~ About Faxon Creek
|
|
|
Faxon Creek, which is approximately 3 miles long,
drains wetlands near Tower Ave and 39th Street, as well as wetlands on the
grounds of the Richard Bong Municipal Airport. Ditching to the south
of the airport has diverted nearly 100 acres of surface drainage area away
from the South Superior sewer district to the Faxon Creek watershed. From the airport, Faxon Creek flows
northwest through three campuses, including Northern Lights Elementary,
University of Wisconsin Superior, and Superior High School, as well as
heavily developed residential areas. Faxon Creek is channelized
underground for its last half mile before feeding into Superior Bay near
Barkers Island.
Faxon Creek often floods in Central Park because the
water backs up against the underground channel that begins at the northeast
end of the park. This pipe has a
10-foot diameter and cannot accommodate heavy rain events. To reduce flooding, the City removed 250
feet of the top half of the channel, as well as the swing gate. Bank erosion is apparent along much of
Faxon Creek. In 2006, the City’s
Environmental Services Division received a grant from the Great Lakes
Commission to use the portion of Faxon Creek in Central Park as an erosion control demonstration project. Stay tuned in 2007 to see pictures as
this project unfolds.
Though a number of streams
wind their way through the City of Superior, many of them exist on the
outskirts of town where development is not extensive. Nearly all of
Faxon Creek's length, however, flows through some of the most developed
areas of the city and its riparian area (the vegetated buffer between the
stream and upland areas) has been removed.
This is especially true of the new developments along Tower
Avenue, near the stream’s headwaters, where runoff rates have
increased. Monitoring data (see
below) show that the stream drops most of its sediment load in Central Park
before entering an underground pipe for its final run into the Lake. The water most likely slows down enough
in the park for the sediment to settle out of the water.

Pictures of Faxon Creek

The western tributary of the
Faxon Creek begins upstream of this picture, which was taken from 28th
St. Faxon Creek is pictured here as it exits the culvert under 28th Ave on
its way through UWS. Sampling data is taken from this site, which is
the furthest upstream site of the three sampling sites.

|
The eastern tributary, looking upstream to where it
crosses under 28th St.
|

|
|
|

|
The southeast tributary has
undergone severe erosion from recent development near its banks. The riparian area has been removed,
causing downcutting and bank slumping.
|
|
|
The two tributaries meet near Superior High School,
where this culvert marks the crossing of the creek. Since the lawn is
mowed nearly up to the creek border, there is a good chance that fertilizer
and grass clippings are getting into the water, which can be detrimental to
stream health.

Hill Avenue and into Central Park.
There is more water in the stream as it nears Lake Superior.
|
|
|
Central Park provides a
riparian border, though it is composed of non-native species such as
reed-canary grass, pictured here on the left bank.
|

|
|
|

|
This picture shows more of the
erosion problems facing Faxon Creek.
Diseased trees were removed from the park in winter 2006, and the
branch debris settled in the creek.
|
|
|
On April 11, 2002, Faxon Creek
flooded in Central Park. Flooding like this is often a result of too
much water and not enough space in the storm sewer system. This area of the park was once dammed,
and residents could rent boats to float about on the pond.
|

|
|

|
Central Park is also where
Faxon Creek becomes channelized for its final run into Lake Superior. The small opening serves as a plug,
which causes the water to back up into the park. Our second sampling site is downstream of where the creek
enters this channel.
|
|
|

|
|
The
residents around Faxon Creek love to tell stories about how high the water
can rise!
|
|
When the water recedes, some
of it stays behind in the small floodplain adjacent to the stream.
|

|
|
|

|
Faxon Creek exits its underground channel near Barkers
Island and empties into Superior Bay. This is our last sampling site.
|
|
|
As the creek enters Superior
Bay, the warm stream water melts the ice layer. The light blue stripe in the ice in the background shows
where the ice cutter keeps the shipping lane open. The trees on Minnesota Point are visible
up in the distance.

~ Monitoring Data
|
|
|
|
|
|
Each
set of three data points from the same date are connected by a line for
ease of interpretation. At times,
one or more data points are made smaller than the others when the three
data points overlap. Faxon 3 is the
furthest up stream, Faxon 2 is in Central Park, and Faxon 1 is at the mouth
of the stream.
