What is a subwatershed and
where's the Lower 1?
The Rouge River Watershed is approximately 466 square
miles and includes all or parts of 48 communities and 3 counties.
To manage this large area more effectively, local units of governments
decided to divide the whole Rouge River Watershed into seven subwatersheds
based on the 4 main branches of the Rouge River - the Main branch,
the Upper Branch, the Middle branch, and the Lower branch - and
certain political jurisdictions.

One of these seven subwatersheds is the Lower One Subwatershed.
Check out the map below. Do you live, work, play in, or travel through
any of these areas?

If you do, then your actions impact the Lower One Subwatershed,
or part of the land area that is drained by the Lower branch of
the Rouge River.
The Lower One Subwatershed is approximately 39,785 acres, encompassing
6 communities and 2 counties with a diversity of land use characteristics
that range from almost fully developed to sparsely populated rural
townships. Canton and Plymouth Townships serve as examples of the
more built-out, urbanized landscapes in the subwatershed, with mostly
commercial and residential land uses and fewer acres of natural
features, agricultural and open space land uses remaining. Van Buren
Township, Superior Township, and Salem Township represent communities
that are currently characterized by rural large lot residential
land uses along with agriculture and pasture land. These more rural
townships are experiencing growth pressures from both the west and
the east.
The Lower One Subwatershed is currently one of the most undeveloped
in the Rouge River Watershed. Over 50% of the Subwatershed remains
in agricultural use, forested, or in streams and wetland areas.
Low to medium density residential land use and agriculture/pasture
clearly dominate the developed areas. By observing future land use
trends based on master plans in neighboring subwatersheds, in the
next few decades, residential land uses will dramatically diminish
the areas of forest and open space as well as agriculture or pasture
land. These trends, if not managed appropriately, will have a negative
impact on the water quality, water quantity and wildlife habitat,
as well as the character of the communities in the Lower One Subwatershed.
In general, in the past few decades the communities in the Lower
One Subwatershed have been experiencing tremendous growth rates.
Studies show that the most prevalent land use changes are converting
the landscape from agricultural and open space land use to primarily
residential land uses. A strong economy and the aesthetic appeal
to building new houses in more rural areas has encouraged development
of large lot houses and new subdivisions that pepper the landscape
in various stages of development. In fact, SEMCOG predicts that
the number of households in the Lower One Subwatershed will double
from 1990 to 2025, adding 444 households per year to the Subwatershed.
What's important about the Lower 1 Subwatershed?
The Lower One Subwatershed is especially important to the health
of the whole Rouge River Watershed because it is part of the headwaters
of the River system - or, where the River begins. The protection
of these headwater creeks and streams is crucial to the quality
of water downstream in the Lower 2 and Main 3 and 4 Subwatersheds.
Several high quality creeks drain the headwaters of the Lower One
Subwatershed. In fact, the mottled sculpin - a fish sensitive to
fluctuations in water quality - has been found in Fellows Creek
that runs through Superior and Canton Townships. In some areas of
the Lower One, creeks and the river are supporting more species
of fish than scientists had predicted.
Also, the Lower One Subwatershed is unique within the Rouge River
Watershed because it represents a substantially undeveloped area
with almost 50% of its land still attributed to open space and agricultural
land use. This means that although the urbanized areas of the Lower
One Subwatershed may need cleaning up or restoring, there is a lot
of opportunity to simply protect natural resources - wetlands, woodlands,
open space - that exists in the less developed areas of the Subwatershed.
Protecting these natural resources and open spaces is important
because new residential and commercial development is occurring
at a fast pace.
What are some of the problems in the
Lower 1 Subwatershed?
The good news is that the quality of the surface waters within
the Lower One has been quite good compared to other downstream subwatersheds;
although, increased sediment laden and nutrient rich runoff is becoming
more of a problem as new development occurs. Technical studies on
the Lower One Subwatershed include the 1997 USDA Natural Resources
Conservation District (NRCS) study entitled "Lower 1 Subbasin Resource
Plan, Southeast Michigan River Basin Study" and the draft Lower
One Subwatershed Management Plan currently under development by
the Rouge Program Office (RPO). These plans identify problems within
the Subwatershed as well as the solutions for protecting and restoring
water resources. The following is a list of concerns addressed in
both of these plans:
- High peak discharge rates, flooding
- Increased nutrients
- Sedimentation and erosion
- Loss of natural areas - wetlands, woodlands, the riparian or
streamside corridor
- Need for better recreational opportunities
- Need for public awareness and education
- Need for better data on water quality
- Need for Stormwater Management in planning
How will these problems be fixed?
The six communities and three counties in the Lower One Subwatershed
have been working together for several years to come up with solutions
to the above problems. Their working group, called the Lower One
Subwatershed Advisory Group, or SWAG, is working with the Rouge
Program Office (RPO) and the Michigan Department of Environmental
Quality in developing a Lower One Subwatershed Management Plan.
Based on this plan's guidance, the six communities and two counties
will be developing Storm Water Pollution Prevention Initiatives
(SWPPIs) that will serve as individual "Action Plans" for the next
five years and beyond. These are just a few of the actions that
Lower One Subwatershed communities are taking on as part of their
SWPPIs or Action Plans.
Some actions that have been suggested are the following:
- Adopt natural features ordinance as developed by Salem Township
and Washtenaw County to provide for regulation and enforcement
of natural buffers along wetlands and watercourses.
- Detention pond retrofits to capture smaller storms.
- Develop rain barrel project - education, demonstration, and
distribution - for citizens.
- Wetland restoration.
- Increase nutrient monitoring in headwaters communities.
- Require grassed swales in road right of way.
- Increased street and parking lot sweeping.
- Partnership with businesses through Washtenaw County Community
Partners for Clean Streams (CPCS) program.
- Develop a community or countywide Lawn Care Company certification
program whereby the company can only work in the community if
certified as using certain limited nutrients.
- Develop and adopt local or countywide fertilizer ordinance.
- Implement a residential native landscaping demonstration project.
- Washtenaw County's weekly public radio show, Issues of the Environment,
will continue to air storm water related issues.
- Continue supporting and being involved in local creek citizens
groups such as Canton's CREEC group and the Johnson Creek Protection
Group.
- Regularly educate local boards and commissions about storm water
issues and how they can be aware and help improve our creeks and
the river.
How can I get involved?
If you are interested in helping to protect and restore the Rouge
River in the Lower One Subwatershed, there are many ways to get
involved. See the How to Get Involved
page of this web site for ideas.
