Thermometers

Water temperature data is an important variable to be recorded for all kinds of stream gaging data requirements. The temperature or viscosity of the flow affects sediment suspension and deposition and may affect the roughness of a sand-bed stream.

The best or preferred method to obtain the correct water temperature is to submerge the thermometer while wading some distance out in the stream. The thermometer is held beneath the water for sufficient time (about one-half minute) to allow the temperature of the thermometer to equalize with the water temperature. The bulb of the thermometer should always remain in the water until after the reading is obtained.
