Wolf Lake Background
• 804 ha (450 acres)• Once part of Lake Michigan, but then 19th century
industrialization and roads disconnected it• Maximum depth of 5.5 m (18 feet)• Habitat for many species including– Franklin ground squirrel (Spermophilus tridecemlineatus)– Lake sturgeon (Acipenser fulvescens)– Black-crowned night heron (Nycticorax nycticorax)

Restoration
Pool #9
Pool #8
•Controls exotic species, creates new environments and diversity•Dredging in pool #9 to be caught by filtering wetland strips so it doesn’t contaminate pool #8

Field SiteThe area surveyed consisted of:
•Main shoreline stretching 370 linear meters
•13 islands

Survey Technique for Main shore
Plot setup:1. Marker pole placed
every 20 meters• Made 36
shoreline plots2. 1x1meter plot set at
every pole3. Point-contact
method conducted4. Species identified
and tallied

Surveying the Islands
1. Shore line• 1x1meter plots every 20
meters2. Water line• 1x1meter plots every 20
meters3. Upland• 1x1meter plots every 10
meters

Water and Algae SamplingAlgae
• 25 buckets of water poured through filter
• Algae trapped in container at bottom
• Algae identification and volume to be assessed at a later date
Water• Dissolved oxygen
– Manganous Sulfate and Alkaline Iodide-Azide reagents
– Titration using Phenylarsine Oxide
• Conductivity• pH
