This equipment integrate canoes, inflatable boats, pedal boats, etc ...
Beach gear cannot go further than 100 meters from the shore, they must remain within the latter when it is materialized by a line of buoys (spherical yellow buoys of 600 mm diameter) .

What is tidal range?
The tidal range is the difference in level encountered by the lake of Serre-Ponçon between its filling nominal coast (set at 780 meters GLF) and the level of the destocking. This destocking, managed by EDF, can be the result of the hydroelectric exploitation of the reservoir and the supply of drinking, industrial and agricultural water of Provence. By agreement signed in June 2008 between EDF and SMADESEP, the concessioner of the reservoir is committed to ensure not to exceed 5 meters of tidal range between the 1st of July  and the 31st of August , so that it doesn’t go below the coast  of 755 meters NGF considered as the minimum coast for tourist exploitation.

How to prevent water pollution?
I prefer heavy bags or baskets rather than too light bag that can fly away; I carefully fill the fuel tank of my boat, preferably on the dock, and by using a sufficiently large funnel to avoid spilling fuel in the water. On my boat, I use water without detergent, I throw my garbage in spaces reserved for this purpose at land, I prefer, when the size of the boat allows, the mechanical cleaning of boats hulls (manual scraping, sanding ... ) rather than the application of antifouling paints. They contain biocides which may have an impact on the environment. If the size of the boat requires the use of these paintings, please follow the application rates and limit the discharges into the environment (ex: use of tarpaulins to recover the projections of paintings), I use preferably a LPG motor, an electric or four-stroke engine rather than a two-stroke engine for my outboard motor boat. Fuel consumption will be reduced as well as the gaseous and noise emissions.

How to respect the fauna and flora?
I respect the natural environment by avoiding the degradation of sensitive areas, nesting and breeding areas of local fauna: reed beds, banks, small islands, rivers.
I respect the imposed speed limitations around the banks and I keep a reasonable distance to reduce the wake and the too large eddies which result in bank erosion and damage to the vegetation.

How to act to reduce the environmental impact?
I collect the plastic bags floating in the water, I respect the minimum catch sizes and authorized materials, in catching fish below the size limits, I prevent the natural regeneration of species and I reduce the resources.
