Dive Site Characteristics
Dive Site Overview
Gasselterveld, also identified by local nicknames Jonkersgat or 't Nije Hemelriek, has transitioned into a well-regarded freshwater dive site within the Netherlands' Drenthe region. Historically, this site developed from a former sand extraction area, which significantly shaped its deep profile and sandy bottom.
Now, it serves as a prominent training ground for divers across various skill levels, from introductory courses to advanced deep diving certifications. Divers here often navigate a distinct line course, commencing just before the entry point and leading to various submerged objects like traffic signs and statues, offering a structured exploration route. While marine life may be limited compared to coral reefs, the site's clear water typically allows for good visibility, which averages between 3 to 7 m (10 to 23 ft), though reports vary widely from 0.2 m (0.7 ft) to 6 m (20 ft) in optimal conditions.
The maximum depth reaches 50 m (164 ft), accommodating those certified for deeper excursions, making it a versatile location.
Best Time to Dive
Diving conditions at Gasselterveld are most favorable during the warmer months, typically extending from May through September. Throughout this period, average air temperatures range from 13.8°C (56.8°F) in May to 17.9°C (64.2°F) in August, ensuring a more comfortable topside experience. Rainfall also tends to be moderate during these months, with averages around 1.7 to 4.7 mm (0.07 to 0.19 inches), which helps minimize surface run-off that could potentially impact underwater visibility. While specific average water temperatures aren't consistently reported, log entries suggest they can vary between 5°C (41°F) in colder periods to 17°C (63°F) during summer. For the best chance of clear water, aim for dives on days following a stable weather pattern, especially when heavy rain has been absent, as this reduces sediment disturbance.

Dive Experience & Conditions
Submerging into Gasselterveld, divers are immediately met with the unique sensation of freshwater diving. Water can feel quite cool, particularly in deeper sections, underscoring the need for appropriate thermal protection. A fine sandy bottom dominates the underwater landscape, interspersed with gentle gullies and hills that add to the topographical interest. Visibility often varies; on certain days, divers report exceptionally clear conditions, allowing views across several meters, while on others, especially after heavy usage or recent disturbance, it can reduce significantly, sometimes to only 20 cm (8 inches). Absence of current makes for a relaxed dive, allowing focus on buoyancy control and exploration of the line course. An established course, adorned with various objects, creates a structured underwater journey, ideal for practice and navigation. Maximum depth in this lake is considerable, though many recreational dives remain in shallower, more illuminated areas.
Dive Difficulty & Safety Guidelines
Approaching Gasselterveld requires adherence to specific protocols to ensure a safe and respectful dive. Always secure an access card in advance from the NNDF, displaying it clearly on your vehicle's windshield; diving without one is not permitted. When driving along the forest road to the water's edge, close the barrier after passing through it. Critically, avoid blocking the slipway at the entry point, ensuring clear access for all. Night diving is strictly forbidden, and diving on the east side is also prohibited due to concerns about unstable walls. This site is suitable for all levels, including free diving and deep diving, but inexperienced divers must remain within their training limits given the maximum depth. With no reported currents, primary safety considerations revolve around controlled entry and exit, maintaining proper buoyancy to avoid disturbing the fine sand, and respecting all posted site rules.
