APPENDIX b Suspected Causes of Observed Problems Recommendations Visual Assessment Left bank property is kept groomed by property owners Reach Number: General Location in Watershed: Channel Condition: Hydrologic Alteration: Riparian Zone: Bank Stability: Water Appearance: Nutrient Enrichment: Barriers to Fish Movement: Instream Fish Cover: Pools: Invertebrate Habitat: Canopy Cover: Manure Presence: Riffle Embeddedness: Overall Score (Total divided by number scored) Rank 15MCMt 16MCEe 16MCEtb 16MCEtd Fourth Avenue/ Nineth Avenue Fourth Avenue/ Eleventh Avenue King Street/ Nineth Avenue King Street/ Eleventh Avenue Moote Road/ Twenty Mile Road Maple Street/ Twenty Mile Road Flows adjacent to Staff Avenue 10 10 10 5 10 10 10 8 8 10 5 7 7 8 5 10 5 5 8 7 9 7 8 8 3 8 8 7 7 9 7 3 8 9 8 8 10 8 4 9 9 8 10 10 1 1 10 10 10 10 10 10 10 5 10 10 8 7 3 7 7 7 7 10 10 10 10 7 10 10 10 10 10 7 10 10 10 n/a n/a n/a n/a n/a n/a n/a n/a 10 10 10 n/a n/a n/a 8.4 9.3 7.6 5.8 8.1 8.8 8.8 Good Excellent Good Poor Good Good Good Increase the size and the amount of native species found within the buffer Plant buffer adjacent to residential properties; Monitor sediment deposition and debris jams for any future problems Increase the size of the buffer on the residential properties Increase buffer zone; Make changes to the culvert so that it no longer acts as a fish barrier Plant woody vegetation along the banks; Monitor sediment accumulation Identify possible upstream locations where sediment may be entering the channel and monitor sediment accumulation along the bed Long term monitoring of sediment accumulation; Determine possible upstream sources of sediment Adjacent to residential property a small area with no buffer; Sediment deposits, a large number of debris jams present (can cause lateral adjustments) Lack of riparian zone adjacent to residential properties; Slope of the streambed can contribute to erosion; Fish barrier present in the form of an earthen berm impoundment with spillway Channel incision has created a fish barrier at the King Street culvert; The slope of the escarpment can lead to high shear stresses and the bank soils have a high susceptibility to erosion; Buffer zone is small adjacent to residential properties Sediment has accumulated along the streambed; Downstream of Moote Road there is few woody vegetation present along the banks Bed is flat; sediment deposition occurring upstream; Evidence of planimetric form adjustment (flood chute, large depositional feature) in upstream reach; Sediment accumulation can cause lateral channel changes A concern identified along this field site includes the accumulation of sediment along the bed which may have an impact on fish and invertebrate 16MCMc 16MCMe 16MCMf
