Gediz River in the context of "Ionia"

The Gediz Delta is the river delta at the confluence of the Gediz River with the Gulf of İzmir, in İzmir Province in western Turkey. It is a 14,900 ha area of land that occupies coastal parts of Foça, Menemen, and Çiğli districts. It is one of the largest areas of coastal wetlands in Turkeyand has a biodiversity of plants and birds. It is a Ramsar site since 1998 and an Important Bird Area since 2000. It is 26 km from İzmir city center.

In Greek mythology, Hermus or Hermos (Ancient Greek: Ἕρμος) is a name attributed to multiple characters:

• Hermus, god of the river Hermus (modern Gediz river) located in the Aegean region of Lydia (modern Turkey). Like most of the river-gods, he was the son of Oceanus and Tethys. Hermus was the father of the Lydian nymphs.
• Hermus, an Egyptian prince as one of the sons of King Aegyptus. His mother was the naiad Caliadne and thus full brother of Eurylochus, Phantes, Peristhenes, Dryas, Potamon, Cisseus, Lixus, Imbrus, Bromius, Polyctor and Chthonius. In some accounts, he could be a son of Aegyptus either by Eurryroe, daughter of the river-god Nilus, or Isaie, daughter of King Agenor of Tyre. Hermus suffered the same fate as his other brothers, save Lynceus, when they were slain on their wedding night by their wives who obeyed the command of their father King Danaus of Libya. He married the Danaid Cleopatra, daughter of Danaus and the naiad Polyxo.
• Hermus, a nobleman of Athens and a companion of Theseus. When Theseus founded the city of Pythopolis, he left Hermus there. A place in Pythopolis called the House of Hermes was named after him, incorrectly changing the name to that of a god.

Menemen (Turkish: [meneˈmæn]) is a municipality and district of İzmir Province, Turkey. Its area is 573 km, and its population is 200,904 (2022). The district extends on a fertile plain formed by the alluvial soil carried by the Gediz River. Adjacent districts are, from east to west; Aliağa and Foça to the north and Bornova, Karşıyaka and Çiğli to the south. Menemen district has a 27 km (17 mi) long coastline in the west and neighbors Manisa Province to the east. The town of Menemen is located at a distance of 35 km (22 mi) from İzmir center (Konak Square). Settlement across the district is loosely scattered along the Greater Metropolitan Area of İzmir in the south and consists of isolated villages along prairies in the north, which results in an average urbanization rate of only 42 per cent. The economy still relies on agriculture and stock breeding in large part, although the production and export of leather, ceramic and other earthenware products, as well as potentially of plastic products, based in two separate and specialized organized industrial zones made important steps forward during the last decade. Menemen's earthenware pottery products have been famous across Turkey for centuries. These two organized industrial zones as well as activities rebounding from the adjacent İzmir metropolitan area gain an increasing importance in the district's economy. Nevertheless, Gediz River, whose lower basin crosses Menemen plain to join the sea within the district boundaries still constitutes the lifeline of the region and matters relating to the river's flow as well as its present rate of rather high pollution is a matter of constant debate.

Çiğli Turkish: [ˈtʃiːli] is a municipality and district of İzmir Province, Turkey. Its area is 139 km, and its population is 214,065 (2022). It covers the northwestern part of the agglomeration of İzmir, around the mouth of the river Gediz, across the Gulf of İzmir from the main city. The Gediz delta is an Important Bird Area but is under threat from urbanization. IAOIZ, the İzmir Atatürk Organized Industrial Zone, is a significant economic hub and there is a major air force base.

Lake Marmara (Turkish: Marmara Gölü) is a lake in Manisa Province, western Turkey, bordered by the district areas of Gölmarmara to the northwest, whose name itself is inspired by the lake, and in larger part by Salihli.

Lake Marmara is located in the alluvial valley of the Gediz River and at 79 m (259 ft), is slightly lower than the surrounding plains of the river (91 m (299 ft) for the nearby Gölmarmara town center).

The Pactolus (Greek: Πακτωλός), also called Chrysorrhoas (Χρυσορρόας), the modern Sart Çayı or "'Sardis stream'", is a river near the Aegean coast of Turkey. The river rises from Mount Tmolus, flows through the ruins of the ancient city of Sardis, and empties into the Gediz River, the ancient Hermus.

The Pactolus once contained electrum, which was the basis of the economy of the ancient state of Lydia, where the naturally occurring alloy of gold and silver was used to mint the first coins under Alyattes of Lydia.

Gölmarmara is a municipality and district of Manisa Province, Turkey. Its area is 310 km, and its population is 15,193 (2022). It lies at a distance of 66 km (41 mi) from the province center of Manisa. The town owes its name to the nearby Lake Marmara, called under various names throughout history. The town of Gölmarmara itself was a mere village in Ottoman times cited under such names as "Marmaracık" or "Mermere". It was made into a township with its own municipality depending the district center of Akhisar at the time of the foundation of the Turkish Republic (1923) and in 1987 a district center by its own right and under the same name, Gölmarmara. Gölmarmara lies at an elevation of 91 m (299 ft).

Agricultural lands and forest lands each occupy roughly around 11,500 hectares in the district area, with a few thousand in the fertile plain of the Gediz River valley remaining unused. Lake Marmara, aside from being a recreational center for the province as a whole, is also an important source for fishing and agricultural irrigation. Slightly lower than the town center at 79 m (259 ft), the lake is also an Important Bird Area.
