Effect of Runoff on Stream
Negative Effect on Lake Carnegie
Final Pre-Restoration Assessment
Why this first order stream?
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
Assessment
Water Quality Focus: Nutrients

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
Additional Phase of Assessment: Macroinvertebrates
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
Collection Method
Data: Washington Sream
Pollution Tolerance Value (Tv) assigned to each organism and number of organisms entered into Illinois RiverWatch Hilesenhoff Biotic Index:
