Upper Silver Creek Watershed Plan
Welcome!Thank you for coming this evening to the Open House for the Upper Silver Creek Watershed Plan.
Tonight you will have the opportunity to learn more about the Upper Silver Creek Watershed Plan and provide input that will be used to help develop the plan.
Elements of the Watershed Plan: Document Existing Conditions in the Watershed:Soil Types, Land Cover, Topography
Pollutant Loading (Sediment, Phosporous, Nitrogen)
Stream Conditions
Areas of Frequent Flooding
Community Flood Survey Develop of Watershed Goals and Objectives
Watershed Based Plan:Recommendations of best practices and strategies.
Prioritize future actions and projects.
Sources of potential funding to assist in implementation.
Goals and Objectives: Document existing conditions.
Decrease flood damage. Improve water quality. Collaborate with multiple partners (landowners, communities, agencies, etc) for solutions and strategies.
Identify sources of funding. Educate about watershed conditions.
Establish partnerships for implementation and future actions.

We Want Your Input!
Please take our survey!Please take a moment tonight to fill out the community flooding survey for homes, businesses, and property owners in the Upper Silver Creek watershed. This will help in determining strategies and recommendations for addressing flooding problems in the watershed.
An online version of the survey is available at: www.surveymonkey.com/s/UpperSilverCreek
The survey will be open until September 12th.
Thank you for your
input and comments!

Watersheds in Madison County
Overview of Stormwater PlanThe Madison County Stormwater Plan is the overall framework for stormwater management in
the county which guides regulations, identifies flood and water quality problems, establishes best
management practices, and prioritizes work to be done.
The Upper Silver Creek watershed is one of ten watersheds that will be part of the overall
Stormwater Plan. Direction and approval for the Stormwater Plan comes from the Madison
County Stormwater Commission, whose members include County Board members and municipal
representatives.

Impaired Streams (303d listed streams, 2014)

What is an
impaired stream? Streams in Illinois are regularly
analyzed by the Illinois EPA for a variety
of conditions including biological,
physicochemical, physical habitat, and
toxicity data. Streams are analyzed
using categories including: aquatic life,
fish consumption, public water supply,
aesthetic quality, and primary contact.
Each assessed stream segment is then
rated as Fully Supporting (good), Not
Supporting (fair), or Not Supporting
(poor) for each applicable category. If a
stream is rated at fair or poor, then the
stream is categorized as “impaired” .
How many impaired
streams are there in
Illinois?Approximately 34,762 miles of streams
in Illinois are assessed on a regular basis.
This is out of a total of approximately
119,244 stream miles in Illinois. Out of
the 34,472 miles of assessed streams,
approximately 15,398 miles (44%) have
been designated as “impaired”.(1)
What is causing the
impairment?For Silver Creek, the impairment is
caused by dissolved oxygen, manganese,
phosphorus, and sedimentation. For
Troy Creek, the impairment is caused by
phosphorus.(1)

Methodology - Estimating
Pollutant LoadsOverview: Nutrient and sediment loads for the Upper Silver Creek watershed
were calculated using the Spreadsheet Tool for Estimating Pollutant Load
(STEPL). STEPL employs simple algorithms developed though scientific research
to calculate nutrient and sediment loads from different land uses.
STEPL computes watershed surface runoff, nitrogen and phosphorus loads, and
sediment delivery based on various land uses and management practices.
Data sources: The most recent National Land Cover Database (2011) was used as
the source for land use data. Animal (livestock) data was obtained from the 2012
county level agricultural census database. Runoff volumes were based on long-
term precipitation records from the Southern Illinois University weather station
at Belleville. The remaining user input parameters were obtained from the STEPL
On-line Data Access System ( http://it.tetratech-ffx.com/steplweb/steplweb.html)
Sediment calculations: The annual sediment load (sheet and rill erosion only) is
calculated based on the Universal Soil Loss Equation (USLE) and the sediment
delivery ratio. Gully and streambank erosion are based on streambank stability
assessments that are currently ongoing and will be added to the calculations
upon completion.
Note: The estimated pollutant loads are based on a model, and do not
necessarily reflect individual parcel/site conditions. The model will be used to
help evaluate best management practices (BMPs).
Note: Sediment load estimates does not include gully and streambank estimates at this time. Gully and streambank estimates are still being calculated and will be includ-ed in the Existing Conditions Report this fall.
Upper Silver Creek Watershed Plan
Water Quality Overview
Sources of Non-Point
PollutionThere are two types of water pollution:
“point source” pollution and “non-point
source” pollution. Point source pollution is
discharged through a pipe or some other
discrete source.
Non-point source pollution is the result of
many sources, when combined, can create
impaired streams, lakes, and water bodies.
Examples of non-point source pollution are
metals, chlorides, oils, trash, fertilizers (nu-
trients), pesticides, and pet waste (E. coli).
The graphics above and left illustrate com-
mon sources of non-point source pollution.Sources: Top graphic - Environmental Protection Agency; middle - University of Tennessee, Knoxville, Department of Landscape Architecture; left - NC Department of Environment & Natural Resources
Water Quality BenefitsEnsuring clean water in the Upper Silver Creek
Watershed has numerous benefits including:
clean, safe supplies of drinking water; stream,
ponds, and lakes suitable for recreation;
navigable shipping channels further downstream;
and healthy habitats that supports a wide variety
of plant and animal life.
Water Quality Benefits:
Ensuring clean supplies of drinking
water for communities.Photo Source: Bond-Madison County Water Website
Water Quality Benefits:
Ensuring lakes, ponds, and streams are suitable for recreation.

Water Quality Benefits:
A healthy watershed that supports a wide variety of plant and animal life.
Water Quality Benefits:
Helping to keep shipping channels
open downstream.

Issues
Solving all flooding problems will not happen
overnight. Long term strategies will be needed
to reduce flooding impacts in the watershed.
This plan will be an important step in the
process, especially with a mailed and online
survey in the fall of 2014 that will help
identify areas of flooding that occur outside of
designated floodplains.
Additional study and analysis will likely be
a key outcome of this process. This plan will
be a key component of the Madison County
Stormwater Plan.
Help Us Identify Existing
Areas of FloodingTonight there are detailed maps that the
planning team is using to assist in identifying
locations of existing flooding. Spend a few
minutes discussing existing areas of flooding
such as:
Locations of roads that are frequently over
topped by flood events.
Locations of homes, businesses, or structures
that are impacted by flooding.
Areas of erosion or other damage caused by
flooding or stormwater.

Recent Articles About
Watershed PlanningWatershed plans are a great way for multiple partners (local leaders, stakeholders, agencies, landowners, etc) to develop goals and objectives for the watershed. A plan will then help prioritize future actions and projects, and identify sources of funding and partners that can assist in implementation.Recent articles in FarmWeek have highlighted the benefits of watershed plans and opportunities for sources of funding such as the Conservation Reserve Enhancement Program (CREP) and EPA 319 grants.

Process to Date
The partners involved with the
process thus far (Madison County,
HeartLands Conservancy, National
Great Rivers Research and Educa-
tion Center, Madison County Soil
and Water Conservation District
and Midwest Streams) have been
working on the plan since last win-
ter. Some of the work thus far has
included:
Aerial analysis of Silver Creek
and streams to identify areas of
erosion and stream issues.
Technical analysis for the existing
conditions report.
Meetings with communities,
landowners, and other stake-
holders.
Field checks along Silver Creek
and tributaries.
The pictures to the right show
some of the work to date.
Meeting with landowners this summer.
Meeting with landowners this summer. Field check of Silver Creek to review erosion.
