property. Rather
the waters of Philips Lake drain from across Highway 63 and into
Clear Creek - both well beyond the boundaries of the Philips Tract,
now owned by Jose Lindner.
Granted, the
pollutant is mercury and comes from atmospheric deposition. There
are a number of water bodies - mostly ones with a lot of surface
acres - that are polluted by mercury. No one seems to be much inclined
to do anything about this because the sources are many coal-fired
power plants to our west - maybe as far away as China or as close
as Kansas.
So, while there’s
not much planned to deal with the mercury pollution of Philips Lake,
it is clear that the city of Columbia, by accepting Philips Lake,
has also taken on the responsibility of keeping it supportive for
recreation in and on the water and for aquatic life.
The standards
for the first category - recreation in and on the water - are primarily
the level of germs, and those standards are likely to be met. The
presence of high levels of germs stems mostly from sewage, and,
as far as is known, there’s no sewage runoff into Philips
Lake. But, regardless of statements from the city of Columbia that
swimming will not be promoted, the waters of Philips Lake must meet
the standards for recreation in and on the water. The only possibility
for escaping those standards is to show that no one has engaged
in swimming or boating since 1975 - a high hurdle, indeed. Again,
however, there is little likelihood germs will contaminate Philips
Lake.
The second category
- aquatic life - is more problematic. Aquatic life - fish, waterborne
insect larvae, crustaceans (such as crayfish) - don’t do very
well in sediment. Sediment runoff, otherwise known as mud and all
the nasty things it contains, is quite likely as construction moves
forward at the Philips Tract. The city of Columbia is now responsible
for ensuring that the waters of Philips Lake are not impaired by
that runoff.
The developer
has constructed berms around the lake to prevent runoff from construction
from entering it. But storm-water prevention measures fail. Water
overtops berms. Berms collapse. Akin to those plastic fences, berms
do real well in dry weather but don’t fare so well in heavy
rains. This area has experienced lots of rainy weather this summer,
and neither plastic or straw fences nor earthen berms are designed
to handle the downpours we have experienced lately.
What happens
when berms are overtopped or fail? Sediment - mud containing construction
debris - goes downhill. Downhill in this instance is Philips Lake.
Like it or not, by accepting Philips Lake as part of the parks system,
the city of Columbia also accepted the liability for construction
runoff.
As was pointed
out, the city went for a pig in a poke and lost.
