A walking track around the lower reservoir that supplies Marton's water will have its official opening on October 10.
Speakers will be Rangitīkei mayor Andy Watson and Tutaenui Stream Restoration Society's Greg Carlyon.
After the formalities, people will have a chance to step out on the gravel paths of the 4km Kōtare Track around the lower dam. There is also a shorter loop walk, information kiosk and picnic area.
A sausage sizzle is planned for noon.
The opening is just one milestone in nearly 10 years' work to convert the 70ha around the two dams that supply Marton's water into Tutaenui Nature Reserve - with more walking tracks, restored native bush, predator and weed control and many more birds.
