“…Peaks of TP around 20 lg l -1 were recorded in 1999 and 2004, after deep mixing episodes (Salmaso et al, 2007). The situation is now stable, with a maximum TP concentration at overturn equal to 18 lg l -1 and an annual average equal to 13 lg l -1 (Salmaso et al, 2016).…”

For effective lakes' management, highfrequent water quality data on a synoptic scale are essential. The aim of this study is to test the suitability of the latest generation of satellite sensors to provide information on lake water quality parameters for the five largest Italian subalpine lakes. In situ data of phytoplankton composition, chlorophyll-a (chl-a) concentration and water reflectance were used in synergy with satellite observations to map some algal blooms in 2016. Chl-a concentration maps were derived from satellite data by applying a bio-optical model to satellite data, previously corrected for atmospheric effects. Results were compared with in situ data, showing good agreement. The shape and magnitude of water reflectance from different satellite data were consistent. Output chl-a concentration maps, show the distribution within each lake during blooming events, suggesting a synoptic view is required for these events monitoring. Maps show the dynamic of bloom events with concentration increasing from 2 up to 7 mg m -3 and dropping again to initial value in less than 20 days. Latest generation sensors were shown to be valuable tools for lakes monitoring, thanks to frequent, free of charge data availability over long time periods.

“…It has a maximum depth of 370 m and an average depth of 178 m, as reported in Salmaso et al (2007). It is oligotrophic by nature, as shown by early limnological studies (Baldi 1949) and by analysis of the sedimentary pigments (Guilizzoni et al 1983).…”

“…In fact, the combination of absorbing material and suspended particles in high concentration would decrease the penetration of sunlight in the water column (Wetzel, 2001;Salmaso et al, 2007). Our correlation analysis, using lake data sets for which both parameters were available, suggested that the Secchi depth can be useful to distinguish between lakes having DOC values varying in different ranges.…”

“…This relationship was applied to the Iseo samples, whenever the DOC was not available (for a total of n = 85 data points), and also to the Garda samples (n = 126), to get an estimate of the DOC values and their variations. The application of this relationship to Lake Garda and Lake Iseo is justifiable because of the common limnological and morphometrical (Table S1) features of the two water bodies, as well as of the common geological composition of the watersheds (Salmaso et al, 2007).…”
