Shoreline of Clear Lake showing emergent vegetation 

 affording excellent shelter for immature shrimp. 



Salinities and temperatures in 1960-61 in Clear Lake were similar 

 to those recorded in 1958. The maximum salinity of 14. 3%o was recorded 

 June 15, I960, while the fresh-water conditions (less than 0. l%o) began dur- 

 ing the latter half of November I960 and extended into February 1961. This 

 was a slightly longer period of fresh- water conditions than recorded for pre- 

 vious years. The maximuin temperature of 40°C. was recorded June 7, I960, 

 and the minimum of 7. 6° C. was recorded December 15, I960. 



As expected, salinities in Offats Bayou were higher than in Clear 

 Lake. A maximum salinity of 33. 6%o was recorded on July 6, I960, in the 

 deep central basin of the bayou. The minimum salinity recorded was 11.4%o 

 at the head of the bayou on January 9. 1961. Temperatures ranged from a 

 high of 36. 5° C. in June I960 to a low of 8. 0° C. in December I960.
