The Wakamarina River is a significant tributary of the Pelorus River, flowing through the Marlborough region on New Zealand's South Island. It is characterized as a small, clear stream that offers a challenging yet rewarding fishing experience for dedicated anglers. The river's character is defined by its clear, skinny water during summer low flows, which makes fish particularly wary, and by sections with overgrown banks that present casting difficulties. While fish numbers can vary significantly from year to year, the river is known to hold a quality stock of trout, often of good size, spread across its long, wide pools.
