About this water

The Rio Chama is northern New Mexico's red-rock river — a dam-influenced freestone winding through O'Keeffe country below El Vado and Abiquiu reservoirs, holding browns and rainbows in handsome desert canyon water. It needs to be fished by reach rather than as one thing: the regulated water below the dams behaves like a tailwater with managed releases, while other stretches run warmer and more general. Releases, monsoon colour, winter access and private-land boundaries all shape a given day. Pick your reach, check the release and the access, and it's a scenic, rewarding river that fishes well when the flows are right. Just don't treat 'the Chama' as a single venue — the river changes character with every dam and bend.
