+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: The
+	  getGauge() method returns the first gauge based on the given start and
+	  end point of the river.
+
+	* src/main/java/de/intevation/flys/artifacts/states/WQSelect.java:
+	  Fixed potential bugs: if no gauge could be determined, the default
+	  values for W and Q are the minimum and maximum double values.
