The reservoir was originally constructed to support water management needs for the surrounding forested terrain.
It is part of the broader Belgrad Forest region, which historically provided the primary water supply to Constantinople via Ottoman-era aqueducts.
The park serves as a migration stopover for various local bird species inhabiting the northern Istanbul wetlands.
The terrain is composed of clay-heavy soil common to the Black Sea climate influence of northern Istanbul.
The surrounding woods contain native species of Quercus frainetto, the Hungarian oak.
Göktürk Ponds National Park is a protected woodland area surrounding a large artificial reservoir in the northern outskirts of Eyüpsultan, Istanbul. The park spans a significant forested valley characterized by mature pine and oak trees, offering a distinct natural buffer from the nearby urban sprawl. It features a designated perimeter track around the pond that serves as a popular route for local trail runners and walkers. Several wooden piers extend into the water, providing vantage points across the reservoir. The site serves as a vital component of the Istanbul Belgrad Forest ecosystem complex. Picnic facilities and rudimentary outdoor seating are scattered throughout the wooded periphery. The park grounds are maintained by the Eyüpsultan Municipality and are specifically managed as a recreational nature reserve.

Wear footwear suitable for uneven, dirt-packed forest trails rather than paved paths.
Bring your own supplies, as on-site facilities are limited compared to urban city parks.
Visit during weekdays to avoid high weekend foot traffic from local residents.
Do not attempt to swim in the reservoir, as water quality is not monitored for recreational use and the banks are often muddy.
Strictly observe fire bans due to forest fire risks; carry out all trash to maintain the ecological integrity of the pond.
