Base De Loisirs De Moisson

France Lake 1 - Excellent

The Boucles de Seine leisure base is a bathing water site managed by a partnership of four local authorities in Île-de-France. The water body is a gravel pit that functions as a recreational lake. Water quality is generally good according to the 1976 directive classification, though a pollution episode in 2004 caused a temporary downgrade, and an algal bloom resulted in bathing closure for two weeks in August 2012.

Water

The bathing area is a gravel pit lake (plan d'eau). It is fed by groundwater linked to the water body, runoff from the watershed, and occasional exceptional overflow from the Seine river.

Location

The Boucles de Seine leisure base is located in Île-de-France, involving the municipalities of Moisson and Mousseaux-sur-Seine in the Yvelines department.

Facilities

The site has camping accommodation and a golf course. Specific facilities such as lifeguards, toilets, showers, and disabled access are referenced in the document structure but details are not provided in the available text.

Water Quality

Water quality analysis shows the bathing zone is mostly of good quality according to the 1976 directive classification. An analysis according to the new 2006 directive would apply from the end of the 2013 season. A pollution episode in 2004 caused a temporary downgrade to momentarily polluted status. An algal bloom in August 2012 led to bathing closure for two weeks.

Risks

Potential pollution sources include agricultural runoff, fecal contamination from human and animal activity, bacterial germs, viruses and parasites, wastewater system malfunctions, internal water pollution, and algal blooms. Occasional exceptional flooding from the Seine is possible.
