Clover Groff Impairments

• According to the Big Darby Creek TMDL
• Clover Groff is designated MWH
• (In non-attainment of WWH)
• Low dissolved oxygen
• Nutrients
• Unionized ammonia
• Siltation
• Sediment metals

12
Habitat Modifications

• Channelization
• Hydro-Modification
• Ditching
• Dredging
• Deepening
• Straightening
• Removal of riparian
• vegetation

Channel Morphology
Entrenched or Incised
Maintained due to lack of stream energy

Existing Biological Condition

• QHEI 35 WWH QHEI 60
• IBI 24
• HMFEI Macroinvertebrate 11
• Non-Attainment of Warm Water Habitat

Project Goals

• Return Clover Groff ditch to a functional stream
  with an accessible floodplain.
• Provide an ecosystem that will meet an aquatic
  life use designation of WWH water quality
  criteria.

17
Use QHEI as our Design Tool
18

• TDML Target for WWH
• QHEI scores 60

• Substrate 13
• Channel 14
• Riparian 5

19
High Moderate Influence Attributes

• High Influence
• Silt/Muck Substrates
• Sparse Cover

• Moderate Influence
• Channelized Recovering
• Low Sinuosity
• Poor Channel Development
• Hardpan Substrate Origin
• No Fast Current
• Heavy Substrate Embeddedness

20
Proposed Restoration Plan
Floodway Concept Rosgen Priority 2
21

• Stable channel geometry based on regional curves
  and reference reaches

• Increase sinuosity or overall stream length

22
Addition of Substrate
1,200 tons of sand gravel substrates
Construction of riffle/pool complexes
23
In Stream Cover
Boulders
Fish Lunkers Overhanging Vegetation Woody Debris
24
Riparian Plantings

• White Oak
• Red Oak
• Red Maple
• Washington Hawthorn
• Redbud
• Honeylocust
• Tuliptree
• American Crannyberry
• Serviceberry
• Southern arrowwood
