Hod HaSharon park, Urban park in Hod HaSharon, Israel

Hod HaSharon park is a large green space in the city that centers around an artificial lake surrounded by planted areas. Connected pathways link different zones where visitors can walk, cycle, or stop to observe the water and surrounding plantings.

The hill at the park's centre served as Hod HaSharon's municipal landfill until the mid-1990s. South of the Green Basins, the historic mouth of Nahal Kana met Nahal Hadar until the 1950s, when Nahal Kana was diverted east to prevent flooding of farmland. The bridge over that old channel, built in the 1930s for carts carrying fruit crates, now carries the Israel National Trail.

The lake's water comes from the Kfar Saba–Hod HaSharon sewage treatment plant and is polished in the "Green Basins", gravel beds planted with water plants that filter it biologically before it flows down Nahal Hadar to the Yarkon from May 2014. The water is not meant for bathing. Willows at the old Nahal Kana junction mark high groundwater.

A winding dirt track climbs the hill from the west; it is open to off-road vehicles and bicycles but closed to private cars. The Israel National Trail crosses the bridge at the mouth of Nahal Hadar, where it meets the Yarkon. The lake water is treated effluent and is not meant for bathing.

The lake holds 27 dunams of treated wastewater from the Kfar Saba–Hod HaSharon sewage treatment plant. Since May 2014 this water has flowed down Nahal Hadar into the Yarkon, improving the river's volume and quality. Soft-shell turtles and coypu have been seen in the water.
