The blue river network is overprinted with coded fish populations, their relative abundance, average river width and depth and Léger’s “capacité biogénique” productivity index. Further symbols identify lakes and reservoirs, spawning grounds, fishing reserves, dams, fish ladders, hydroelectric works, fish farms, angling societies and damaging industrial discharges. Relief and departmental boundaries place the data around Gap, Briançon, Embrun, the Durance, Drac and high Alpine lakes. A striking early scientific and environmental map, issued with Léger’s explanatory study.\u003c\/em\u003e\u003c\/p\u003e","brand":"Antiquemapsandprints.com","offers":[{"title":"Default Title","offer_id":53896239612251,"sku":"P-6-112321","price":160.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/9583\/1643\/files\/P-6-112321a.jpg?v=1787833512"}],"url":"https:\/\/www.antiquemapsandprints.com\/collections\/leger-louis.oembed","provider":"Antiquemapsandprints.com","version":"1.0","type":"link"}
