About this water

A western Latvia river where sea trout run from winter through spring, one of several coastal Baltic waters where anglers reliably find them in that window. Sandstone freestone bedrock underlies the river, giving a clean, stable streambed well suited to swung flies and a searching approach. Atlantic salmon are also present here, managed under national and EU Baltic conservation rules with quotas, size limits and seasonal restrictions; catch-and-release is widely applied — check current rules before fishing.

Under the surface

The Irbe forms where the Stende and the Rinda rivers meet in the forests of Kurzeme, western Latvia, and runs some thirty-two kilometres to the Baltic on the Irbe Strait, near the windswept cape of Kolka. It is a lowland coastal river of soft, dark, lightly stained water over a sand-and-gravel bed, threading the pine forest and dune country of the Kurzeme coast on a gentle gradient. This is some of the finest sea-trout country in the eastern Baltic: from autumn through spring the sea trout patrol the surf zone and the river mouth, running up the Irbe to spawn, and the river fishes catch-and-release for them through much of the year. Salmon share the run. The character is quiet, sandy, forest-lined water with steady runs and modest pools. Wading is easy on firm sand and gravel, the soft margins asking more care than the footing.
