  abstract = {{T}he supply of drinking water is a vital challenge for the people who live on the {A}frican continent, as this continent is experiencing strong demographic growth and therefore increasing water demands. {T}o meet these needs, surface water resources are becoming increasingly mobilized because underground resources are not always available or have already been overexploited. {T}his situation is the case in the region of {A}bidjan in the {I}vory {C}oast, where the drinking water deficit is a growing problem and it is therefore necessary to mobilize new water resources to ensure the supply of drinking water. {A}mong the potential resources, local managers have identified a freshwater lagoon, {L}agoon {A}ghien, {T}hat is in close proximity to the city of {A}bidjan. {W}ith the aim of enhancing knowledge on the ecological functioning of the lagoon and contributing to the assessment of its ability to provide drinking water, several physical and chemical parameters of the water and the phytoplankton community of the lagoon were monitored for 17 months ({D}ecember 2016-{A}pril 2018) at six sampling stations. {O}ur findings show that the lagoon is eutrophic, as evidenced by the high concentrations of total phosphorus (>140 mu g {L}-1), nitrogen (1.36 mg {L}-1) and average chlorophyll-a (26 to 167 mu g {L}-1) concentrations. {T}he phytoplankton community in the lagoon is dominated by genera typical of eutrophic environments including mixotrophic genera such as {P}eridinium and by cyanobacteria such as {C}ylindrospermopsis/{R}aphidiopsis, {M}icrocystis and {D}olichospermum that can potentially produce cyanotoxins. {T}he two rainfall peaks that occur in {J}une and {O}ctober appeared to be major events in terms of nutrient flows entering the lagoon, and the dynamics of these flows are complex. {S}ignificant differences were also found in the nutrient concentrations and to a lesser extent in the phytoplankton communities among the different stations, especially during the rainfall peaks. {O}verall, these results reveal that the quality of the lagoon's water is already severely degraded, and this degradation could increase in future years due to increasing urbanization in the watershed. {T}hese results therefore raise questions about the potential use of the lagoon as a source of drinking water if measures are not taken very quickly to protect this lagoon from increasing eutrophication and other pollution sources.},
