includes the North Newport River and lower 

 parts of its tributaries from the lower end of 

 Carrs Neck Creek (trawl station 10) upstream 

 to station C. The upper reach extends from 

 Payne Creek to the mouth of Riceboro Creek 

 (station F) . I generally treat these two sections 

 as a unit for convenience. 



Because salinity varies so greatly, this section 

 of the estuary only roughly corresponds to the 

 zones recognized by Carriker (1967). He rec- 

 ognized salinity ranges of 5 to \%%c for the up- 

 per reach and 18 to 25Ar for the middle reach. 



Habitat 5: Oligohaline creek (Figure 6). — 

 The North Newport River originates at the con- 

 fluence of Peacock and Riceboro Creeks. Oligo- 

 haline sampling stations were located in the 

 oligohaline section of Riceboro Creek (Figure 2) . 

 Most fishes were collected in Riceboro Creek at 

 station G and the lower part of Crossroads Creek 

 where it joins Riceboro Creek near the town of 

 Crossroads. Crossroads Creek was recently di- 

 verted into Riceboro Creek above the station by 

 the State Highway Department, thus eliminating 

 the station. Salinity and temperature ranges 

 are given in Table 1. A temperature-salinity 

 diagram (Figure 7) indicates that salinity gen- 

 erally increased with rising tide except when 

 fresh water prevailed throughout the tidal cycle. 

 In winter water temperatures were lowest at 

 low tides. 



Habitat 6: Freshwater creek. — Seven fresh- 

 water or limnetic stations in Coastal Plain 

 creeks, free from the influence of salt water, are 

 called "freshwater stations" in the text. The 

 first six of these stations are in the North New- 

 port River drainage in Liberty County and were 

 sampled on 13 May 1968. The seventh is in the 

 Ogeechee drainage in Chatham County and was 

 occupied on 9 March 1969. Location of these 

 collections are as follows: (1) Upper South 

 Newport River at U.S. Highway 17; (2) Head- 

 waters of Payne Creek on U.S. Highway 17, 2 

 miles west of Riceboro; (3) Tributary of Rice- 

 boro Creek about 2.5 miles north of Crossroads 

 on a county road ; (4) Peacock Creek, 2 miles 

 southeast of Mcintosh, on dirt road off U.S. 

 Highway 82; (5) Goshen Swamp Creek on U.S. 

 Highway 82, 2 miles south of Flemington; (6) 

 Peacock Creek at Solomon Temple, between
