Ash Creek/Rooster River
      Watershed

  An overview presented by the
Ash Creek Conservation Association

      L. Kraig Steffen, Ph. D.
My Background

 Ph.D in Organic Chemistry
 Actively involved in Science Education
 Lifelong interest in Ecology and
  Environmental Science
 NOT an expert on Watersheds! I’m
  sharing this as a concerned citizen
What is a Watershed?


 Simply put, it is a geographic region
  drained by a particular creek, stream, or
  river.
 Usually defined by the largest river that
  drains into a body of salt water.
A simple thought experiment..
 When a drop of rain falls where does it go on
  its journey back to the sea? The Pacific? The
  Atlantic? Gulf of Mexico? Long Island Sound?
 Where would its “neighbor” go?
 Now, consider 4 million neighbors!
 The geographic region defined by the
  collective drainage of these raindrops defines
  a watershed.
 Size varies widely, the Mississippi drains
  millions of square miles, our local watershed
  about 15 square miles
A Simple Watershed
Does all the water return to
            the sea?
 Eventually, yes…
 However, it may seep into the ground
  and become part of an aquifer. The
  water in aquifers may stay underground
  for days.. Or years.. Or even centuries
 The water may also evaporate back into
  the atmosphere
Now, lets add some complex features…
Who Cares??
 We all should…
 We need fresh water     to drink
 We need fresh water     for growing food
 We need fresh water     for the plants and
  animals that are part   of our
  environment
The Value of a River
 Rivers drain away excess water, ie flood
  control
 Rivers provide fresh water habitat
 Rivers provide a source of water for the rich
  Riparian biomes surrounding them.
 “Riparian” means essentially near a river.
  Riparian zones are often the most diverse
  habitats in a given region, a linear “oasis” if
  you will.
 Rivers are important for commerce and
  leisure activities
Riparian and Salt Marsh Habitat
 Great variety of plants and animals
 Aesthetically pleasing
 Ecologically critical as a source of food and it
  functions as an important waste control
  system - natural biofiltering
 Salt marsh habitat is critical for biofiltering
  and as a home to a diverse collection of
  plants and animals
The Rooster River
 Small, only about 10 miles long, entire
  watershed is only 15.3 square miles
 Ash Creek, our local salt marsh estuary, is the
  outlet of the Rooster River
 Tidal flux goes up to just past the Mount
  Grove cemetery
 So .. Lets look at a map!
Aerial Map of Rooster River/Ash Creek




                    QuickTime™ and a
          TIFF (Uncompressed) decompressor
             are needed to see this picture.
Familiar Road Map…
And for the careful analysis of the actual
watershed shape, the topographic map
Ash Creek/Rooster River Watershed

A quick visual tour - going
upstream from the mouth of
the Ash Creek Tidal estuary
Rooster River watershed
meets the Sound at the Ash

What Affects our Watershed?
   Natural factors like total rainfall and geography
   Climate: hot and wet? cold and dry?
   Tidal flux
   Agriculture and Landscaping use
   Urbanization
   Industrial Pollution
“They Paved Paradise and Put
      up a Parking Lot”
 One major effect of urbanization is
  simply the covering of the ground with
  less permeable harder surfaces
 Creates much faster moving runoff
 Keeps water from seeping into the soil
 Exacerbates erosion
 Depletes the underground water supply
Pollution
 Point Pollution: A well defined release point
  for pollutants. Sewage Treatment plant,
  Factory, Research Facility
 Non Point Pollution: agricultural spraying,
  landscape maintenance, vehicle emissions,
  dry deposition from remote sources
 Myriad of harmful effects on our local
  watershed - exposure to toxic materials, algal
  blooms, long term degradation of the habitat
Pollution Information…
 The internet has made it much easier to
  find information
 The internet has made it harder to
  validate information!
 Look for reliable, long standing sources
  but keep an open mind
 www.scorecard.org
Using “Scorecard”
A Plethora of Problems
 Storm Runoff from west side STP
 Industrial wastes from current,
  historical manufacturing
 Non point pollution
Heavy Metal/POP Pollution
 Geographical Distribution and Potential
  for Adverse Biological Effects of Selected
  Trace Elements and Organic Compounds
  in Streambed Sediment in the
  Connecticut, Housatonic, and Thames
  River Basins, 1992-94
 USGS Water Resources Investigations
  Reportハ97-4169By Robert F. Breault and
  Sandra L. Harris
TMDL
 Total Maximum Daily Load
 Measures bacteria in water
 Expressed as Percentage decrease
  needed to meet maximum
  recommended levels
 Rooster river is on the 2004 list for not
  meeting water quality standards
What Can I DO??
         (a lot actually!)
 Work to encourage honest and
  thorough pollution reporting
 Support Remediation Efforts
 Hold Politicians Accountable
What Can I do?
           At Home?
 Replace high maintenance lawns with native vegetation and
  mulch
 Compost your lawn and garden waste, e.g. leaves, grass
 Use porous materials for driveways & sidewalks
 Sweep driveways, sidewalks & roads rather than using a hose
 Avoid use of pesticides
 Pick up after pets
 Use, store, and dispose of chemicals properly (in Bridgeport
  residents can bring their toxic chemicals to the transfer station
  on Asylum street once a year)
 Use a car wash instead of washing car at home
 Prevent storm drain dumping
Why?

