s

(Threatened)


Goals

Other Indigenous

Aquatic
Life and Wildlife

Reduce Invasive Species (Eurasian Watermilfoil /
Coontail) by increasing education and implementing IPM
strategy.

Reduce excessive sediment

and nutrient

inputs
throughout the watershed.

Coldwater Fishery

Protect fishery by improving stormwater management
measures.

Reduce water temperature by re
-
establishing riparian
buffers.

Partial / Total Body Contact
Recreation

Protect recreational uses by reducing the input of E.coli
into the watershed


Desired Uses


Goals

Groundwater / Drinkable
Water

Ensure groundwater and surface water quality
throughout watershed.

Unique Habitat

Identify critical habitat for endangered / threatened
species and ways to protect their habitat.

Open
Space

Establish permanent easements and nature preserves
within the watershed.

Implement cluster development ordinances.

Increase buffer zone along streams and implement
waterfront overlay.

Public Access / Recreation

Protect and preserve current access sites along Duck
Creek and Duck Lake.

Navigation

Reduce Invasive Species throughout the watershed.
Concentrate on Eurasian Watermilfoil / Coontail in
Duck Lake.

Reduce sediment

and nutrient

inputs throughout the
watershed.
