Flow & Water Quality Sampling Keene, Merritt, Miller, Chester, Tischer, and Amity Flow monitoring 5 minute data logging equipment installed Fall 2014 Water Quality Sampling design: Spring Fall 2015-2016; 25 x per year Water Quality Field Parameters: Temperature Dissolved Oxygen (mg/l ; % saturation) ph Specific electrical conductance (EC25) 100 cm Secchi-tube reading (water clarity) Water level measurement, if at a gage station Stream photograph with field notes Water Quality Lab Parameters: E. coli Turbidity, TSS Color, Cl -, TP, TN, NO3/2-N, NH4-N (samples collected but analyses not funded as yet)
Sampling will start asap in Spring 2015 Awaiting Spring in Duluth Developed by: Updated: U6-m26-s6
Automated in-stream sensors data logged every 5-15 minutes; may be manually or automatically (via modem) uploaded to MPCA database(s), and www.lakesuperiorstreams.org with its data visualization tools Flow, temperature, DO, specific conductivity (EC25), turbidity
Seasonal, event-based field measurements Secchi tube (clarity) Appearance (foam, color, ) Staff gauge (water depth/flow)
Grab sampling for E.coli, turbidity, TSS, Grab samples for E. coli are taken with sterile containers E. coli

Chester Creek Flow Station located at W College St (St Scholastica bridge). The creek runs relatively straight and flat and is absent of upstream and downstream obstructions and appears to include a stable downstream control. The culvert provides well defined channel dimensions, is suitable for mounting equipment and measuring high flow and is accessible from the street.
Keene Creek Flow Station located at the box culvert on West 57th Ave. downstream side, on the southwest corner of Irving Park. The creek runs relatively straight and flat at the culvert and is absent of upstream and downstream obstructions and includes a stable downstream control.
Tischer Creek Flow Station located on downstream side of 4 th St. The defined channel dimensions, equipment mounting suitability, and minimal channel obstructions. make this the best of the available options on Tischer.
Merritt Creek Flow Station located at the box culvert (downstream side) on Grand Ave. The creek runs relatively straight and flat at the culvert and is absent of upstream and downstream obstructions and appears to include a stable downstream control. The culvert provides well defined channel dimensions, is suitable for mounting equipment and measuring high flow and is accessible from the street.
Amity Creek Flow Station located at Occidental Blvd. The creek runs relatively straight and flat and is absent of upstream and downstream obstructions and appears to include a stable downstream control. The culvert provides well defined channel dimensions, is suitable for mounting equipment and measuring high flow and is accessible from the street.
