2
Sustainability Master Plan Effect of Runoff on Stream Negative Effect on Lake Carnegie Final Pre-Restoration Assessment Why this first order stream?
3
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
4
Water Quality Focus: Nutrients
5
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
6
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
