+    Work on flys/issue69
+
+    * src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
+      Use new logic to calculate "Wasserstand/Wasserspiegellage".
+      Compared to desktop FLYS are the results are structurally right 
+      but a bit off in the positions after the decimal points.
+      Maybe a result of the interpolation? Need to debug this.
