SB 1.4.14

sūta uvāca

dvāpare samanuprāpte
 tṛtīye yuga-paryaye
jātaḥ parāśarād yogī
 vāsavyāṁ kalayā hareḥ

Translation: 

Sūta Gosvāmī said: When the second millennium overlapped the third, the great sage [Vyāsadeva] was born to Parāśara in the womb of Satyavatī, the daughter of Vasu.

Purport: 

There is a chronological order of the four millenniums, namely Satya, Dvāpara, Tretā and Kali. But sometimes there is overlapping. During the regime of Vaivasvata Manu, there was an overlapping of the twenty-eighth round of the four millenniums, and the third millennium appeared prior to the second. In that particular millennium, Lord Śrī Kṛṣṇa also descends, and because of this there was some particular alteration. The mother of the great sage was Satyavatī, the daughter of the Vasu (fisherman), and the father was the great Parāśara Muni. That is the history of Vyāsadeva’s birth. Every millennium is divided into three periods, and each period is called a sandhyā. Vyāsadeva appeared in the third sandhyā of that particular age.

SB 1.4.15

sa kadācit sarasvatyā
 upaspṛśya jalaṁ śuciḥ
vivikta eka āsīna
 udite ravi-maṇḍale

Translation: 

Once upon a time he [Vyāsadeva], as the sun rose, took his morning ablution in the waters of the Sarasvatī and sat alone to concentrate.

Purport: 

The river Sarasvatī is flowing in the Badarikāśrama area of the Himālayas. So the place indicated here is Śamyāprāsa in Badarikāśrama, where Śrī Vyāsadeva is residing.
