Method I
Swanton Dam metal hatch
concrete block fixing dam
Missisquoi River
concrete wall
Figure 1 Swanton Dam - indicative scheme
We must built a semicircle and rectangular canals for fishes migration wich
must affixed by the concrete wall. This canal will cross through concrete block
fixing dam(figure 1). The semicircle or rectangular canals for fishes migration not
spoil-deteriorate the dam structure.

3. This canal will be inclined plane and will be fixing on the concrete wall(figure 3).

The fishes can run upstream and downstream inside the semicircle canal
without problems. About length for semicircle is ten meters and catchment basin
have one side 3 meters and the other side 4 meters. The ecotechnic solution help the
kayak sport and the ecosytem restoration and we give a normal price for this
construction.

5. Method II
You have the other sort of dam maybe, I suppose, upstream the Swanton Dam.
dam
metal canal
In this case you must fixing a metal box, metal canal (chute) and a catchment
basin (figure 1). YOU MUST SEE THE VII methods of my book and you must
respect all of this book for construction the fishes passages for this dam.
Thank you
