The viscosity of water is almost linear between 50 and 70 degrees F. It is 8.7 at 50 deg and 6.4 at 70 deg F. The units are u x 10^4 lb/ft - sec. So there is an approx. 26 % change in viscosity over that limited temperature range. The water is coming from some unknown depth underground and should almost be a constant temperature, over a 24 hour period, when it reaches the surface.
