The ecology of freshwater bivalves in the Lake Sapanca basin, Turkey

“…The lake is used as a source of drinking water for the city and district of Sakarya and as a recreational amenity. Although Lake Sapanca water shows evidence of enrichment with nitrates and phosphates from trout farms, of which there are more than 30 in the vicinity of the lake, it has an oligotrophic character (Albay et al, 2003). Sampling stations around the lake and in associated rivers were chosen to be representative of the major habitat types in the lake.…”

“…Numan (1958), who carried out the first limnological study in Lake Sapanca, pointed out that the lake had an oligotrophic character. Although Lake Sapanca water is enriched by water from trout farms, which are common in this region, with more than thirty in the vicinity of the lake, it has still an oligotrophic character (Albay et al, 2003). Several streams and ground water entering from the bottom feed the lake.…”

“…Although Lake Sapanca water is enriched by water from trout farms, which are common in this region, with more than thirty in the vicinity of the lake, it has an oligotrophic character (Albay et al, 2003) and is one of the few lakes in Turkey, which provides drinking water, but it is exposed to heavy urbanization because of its natural beauty and its proximity to the metropolitan Istanbul. The lake is fed by surface and ground waters and is considered to have enough capacity to supply water for its surrounding settlements until the year 2030 (Tanık et al, 1998).…”
