Concerns for Finow Canal

Posted on by

We are unequivocally supporting the efforts by the association Unser Finowkanal to secure the future of this important heritage waterway, bypassed by the modern Havel-Oder Waterway.

The Federal Government has declared its intention to close the canal for navigation, convert the locks into weirs and maintain the channel exclusively for drainage.

The only way to avoid this scenario is to secure funding for the considerable investment of €75 million, to cover all costs, particularly to restore the locks. To date, all the locks have been operated each season, using unemployed from the local job centre (and two voluntary lock-keepers), but some repairs have become too urgent, and there is at present no authority nor any funding in place to implement them.

A boat rally celebrates the opening of the Finow Canal for the 2015 season. The association Unser Finowkanal continues its campaign for maintenance and regular operation of the canal, which the Federal waterway authority wishes to hand over to the region.

If one of the 12 historic locks fails, the canal will no longer be available as a through route, and the direct and indirect economic benefits of waterway tourism will be lost to the Eberswalde/Niederfinow region.

The municipalities of the Finowkanal region are under pressure to make a decision by January 2016, for or against their share in the necessary investment, and the issue is being firecely debated. On December 17, the Eberswalde council – with the biggest share in the project – will cast its vote. Only if all the local councils vote in favour of the canal investment will it become feasible to set up a public body to take over operation of the canal.

Investors need to be certain that the future of the canal is guaranteed, Under Federal government ownership, there are no opportunities for commercial activities at the locks or along the banks, volunteer lock-keepers are refused, and the risk of failure of the locks continues to hamper any development.

But regional decision-makers are procrastinating, and most of the officials in the Finow Canal regional working group are keeping a low profile, for fear of being held responsible for the failure to take over the canal.

Some councils are leaning towards rejection of the takeover because of the lack of evidence of the benefits that tourism could bring to the region, justifying their entrenched resistance to change.

Unser Finowkanal president Hartmut Ginnow-Merkert has made a plea for support: if you feel it is important to maintain continuous navigability of the Finow canal, comment here!

Water conveyors and waterways in Lombardy

A sense of urgency permeates the air in Lombardy as well as in neighbouring Piedmont, Emilia Romagna and Veneto regions, regarding Italy’s network of navigable canals and rivers. What reality will be revealed to the world of inland waterway specialists and advocates, meeting in Milan on September 1st for the 27th World Canals Conference? It is a reality of water conveyors and waterways, in places going their separate ways, but often combined within the same bed. Waterway cross-roads, intakes, siphons, spillways, aqueducts are the nodes of an intricate network spun across the Lombardy plain, and nothing is simple. Even Italy’s second biggest Alpine lake, Lago Maggiore, is used as a reservoir and drawn down by as much as 1.50m to secure irrigation water supplies during a dry summer.

Article in La Stampa

The ambitious project to restore navigation between Lago Maggiore (Locarno) and the river Po is regularly covered by the regional and national Press. This article focuses on work to start soon on a new lock at Porto della Torre, on the Piedmont bank of the Ticino

It is nearly 20 years since IWI’s founders attended a conference in Milan on the ‘civilisation of water and waterways’ and the heritage left by Leonardo da Vinci and other great Italian engineers. At that time a grouping of Rotary clubs in the Adda valley was actively promoting restoration of the locks on the Adda as well as the Naviglio di Paderno (followed by the Martesana towards Milan). The campaign sadly lost momentum after the president Mario Roveda died of a heart attack in 1997, but IWI, represented in Italy by industrial archeology expert Edo Bricchetti, has constantly been supporting the regional initiatives in favour of a navigable system serving ‘slow’ tourism and appreciation of the extraordinary heritage and environment of the canal corridors.

Navigli Lombardi was founded to drive these efforts, but does not manage the canals themselves; that is the prerogative of the Consorzio Villoresi, which has the concession from the Region to manage the water resource and supply the many needs of agriculture, industry and the population. This means that the ‘water conveyor’ function has priority here, in the same way as it has priority on another famous southern European canal, the Canal de Castilla in Spain.

Despite this priority, politicians in Milan and across the plain, including the neighbouring regions, are massively in favour of restoring and adapting the 1000-year legacy of canals and controlled rivers, to make navigation once again a regular form of mobility in both urban and rural areas.

Turbigo spillway

This spillway in Turbigo is only one part of a complex junction between the ‘industrial canal’ and the Naviglio Grande

Achieving this goal means compromises and concessions. As climate change increases the pressure on water resources, it is likely to become increasingly difficult to obtain management of water channels that is compatible with navigability, even by professional helmsmen. Another difficulty faced by all players in Lombardy is a certain degree of confusion in the minds of Milanese citizens, possibly even some planners and architects, between water conveyors and waterways. This is only the briefest of introductions to a fascinating story that will be told here in the coming days and weeks… background notes for the discussions during the World Canals Conference and the pre- and post-conference tours.

