Lake Maggiore (UK: , US: ; Italian: Lago Maggiore Italian pronunciation: [ˈlaːɡo madˈdʒoːre]; Western Lombard: Lagh Maggior; Piedmontese: Lagh Magior; literally 'greater lake') or Verbano (pronounced [verˈbaːno]; Latin: Lacus Verbanus) is a large lake located on the south side of the Alps. It is the second largest lake in Italy and the largest in southern Switzerland. The lake and its shoreline are divided between the Italian regions of Piedmont and Lombardy and the Swiss canton of Ticino. Located halfway between Lake Orta and Lake Lugano, Lake Maggiore extends for about 64 kilometres (40 miles) between Locarno and Arona. The climate is mild in both summer and winter, producing Mediterranean vegetation, with many gardens growing rare and exotic plants. Well-known gardens include those of the Borromean and Brissago Islands, that of the Villa Taranto in Verbania, and the Alpinia Botanical Garden above Stresa. Lake Maggiore is drained by the river Ticino, a main tributary of the Po. Its basin also collects the waters of several large lakes, notably Lake Lugano (through the Tresa), Lake Orta (through the Toce) and Lake Varese (through the Bardello).

Delio Lake is a lake in the Province of Varese, Lombardy, Italy. At an elevation of 930 m, its surface area is about 30 ha (74 acres). It serves as the upper reservoir for the pumped-storage Roncovalgrande Hydroelectric Plant.

On 25 April 2010, the former municipalities of Caviano, Contone, Gerra Gambarogno, Indemini, Magadino, Piazzogna, San Nazzaro, Sant'Abbondio and Vira Gambarogno merged in the new municipality of Gambarogno.

Gambarogno is a municipality in the district of Locarno in the canton of Ticino in Switzerland. It was created on 25 April 2010 through the merger of the municipalities of Caviano, Contone, Gerra, Indemini, Magadino, Piazzogna, San Nazzaro, Sant'Abbondio and Vira.Gambarogno borders the following municipalities: Alto Malcantone, Ascona, Curiglia con Monteviasco (IT-VA), Locarno, Minusio, Monteceneri, Tenero-Contra, Maccagno con Pino e Veddasca (IT-VA).

The Roncovalgrande Hydroelectric Plant, also known as the Delio Hydroelectric Plant, is located 3 kilometres (1.9 mi) north of Maccagno in the Province of Varese, Lombardy, Italy. Using the pumped-storage hydroelectric method, the power plant has an installed capacity of 1,016 megawatts (1,362,000 hp). The power plant was complete in 1971 and the last generator operational in 1973. During construction, the upper reservoir, Lago Delio, was expanded in capacity with two gravity dams; a northern and southern, 28.5 metres (94 ft) and 36 metres (118 ft) in height, respectively. The lower reservoir, Lago Maggiore, already existed. The power plant itself is located underground in between Delio and Maggiore. To produce electricity, water is released from the upper reservoir to the power plant via two 1,100 metres (3,600 ft) long penstocks. At the power plant, eight four-stage Pelton turbine-generators generate electricity. Power generation occurs during periods of high energy demand and when energy demand is low, pumping usually occurs. The pumps are on the same shaft as the Pelton turbines and send water from the lower to the upper reservoir to serve as stored energy. Later on, this water will be sent back down to the power station and the process will repeat. The difference in elevation between the upper and lower reservoirs affords a hydraulic head of 736.25 m (2,416 ft) and Lago Delio has a usable storage capacity of 10,000,000 cubic metres (8,100 acre⋅ft).

The Brissago Islands (Italian: Isole di Brissago) are a group of two islands located in the Swiss part of Lake Maggiore close to Ronco sopra Ascona and Brissago. Both islands belong to the district of Locarno, in the canton of Ticino. San Pancrazio (also known as Grande Isola) is larger and is well known for its botanical garden. On the smaller island, known as Isolino, Isola Piccola or Isola di Sant’Apollinare, the vegetation is allowed to develop naturally. Both benefit from the mild climate provided by the lake. The minimum distance from the shore is 1,040 metres for San Pancrazio and 930 metres for Sant'Apollinare, making them the farthest islands from the shore in Switzerland. Both islands culminate at 200 metres above sea level or 7 metres above lake level (193 m).

Sant`Abbondio is a former municipality in the district of Locarno in the canton of Ticino in Switzerland. On 25 April 2010, the former municipalities of Caviano, Contone, Gerra Gambarogno, Indemini, Magadino, Piazzogna, San Nazzaro, Sant'Abbondio and Vira Gambarogno merged in the new municipality of Gambarogno.
