Formed by one of the world's tallest dams, Tehri Lake has grown from an engineering project into Uttarakhand's biggest water-sports destination.
Tehri Lake exists because of the Tehri Dam — at 260.5 metres, one of the tallest dams in the world — but the reservoir it created has since become an attraction entirely in its own right, drawing visitors less for the engineering and more for what's now a full water-sports economy built around its unusually deep, clear water.
Jet skiing, kayaking, banana boat rides, and speed boating are all commercially operated on the lake, largely concentrated around the New Tehri and Koti Colony areas where operators have set up dedicated launch points. The Tehri Lake Festival, typically held in winter, has become the region's flagship promotional event for these activities, drawing operators, competitions, and a noticeably bigger crowd than the lake sees on an average weekend outside festival dates.
One of the more distinctive recent additions to the lake is a set of floating cottages/huts moored on the water, offering an overnight stay directly on the reservoir rather than at a conventional lakeside hotel — a genuinely novel experience for Uttarakhand, though capacity is limited and advance booking is essential given how few units exist relative to demand.
New Tehri, built on higher ground after the original Tehri town was submerged by the reservoir, sits above the lake and offers panoramic views down over the water — worth a stop for the view alone, and a useful base for arranging lake activities if floating-hut accommodation isn't available or preferred.
October to March offers the most comfortable weather for water sports, with clear skies and manageable temperatures for time spent on or near the water. Summer (April-June) is also active for water sports despite the heat, since the lake itself offers a cooling escape from plains temperatures. Monsoon months see reduced water-sports operations and are generally the least recommended window given both weather risk and lower water clarity from runoff.
Most water-sports operators run on a walk-in, pay-per-activity basis at their lakeside setups rather than requiring advance booking, though weekends and festival dates see longer waits and it's worth arriving earlier in the day for the widest choice of activities and shorter queues. Prices vary by operator and activity, generally running from a few hundred rupees for shorter rides to more for extended jet-ski or speed-boat sessions — checking current rates and safety equipment (life jackets, in particular) with the specific operator before paying is sensible practice at any unregulated lakeside setup.
Tehri Lake is genuinely deep in parts given its origin as a dam reservoir, and swimming outside designated, supervised areas isn't advisable regardless of swimming ability. Sticking to operators who provide proper life jackets and visible safety oversight — rather than the cheapest option available — is the sensible approach for any water activity here.
Is Tehri Lake suitable for a day trip from Dehradun? Yes, the roughly 2.5-3 hour drive each way makes it a genuinely workable day trip, though an overnight stay (including the floating huts, if available) allows a more relaxed visit.
Do I need to book water sports activities in advance? Generally no for standard activities, though weekends and the Tehri Lake Festival period see longer waits, and booking ahead specifically for the floating-hut stays is essential given limited capacity.
Is Tehri Lake safe for children? Water sports activities suited to children (like calmer boat rides) are available, but given the lake's depth, close supervision and proper life jackets are non-negotiable regardless of the specific activity chosen.
What's the best month for the Tehri Lake Festival? It's typically held in winter (check current-year dates, as they shift slightly year to year) and represents the busiest, most activity-packed period at the lake.
