An Overview of the Rouge River
The Watershed
A watershed is the area of land that is drained by a river system
or by a network of river systems. The Rouge
River Watershed includes all of the land area and waterways
which drain into the Rouge River.
The Rouge River Watershed, located in southeast Michigan, runs
through the most densely populated and urbanized land area in the
state. The watershed is approximately 438 square miles in size and
includes all or part of 48 municipalities in three counties, with
a population of over 1.5 million.
Passing through the city of River Rouge, the Rouge River empties
into the Detroit River. The Detroit River is the connecting channel
between Lakes St. Clair and Erie.
Statistics
- More than 50 miles of the Rouge River flows through public parklands,
making the Rouge River one of the most publicly accessible rivers
in the State.
- There are over 400 lakes, impoundments, and ponds in the watershed.
- More than 50% of the watershed is considered urbanized, mostly
in the south and east portions.
- 25% of the land in the watershed in undeveloped.
- The Rouge River itself totals more than 126 miles in length
and is actually four separate branches, the Main, Upper, Middle,
and Lower.
- The Rouge River affects the water quality of the lower 20 miles
of the Detroit River and Lake Erie.
History
The Woodland Indians were the first to settle in the rouge River
Watershed (approximately 1700-1850) followed by the French, the
British and finally by Americans. Because the Rouge supplied them
with food, water, and a mode of transportation, all these early
settlers depended upon the Rouge River for their survival.
The years of 1850-1940 were characterized by immigration, industrial
development, and rapid urban growth. However, it was this development
and growth that led to the first forms of river pollution. To deal
with the increase in population, sewer pipes were built to carry
sewage and storm water which emptied directly to the Rouge River.
Similarly, industrial wastes were poured, buried or dumped in the
most convenient location, which was often adjacent to or in the
river.
Although pollution increased in the 20th century, from 1940 to
the present there has been an effort to protect the quality of life
along the Rouge River. To protect public health and the environment,
the Detroit Wastewater Treatment Plant was built in 1940, and over
50 miles of parkland adjacent to the Rouge River has been acquired
for public use. Numerous federal, state, and local regulations have
been implemented to protect water quality.
Topography
The topography, or surface features of the region, varies throughout
the watershed. The headwaters of the Rouge, primarily in the north
and west areas of the watershed are primarily hilly, while the southeast
is relatively flat. This difference in regions is a result of glacial
activity from the prehistoric period.
Surface
Geology/Soils
The Rouge River Watershed is composed of various materials that
were deposited during the period of glacial activity. These materials
were deposited to form three distinct areas in the watershed: lakebeds,
moraines, and glacial outwash.
Lakebeds are a prominent feature in the watershed, forming a large
part of the relatively flat and level area in Wayne County and in
Southeastern Oakland County. Lakebeds in the Rouge Watershed are
mostly composed of fine sands and clay.
Glacial moraines are a prominent feature in the northwestern part
of the watershed and are characterized by forming the rolling and
hilly topography common to that area. Moraines are a mixture of
clay, sand, gravel, and even large boulders that were deposited
during the glacial periods.
Glacial outwash is found in the northeastern portion of the watershed
and was formed during the glacial melting period. Distinctive beds
of sand and gravel are the main components of glacial outwash.
