Hey Jan,

I didn’t include the historical Harris precipitation gauge in the model, since the assumption is that this data would no longer be available.

Here’s the latest significant parameters and their respective multipliers within the best model so far:

Carnation Flow: 0.9333
Cowichan Flow: 0.03818
Cowichan Flow on previous day: -0.03618
Chemainus Flow: 0.01565
Chemainus Flow on previous day: -0.03151
Chemainus Flow on 2 days previous: 0.01582
Nanaimo Flow: 0.02235
Englishman Flow: 0.07033
Englishman Flow on previous day: -0.0391
Cowichan Lake Forestry Rain Gauge: 0.03187
Cowichan Lake Forestry Rain Gauge from previous day: 0.04635
Sooke Lake North Rain Gauge from previous day: 0.04580
Port Renfrew Rain Gauge: -0.01606
Port Renfrew Rain Gauge from previous day: 0.01579

This predictive model has a very high correlation (r^2=0.96) with the actual values over the past 6 years. We’re not quite done yet, but this may be about as good as it gets.

cheers,
Stephen
