within the canals between 0830 and 1130 hr from 

 August 1970 through August 1971. Also, a hy- 

 drological control station, Station 1, was estab- 

 lished in the bayou adjacent to the development 

 site to monitor ambient water conditions in a 

 natural area (Figure 3). Hydrological factors 

 were recorded from surface and bottom water 

 and included water temperature, dissolved oxy- 

 gen, and salinity. Temperature was recorded 

 to the nearest tenth of a degree with a handheld 

 mercury thermometer; dissolved oxygen was de- 

 termined by a modified Winkler method (Strick- 

 land and Parsons, 1968); and salinity was de- 

 termined with a Model 10401 TS Goldberg re- 

 fractometer'. 



Fish and invertebrates were collected with a 

 4.8-m otter trawl composed of a 2.5-cm stretched
