Figure 7. Effect of drought on streamflow and ground-water levels, 

 Barksdale and others (I966). 



After 



Drought conditions can end rapidly as illustrated by the events 

 of August 1955 in coastal Connecticut. This area had been experiencing a 

 moderate drought during July of 1955 but two August hurricanes resulted in 

 2.5 times the normal monthly precipitation. As a result the Palmer Drought 

 Index went from moderate drought to extreme wet spell values in a one month 

 interval . 



4.0 FRESH SURFACE-WATER BODIES 



Fresh surface-water bodies include approximately 75 streams of 

 various size that drain into Long Island Sound and numerous lakes and ponds. 

 All of the streams located on both shores of the Sound are tidal in their 

 lower reaches and are hydraul ical ly connected to adjacent ground-water reser- 

 voirs. Streamflow is derived from direct runoff of precipitation and ground- 

 water discharge both within and out of the Long Island Sound Region. Flow 

 characteristics of the streams vary depending on precipitation, on drainage 

 area, on basin characteristics such as geology, slope and the degree of 

 urbanizat ion,and on effects of man-made diversions.
