Lake Simcoe Region Conservation Authority A Watershed for Life
Lake Simcoe
- 60 km north of Toronto- Watershed: 3,307 km2
▫ Lake: 722 km2
- Depth max: 42 m (mean = 15 m)- 435,500 residents
▫ (+50,000 seasonal)
- $200 million recreational fishery
Map: Wilson 2008

-Phosphorus loading: 2007-2011 average = 91 tonnes (LSPP target = 44 tonnes)
- Deepwater Oxygen: <5 mg/L (LSPP target = 7mg/L)
-Invasive species
-Climate change
- Watershed development▫Road salt!!!!

Routine WQ monitoring programs- LSPP (Lake Simcoe Protection Plan) sites▫ 28 sites (one autosampler) + quality control samples▫ Sampled every two weeks, every three weeks in winter▫ Plus extra event sampling, especially during spring freshet
- PWQMN sites▫ 12 sites (8 overlap with LSPP)▫ Sampled monthly during ice-free season (8X per year)
- LSPP atmospheric sampling▫ 7 sites (3 sites in winter) + QC samples▫ Weekly (every three weeks in winter)
6
Lake Simcoe Region Conservation Authority A Watershed for Life
Other WQ monitoring programs- Limnology water quality and sediment- Groundwater- Turbidity (4 sites)- Conductivity (6 sites)- LSCUF and LSGBCUF projects▫ Autosamplers at three sites (temporary)
- Subwatershed plans, Biocriteria, Toxic Screening- Historic sites

Historical data – WISKI 6
- Migrated water quality data from WISKI 6 to 7- Tried three times▫ Units were ignored
e.g. PPUT value of 50 µg/L was listed as 50 mg/L
▫ Date artifact that could not be fixed▫ Gave up!
- Remained in limbo for a long time- Blessing in disguise!▫ Recreated everything from scratch▫ And improved the structure

Historical data – WISKI 6- Loss of all scripts▫ Different scripting language▫ Decided not to have Kisters re-write them for us▫ Better to write in-house with assistance from Kisters
For two reasons: cost and data knowledge
- Still have not caught up with historic data imports!▫ From WISKI 6 and excel files
- House cleaning still required!▫ Artifact parameters need to be deleted ▫ Requires care and attention to detail

Water Quality Data – WISKI 7- Five Measuring programs
1. LSPP_Atmospheric2. LSPP_Tributaries3. PWQMN_Tributaries4. Limnology5. Limnology_Sediment

Flow Chart – Setting things up using KiWQM Configuration
- Parameters ▫ Parameter type (PPUT, CLIDUR, etc.)▫ Analysis methods▫ Parameter method combination
- Parameter Lists▫ Certain parameters assigned to each list
- Measuring Programs▫ Assign stations▫ Assign parameter list

Water Quality Data – WISKI 7
12
Lake Simcoe Region Conservation Authority A Watershed for Life
Water Quality Data – WISKI 7- Data QA/QC• Best done before data is in WISKI• Data format must match exactly to the import
configuration file• No blank values• Replicate values can be included in file• Correct Units

Water Quality Data – WISKI 7
15
Lake Simcoe Region Conservation Authority A Watershed for Life
Water quality in hydrology module
Continuous data:- Turbidity - Conductivity
Sampling status:- Up-to-date sampling points on the hydrograph
16
Lake Simcoe Region Conservation Authority A Watershed for Life
Reporting- Phosphorus Loading Reports▫ Calculations using phosphorus, flows and
precipitation
- Watershed Report Cards▫ Grading using comparison of phosphorus to
PWQO (and benthic information)
- Subwatershed Plans▫ Comparison of several parameters to WQ
Objectives, trend analysis (long and short-term)
- Environmental Monitoring Report- Science Newsletters (e.g., Turbidity and TP)- Research
17
Lake Simcoe Region Conservation Authority A Watershed for Life
Data Analysis- Most data analysis is done outside of WISKI▫ Became a habit when we were in limbo
- Quality control of turbidity/conductivity▫ Range related editing, amplitude tool
- “Quick” regressions in WISKI▫ TSS vs TP, for example▫ Times do not always match
18

Scripts and agents- Purpose: Assist with phosphorus load calculations- Agent: Aggregate of phosphorus from all analytical
methods for each monitoring program- Agent: Merges together phosphorus concentrations
from both programs (LSPP and PWQMN) - Script: Midpoint method
19

Aggregate
20

Merger
21
Lake Simcoe Region Conservation Authority A Watershed for Life
Midpoint ScriptMidpoint method (Scheider 1979)
▫Estimate concentrations for days between samples▫Half with first concentration,Half with second concentration
22
Lake Simcoe Region Conservation Authority A Watershed for Life
Wish List - Loads- Tributary loads (TP, chloride, nitrogen, TSS)▫ Concentration X flow▫ Gauged, ungauged, unmonitored subwatersheds▫ Prorating to mouth required
- Bulk application of time series creation- Other loads (Polders, Atmospheric, WPCP, septic) - Midpoint method using linear interpolation- Use of turbidity for load estimates- Atmospheric, phosphorus outlier detection- Everything as automated as possible!
23
Lake Simcoe Region Conservation Authority A Watershed for Life
Wish List - Other- Key Lists (sample descriptions)- Alarms (turbidity)- Comparator lists (WQ objectives)- Using turbidity or conductivity to determine WQ
objective exceedances - KPI (ecological health key performance indicators,
percentiles in WISKI)

TipsFeeling Overwhelmed?- Tough learning curve, but gets better!- Keep trying, eventually things will make more sense!- Learn from others, ask Kisters questions- Time: Huge task, not for one person▫ Tricky to balance other work and make time for WISKI
Technical tips:- Alphabetical order (Parameters)- Static copies of calculated time series- Consistency (naming conventions, EST/EDT)- Be careful about updating versions (loss of integrity)- WISKI 7 is much more forgiving and flexible than WISKI 6
25

Notes to the group- Consistent naming conventions among organizations
(for WQ parameters)▫ To ease potential grouping of data
- Central Hub or Conglomerate▫ Interested? ▫ Suggestions?

Load
Monitored/gauged subwatersheds▫ Daily load time series uses:
flow (pro-rated) and concentration (midpoint) time series and a formula
▫ Annual load time series (sum of daily loads)
Monitored/ungauged subwatersheds▫ Flows estimated from gauged areas using a formula:▫ Sum of all gauged flows divided by gauged area multiplied by ungauged subwatershed area
Unmonitored/ungauged subwatersheds▫ Loads calculated outside of WISKI ▫ Annual load estimated on an areal basis
