Why anglers check water levels

Water level changes affect access, current, fish position and safety. A rising Danube, a falling Sava or clear Drina conditions can completely change the plan for a day on the water.

Haul stores public hydrological readings and displays them with attribution. Data is cached in our database and refreshed by scheduled jobs, so the map does not hit source websites on every user request.
