Abstract
Analyses of a variety of climatic variables generated from 80 years (1901-80) of daily precipitation and temperature data collected by the National Weather Service showed that Nacogdoches is characterized by a humid subtropical climate with an average annual precipitation and temperature of 45.96 inches and 65.5°F, respectively. The summer is warm and dry with mean maximum temperature of 91.6°F while winter is mild with mean minimum temperature of 38°F. There were no statistical differences between mean annual temperature and precipitation on the 1951-80 and 1901-80 periods or between any 2 normal periods. Rain days occurred once in every 4 days with 32% of rain days lasting only a day. The longest annual dry spells ranged from 13 to 53 days with an average of 22 days. The earliest and latest dates of frost recorded at Nacogdoches were October 15 and April 15, respectively. Recorded maximum and minimum temperatures recorded in this area were 110°F and -4.0°F, respectively. Regression equations have been developed to estimate mean annual streamflow of La Nana Creek, pan evaporation, daily temperature, maximum storm intensity, and hay production. Runoff coefficient for La Nana Creek was 0.30 and maximum flood stage was 286.41 ft. above sea level. Flow duration patterns of the Creek may have been altered significantly by urbanization in the recent 9 years.
