About this water

The Luna flows through spectacular mountain limestone country above Villablino — a 45 km freestone river of outstanding clarity and selective browns. Emerges from a dramatic slate gorge with excellent insect habitat and productive pocket-water. Dam regulation maintains consistent summer flows supporting strong mayfly and sedge hatches April–July. The 5-hour response time and excellent clarity make this ideal for technical dry-fly work.
