? = 1-9 hours of data missing (Average includes estimations) 1 Temperatures are weighted averages based on individual penstock flow and temperature

! = 10 or more hours of data missing (Average not calculated) Highlighted cells in the TCD column indicate a TCD change was made on that day

# = Station out of service 2 Current control point (see page 3 for more details)

↑ = Record high air temperature 3 NFH is only reported in October, November and December

↓ = Record low air temperature 4 APR = Airport Road. This is a virtual site interpolated linearly between CCR and BSF based on distance.
