Chanzo cha mto huu ni eneo linaloitwa Begha (kati ya Port Alfred na East London). Mnamo 1858 meli ya mvuke Madagascar ya Rennie line ilipotea baada ya kugonga matumbawe karibu na chanzo cha mto Birha, majira ya usiku mnano tarehe 3 Desemba. Majaribio kadhaa yalifanyika kuiokoa meli isizame, hata hivyo yalishindikana na kupelekea meli hiyo kuvunjika mnamo tarehe 4 Desemba. Hakuna aliyepoteza uhai.
