Resumo: This study deals with the taxonomic composition of the division Chlorophyta from Tartarugas Lake, an urban system located at the Botanical Garden, Porto Alegre, in Rio Grande do Sul State. Phytoplankton samples were collected monthly, from June 2007 to May 2008 in the pelagic zone. Sixty one specific and infraspecific taxa were described. Scenedesmaceae presented the highest richness (37.7%) preceded by Selenastraceae (34.4%). Desmodesmus and Monoraphidium was best represented (10 taxa each one). Chlorotetraedron incus (Teil.) Kom. & Kov., Desmodesmus armatus (Chodat) Hegewald var. armatus, Monactinus simplex (Meyen) Corda var. simplex, Monoraphidium contortum (Thur.) Komárková-Legnerová, M. convolutum (Corda) Komárková-Legnerová, M. minutum (Nägeli) Komárková-Legnerová, Pediastrum duplex Meyen var. rugulosum Raciborski and Stauridium tetras (Ehrenberg) Hegewald remained present throughout all seasons. Micractinium pusillum Fresenius was presented only during winter, when it was registered the lowest temperatures (13.6°C) were recorded. 17% of the taxa are new records to the artificial lake in Brazil.

Amostragens de fitoplâncton foram realizadas, mensalmente, em zona pelágica, no período de junho de 2007 a maio de 2008. São descritos 61 táxons específicos e infraespecíficos. Scenedesmaceae foi a família com maior riqueza específica (37,7%) precedida por Selenastraceae (34,4%). Desmodesmus e Monoraphidium foram os gêneros mais representativos (10 táxons cada). Chlorotetraedron incus (Teiling) Komárek & Kovácik, Desmodesmus armatus (Chodat) Hegewald var. armatus, Monactinus simplex (Meyen) Corda var. simplex, Monoraphidium contortum (Thuret) Komárkova-Legnerová, M. convolutum (Corda) Komárková-Legnerová e M. minutum (Nägeli) Komárková.-Legnerová, Pediastrum duplex var. rugulosum Raciborski e Stauridium tetras (Ehrenberg) Hegewald estiveram presentes ao longo das estações do ano. Micractinium pusillum Fresenius foi registrada apenas no inverno, período de temperaturas mais baixas (13,6°C). Um total de 17% dos táxons são primeiros registros para lagos artificiais no Brasil.Iheringia.
