Some figures:

• 1300 Waterbodies, 40 types, still under discussion

• Only very few natural waters• Most waters thought to be at risk in 2015• Lakes, rivers, transitional waters and

coast• Managed by 37 watermanagers (27+ 10)• Divided in 4 catchment areas : Rhine,

Meuse, Scheldt and Eems

Monitoring

• Guidelines ready for ecology and chemical substances

• Discussion on number of waterbodies to be monitored for ecology

• Most of the watermanagers are already monitoring chemicals

• In particular fish monitoring new to many watermanagers

• Minimum frequency has been chosen

Example: Points of discussion for Biological Monitoring

• Artificial en Heavily modified : what will be the objectives?

• How to aggregate waterbodies? • How to deal with protected area’s and

Groundwater bodies? Which objectives are leading?

• Cost efficiency, what is reasonable?• Quality of measurements and statistics