Move for restoration of Locarno-Milan waterway

Claudio Repossi of Navigli Lombardi reports on a series of events to raise awareness of the historic, cultural and recreational values of the Locarno (Switzerland) to Milan waterway via the river Ticino.

As part of the joint Italian-Swiss project Intrecci sull’acqua – or Dialogue on the Water – a series of initiatives have been launched, including guided tours of the area and pleasure boating on Lago Maggiore (Verbano), along what is known as the ancient ‘Marble Route’.
(supplying marble for the construction of Milan’s cathedral).

Events planned for the weekends of July, August and September were organised thanks to an agreement between the municipalities involved, the Lombardy Region, the Province of Novara and Navigli Lombardi, the last of which has been active for years with its passenger boat service on the Ticino running between Sesto Calende and the Miorina Barrage (and former lock).

The project includes navigation on the Ticino and on the Lake, partially covering the route taken of old by the barges that carried the precious construction material along the lake-river-canal waterway to Milan.

Today the former waterway is no longer navigable throughout, but great efforts are being made, at a time of crisis in public finances, to reopen it. Miorina lock on the Ticino has recently been restored to working order, and the Panperduto dam, machine hall and adjacent lock are also being rehabilitated. Begun in 2011, the works are financed by Lombardy Region, Consorzio Villoresi, Navigli Lombardi and the electricity utility ENEL, and are to be completed in 2013. Piedmont Region for its part is gathering the funds necessary for the restoration of the Porto della Torre barrage.

Once the works to restore the hydraulic structures on the Ticino are finished, it will be possible to navigate from Lago Maggiore to the start of the Industrial Canal, with four locks to restore as the last obstacle before the final link-up with the Naviglio Grande and Milan.  The Naviglio Grande is already navigable from Turbigo to Cuggiono, albeit with some size limits.

With Expo 2015 in view, an accord for an integrated plan for maintenance of the infrastructure of Milan’s canals and for the valorization of the Navigli and Lombardy waterways as an asset to tourism, the environment and culture, was promoted in May this year by the Lombardy Region, Consorzio Villoresi and Navigli Lombardi. Also involved are the Park management bodies for the Adda Nord Park, the Ticino Park, and the South Milan Agricultural Park. The programme, requiring an investment of around €20million for works to be carried out by June 2015, proposes substantial repairs to the banks of the Naviglio Grande and Naviglio Martesana. It has among its primary objectives the promotion of a Leonardo da Vinci cultural tourism trail along the Lombardy waterways where he experimented successfully with some of the most brilliant hydraulic inventions: the lock flight, the Da Vinci lock and its characteristic stepped upper sill. It also aims to promote the ‘Feed the Planet’ programme, principal theme of the 2015 Milan Expo.

Classifying recreational waterways by navigable draught

Posted on by

There is much concern in many parts of Europe, and especially on the secondary waterways in France, about maintenance of canal banks and the related issue of dredging. As author of the European Waterways Map & Directory, I adopted for that overview map the classification proposed by PIANC in 1999. This was later endorsed as UNECE Resolution No. 52, at the initiative of several organisations, including the European Boating Association. This classification focuses on boat size overall, i.e.
RC – motor yachts 15m long, 4m beam, 3.75m air draught and 1.50 m draught
RB – cabin cruisers and small yachts  9.50m long, 3m beam, 2.50m air draught and 1m draught
(RD is for standing mast routes, while RA is for light craft such as rafts and inflatables.)

Because of the sensitivity of dredging, I have adopted a different approach to categorising waterways in the new Imray map we have just completed. I know Inland Waterways of France is misleading by giving the ‘official’ draught, and one member of sister organisation DBA The Barge Association wrote to me about cruising on the Canal de la Robine as being closer to agriculture than navigation!

We are now proposing the following legend for this new French map.

So the thickest line corresponds to high-capacity waterways, generally offering a draught of at least 2 m. Then comes the commercial Class I or ‘Freycinet’ waterways, offering 1.80m in principle. The third category is recreational waterways offering a draught in the range of 1.40-1.60m, while a thin line without dark edges corresponds to waterways where the design draught is 1.00-1.30m.
And we place the clear caveat: Caution: these dimensions (headroom and draught) may not always be available. I believe we cannot be too literal in plotting all the anomalies throughout the network, that’s not the job of a simple overview planning map.
