Matsya Purana — Soma
सरित्सरस्तडागानि पुष्करिण्यश्च सर्वशः परान्नान्यभिकाङ्क्षन्तः काल्यमाना इतस्ततः //
saritsarastaḍāgāni puṣkariṇyaśca sarvaśaḥ parānnānyabhikāṅkṣantaḥ kālyamānā itastataḥ //
Rivers, lakes, ponds, and lotus-tanks were everywhere; and, being urged on from place to place, they sought no other refuge than these.
This verse does not directly describe Pralaya; it emphasizes the pervasive presence and protective/refuge-like role of waterbodies (rivers, lakes, ponds, temple tanks), suggesting their centrality as sanctifying supports in worldly life rather than cosmic dissolution.
By highlighting rivers and tanks as the primary refuge sought, it aligns with the dharmic duty to protect, maintain, and endow water-reservoirs—kings through public works (tadāga, puṣkariṇī), and householders through supporting tīrthas, cleanliness, and ritual bathing practices.
Ritually, it foregrounds bathing and reliance on sacred waters; architecturally (Vāstu/temple planning), it supports the importance of building and maintaining puṣkariṇīs and tadāgas as integral to temple complexes and settlement water-management.
