2. Geographic situation
3. Source BRGM Cartography DIREN/BRGM Geomorphology and Geology Area : 8,680 km2 (3,351 sq mi) Length : 184 km (114.3 mi) Width : 83 km (51.6 mi) Coastline :1,000 km (600 mi) Highest Elevation : 2,706 m (8,878 ft) Corsicais made of severalgeologicdistinct zones: The CrystallineCorsica (with granit, gneiss and volcanic rock) covers the most important part of the island The Alpine Corsica (withshists and limestone) The Central Furrow (secondary and tertiarysediments) The CalcareousCorsica
4. General description POPULATION (source INSEE) : 303,000 inhabitants (2008). Population older than the national average. Today Corsica is more urban than rural, even if rural areas represent 80 % of the territory. Total active population : 100,772. Unemployment rate : 9 % (2010) Unequalrepartition of the population : concentration on coastalregions and around major roads. Onthe contrary, the villages of the interior are abandoned. Averagedensity : 35 inh/km2 Touristic population very important mainly in summer : 3 million in summer 2009. Approximatively 10 tourists per inhabitant.
5. TOURISM : INDUSTRY : AGRICULTURE : General description One of the main engine of the insulareconomywith9.5 % of the island’s GDP and 12 % of the total employment. (GDP/nominal : € 7 billion. GDP/nominal: € 20,300 million) Numberof touristincreasedrapidly : 3 million in 2009, 2.3 million in summer 2003. The touristicseasongoesfrom May to October (mainlyseasideactivity). Industry represents 13.6 % of the GDP and 6.5 % of total employment. Main activity : hydropower production, electricity (Total power : 524 MW). The agricultural sector represents 2.4 % of the GDP and 4 % of the total employment. Main productions : - Orchards (citrus trees, kiwi, plum, chestnut, almond,olive) - Vine growing Cereals Breeding 11% Citrus tree 29% Kiwi 23% Chestnut Almond Olive Other 12% 10% 15%

7. Water uses The most important part of the water supply is ensured by surface water (dams and reserves storing water from rivers and rainfall). This water is used for irrigation, domestic uses and industry (energy production). Water consumption per activity sectors : - Domestic : 30 million m3(60 % GW, 40 % SW) - Agriculture : 30 million m3 (100 % SW) - Industry : 1 million m3 (100 % SW)
8. Situation of Corsica The Law of 22 january 2002 has entailedsignificant changes. Corsicaconstitutes an hydrographical Basin and possessesitsownBasin Committeewhichiscomposed by 36 members (3 groupes : Local Government (CTC), users, socio-professionals). The Basin committee has elaborated the corsicanSDAGE (water management framework) itwasadoptedin July 2009 and the CTC approvedit in Oct 2009. The corsican Basin isstilldepending on the Rhône-Méditerranée & Corse Water Agency (RMC). The missions of the Basin are ensured by CTC or by the State, the Prefect and his services.

9. Dams and reservesbelonging to HydraulicAgency of Corsica (OEHC) and EDF. Installations for the water supply in Corsica Hard water network. The water comesfroms the dams of the OEHC and EDF. This water isdestinated to severalaims : - Energy production (EDF) - Irrigation (OEHC) - Domestic uses (OEHC) aftertreatment Surface equipped for irrigation (managed by OEHC) Pumping plants (for the drinking water production) Water Management Description of the distribution network : Source « Convention on Water », OEHC 2003

Bastia Ajaccio Porto - Vecchio Dams and Reservoirs The artificial water reserves can have 3 kinds of uses: Production of hydroelecticity (E) Irrigation (I) Drinking water supply (AEP) EDF Dams Mobilization of the resource: 65 millions of m3 of water stored 6 dams 6 « collinaire » reserves 20 points of draw-off in rivers Distribution: 53 stations of pumping 200 Km of drain 30 stations of treatment Dams and reserves of OEHC (Corsican Hydraulic Equipment Agency)

12. Water Management by the Municipalities Water Management In RMC basin : 45 % of Delegated Management Price of water depends on way of management - Averageprice in Corsica in 2007 : 3.34 €/m3 (2.89 € for the RMC Basin) The pricewas 1.72 € in 1992
