Sustainability Master Plan
Effect of Runoff on Stream
Negative Effect on Lake Carnegie
Final Pre-Restoration Assessment
Why this first order stream?
Assessment
Geomorphology (Stream)
Substrate, flow, bank-full width, streambed, step pools etc.
Water Nutrient Quality (Stream & Lake) (assessed in Lab)
Nitrates, phosphates, ammonium, dissolved oxygen, etc
Physical Parameters using YSI instrument (Stream & Lake)
pH, turbidity, conductivity, temperature, etc.
Riparian Buffer Zone (Stream)
Bank/soil, tree species richness, vegetative cover biodiversity

Additional Phase of Assessment:
Macroinvertebrates
Merges Nutrients and Riparian studies
Bioindicators of stream health
Allows additional study of biodiversity and richness of stream life
Cost effective, easy, and quick
Popular assessment of small order water systems (Yale Forestry)
Better assessment of long term damage and aquatic populations
Collection Method
Easy template to be repeated:
Collect 5 L of water and soil from disturbed benthic region at each
site using small mesh dip nets and large kick net
Return to lab and sort
Identify using Key to Macroinvertebrate Life
Record and enter into Hilsenhoff Biotic Index
