2. Rhine-west
sub basin
River basins in Europe

3. Rhine-West Regional Water Council
Rhine-West sub basin
water authorities:
• 2 ministries
• 4 provinces
• 8 water boards
• representatives of 170 municipalities

4. WFD: intensive multi-level cooperation ...
Dit is de kaart van het grondgebruik van rond 1970.
Let op de ligging van de zoet/zout grens, de grootschalige landbouw, kleinschalige landbouw, glastuinbouw, fruitteelt, de hoeveelheid aan regionale veilingen en waterwinningen voor drinkwater en industrie.
Op de volgende kaart is de zoet-zoutgrens verschoven naar het westen.

6. Rhine-West Regional Water Council
Main gateway, economically and ecologically
Habitat fragmentation: 520 barriers
Sharp decline in migratory fish stocks
Focus on opening up migration routes instead of lifting single barriers
Rhine-West successful joint approach: Roadmap for fish migration

7. Roadmap fish migration
Methods & Results:
In workshops making good use of local knowledge fish experts ALL water authorities
Analysis different individual fish migration approaches
Joint vision on fish migration (ecological role of region within the river basin)

8. Notice emphasis on SUCCESSES to the right, highlighting the EFFORT and TOGETHERNESS
Highlight: Fish Lift + NZK
Fish Lift: During springtime migratory fish are lifted into the polders through a tube in the dykes. When autumn arrives, outgoing fish are lifted back out of the area (innovation begin used throughout the delta river basin).
NZK: The Noordzeekanaal is a big canal and shipping route. Also a major route for migratory fish in the
Netherlands being one of the few open connections to the North Sea. Up until recently connections to side-channels were often blocked
off for migratory fish. Water authorities have joined together to successfully address these issues. Monitoring results show migratory fish (such as 3D stickleback and Eel) are benefitting in great numbers.

9. Roadmap fish migration
prioritizing method:
Detailed roadmap
Highways (blue)
Regional waters (red)
Local waters (yellow)
Top30 prioritiy measures (mainly at junctions highways and regional waters)

10. Roadmap fish migration research & monitoring:
Routes rather than individual measures
Quantitative effect Top30 measures on restoration of fish stocks, ie European Eel
Good ecological status is indicated by healthy fish stocks, particularly migratory fish like Eel

11. Pictures of successes in Rhine-west sub basin …
You may notice this presentation has (too) much emphasis on SUCCESSES. But this is intrinsic part of our method,
highlighting the JOINT EFFORT and TOGETHERNESS. Key to SUCCES with so many administrative levels and partners working together.
-Top left: You may recognize the Rotterdam bridge. Apart from being an economic route for vessels, the Nieuwe Waterweg canal at Rotterdam is also open a major connection between the North sea and the river Rhine upstream
– Bottom left: Haring vliet sluices (another connection that is going to be opened soon)

12. From Regional Roadmap to River Basin approach
Regional approach complements Masterplan ICPR
Making good use of regional fish expert knowledge
Dissemination of Rhine-West Roadmap method
Compare with other North Sea deltas
Joint Rhine River Basin Roadmap approach on regional, national, international level
Regional Roadmaps help to place the WFD on the political agenda / decision making at regional and national level
