| Lehigh River American Shad |
 |
| The staff from Fisheries Management Area 5 (Bushkill) has completed monitoring of shad passage through the Easton Dam (RM 0.0) fishway for the 2012 spawning migration. Monitoring was discontinued at the Chain Dam (RM 3.0) fishway due to its inability to successfully pass shad. At Easton, surveillance equipment was started 23 March 2012 and terminated 29 June 2012. The early start was due to the unusual warming trend during the spring, which was thought to have jump started shad passage earlier than traditional runs.
A minimum of 2,096 adult American shad passed the Easton Dam fishway in 2012 (Table 1). The passage of the first recorded American shad was on 23 March with shad being recorded through 28 June. Multiple peaks in passage were observed 16 April through 22 April (n = 453 shad), 1 May through 15 May (n = 507 shad), 17 May through 1 June (n = 934 shad), and 8 June through 14 June (Figure 1). Generally passage was very low and sporadic prior to 16 May, with less than 10 individuals observed passing. Throughout May and June, passage of shad occurred daily although no passage of shad was observed 27 March through 13 May. Passage was recorded throughout the 24-hour period with the greatest movement (98.6%, n = 2,067 shad) occurring from 0500 through 2100 hours