Ash Creek/Rooster River Watershed

  • 1. Ash Creek/Rooster River Watershed An overview presented by the Ash Creek Conservation Association L. Kraig Steffen, Ph. D.
  • 2. My Background  Ph.D in Organic Chemistry  Actively involved in Science Education  Lifelong interest in Ecology and Environmental Science  NOT an expert on Watersheds! I’m sharing this as a concerned citizen
  • 3. What is a Watershed?  Simply put, it is a geographic region drained by a particular creek, stream, or river.  Usually defined by the largest river that drains into a body of salt water.
  • 4. A simple thought experiment..  When a drop of rain falls where does it go on its journey back to the sea? The Pacific? The Atlantic? Gulf of Mexico? Long Island Sound?  Where would its “neighbor” go?  Now, consider 4 million neighbors!  The geographic region defined by the collective drainage of these raindrops defines a watershed.  Size varies widely, the Mississippi drains millions of square miles, our local watershed about 15 square miles
  • 6. Does all the water return to the sea?  Eventually, yes…  However, it may seep into the ground and become part of an aquifer. The water in aquifers may stay underground for days.. Or years.. Or even centuries  The water may also evaporate back into the atmosphere
  • 7. Now, lets add some complex features…
  • 8. Who Cares??  We all should…  We need fresh water to drink  We need fresh water for growing food  We need fresh water for the plants and animals that are part of our environment
  • 9. The Value of a River  Rivers drain away excess water, ie flood control  Rivers provide fresh water habitat  Rivers provide a source of water for the rich Riparian biomes surrounding them.  “Riparian” means essentially near a river. Riparian zones are often the most diverse habitats in a given region, a linear “oasis” if you will.  Rivers are important for commerce and leisure activities
  • 10. Riparian and Salt Marsh Habitat  Great variety of plants and animals  Aesthetically pleasing  Ecologically critical as a source of food and it functions as an important waste control system - natural biofiltering  Salt marsh habitat is critical for biofiltering and as a home to a diverse collection of plants and animals
  • 11. The Rooster River  Small, only about 10 miles long, entire watershed is only 15.3 square miles  Ash Creek, our local salt marsh estuary, is the outlet of the Rooster River  Tidal flux goes up to just past the Mount Grove cemetery  So .. Lets look at a map!
  • 12. Aerial Map of Rooster River/Ash Creek QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture.
  • 14. And for the careful analysis of the actual watershed shape, the topographic map
  • 17. A quick visual tour - going upstream from the mouth of the Ash Creek Tidal estuary
  • 18. Rooster River watershed meets the Sound at the Ash Creek Tidal estuary

  • 36. What Affects our Watershed?  Natural factors like total rainfall and geography  Climate: hot and wet? cold and dry?  Tidal flux  Agriculture and Landscaping use  Urbanization  Industrial Pollution
  • 37. “They Paved Paradise and Put up a Parking Lot”  One major effect of urbanization is simply the covering of the ground with less permeable harder surfaces  Creates much faster moving runoff  Keeps water from seeping into the soil  Exacerbates erosion  Depletes the underground water supply
  • 38. Pollution  Point Pollution: A well defined release point for pollutants. Sewage Treatment plant, Factory, Research Facility  Non Point Pollution: agricultural spraying, landscape maintenance, vehicle emissions, dry deposition from remote sources  Myriad of harmful effects on our local watershed - exposure to toxic materials, algal blooms, long term degradation of the habitat
  • 39. Pollution Information…  The internet has made it much easier to find information  The internet has made it harder to validate information!  Look for reliable, long standing sources but keep an open mind  www.scorecard.org
  • 41. A Plethora of Problems  Storm Runoff from west side STP  Industrial wastes from current, historical manufacturing  Non point pollution
  • 42. Heavy Metal/POP Pollution  Geographical Distribution and Potential for Adverse Biological Effects of Selected Trace Elements and Organic Compounds in Streambed Sediment in the Connecticut, Housatonic, and Thames River Basins, 1992-94  USGS Water Resources Investigations Reportハ97-4169By Robert F. Breault and Sandra L. Harris
  • 43. TMDL  Total Maximum Daily Load  Measures bacteria in water  Expressed as Percentage decrease needed to meet maximum recommended levels  Rooster river is on the 2004 list for not meeting water quality standards
  • 44. What Can I DO?? (a lot actually!)  Work to encourage honest and thorough pollution reporting  Support Remediation Efforts  Hold Politicians Accountable
  • 45. What Can I do? At Home?  Replace high maintenance lawns with native vegetation and mulch  Compost your lawn and garden waste, e.g. leaves, grass  Use porous materials for driveways & sidewalks  Sweep driveways, sidewalks & roads rather than using a hose  Avoid use of pesticides  Pick up after pets  Use, store, and dispose of chemicals properly (in Bridgeport residents can bring their toxic chemicals to the transfer station on Asylum street once a year)  Use a car wash instead of washing car at home  Prevent storm drain dumping
