Heavy monsoon rain tore out bridges in the lower valley, cut the route toward Larke (Larkya) Pass, and forced climbers headed to Manaslu Base Camp onto helicopters. Within 48 hours, local villagers had rebuilt a crossing and reopened an alternative path. So is the trek back on, and is it actually safe to go right now? Here's what's happened and what it means for anyone planning a trip this season.</p><h2>What just happened on the trail</h2><p>[ATTACH=full]1139[/ATTACH]</p><p>Before dawn on Sunday, September 6, sudden heavy rain caused the Therang Khola river to swell in the Namrung area, deep in the forested lower section of the route. The flood swept away four houses and both suspension bridges that link the valleys there, effectively cutting the Manaslu Circuit in two. With the crossings gone, local authorities urged trekkers heading toward Manaslu and Larke Pass to postpone their trips, and climbers already booked for Manaslu Base Camp were flown in by helicopter instead of walking in.</p><p></p><p>The closure didn't last long. Within a couple of days, residents of Chumanuwri Rural Municipality the area covering the lower Manaslu route built a temporary wooden bridge over the Therang River and cleared an old, disused path to reconnect with the main trail. Local authorities then declared the route open again. That's the "reopening" now making the rounds among trekking operators and forums.</p><p></p><p>It's worth being precise about what actually reopened. This isn't a rebuilt, engineered crossing it's a stopgap. The new bridge is a basic structure of logs and planks, thrown together quickly so locals could reach a neighboring valley, and by most accounts it would offer little resistance if the river rose again. Even with the trail passable, the safety advisory issued after the flash flood has not been lifted, and Gorkha district officials are still advising trekkers to hold off until conditions stabilize further.</p><h2>Why this happened now — and why it's not the Langtang disaster</h2><p>If you've seen alarming headlines about flooding in Nepal this season, it's worth separating two very different events. About two weeks before the Manaslu washout, a catastrophic glacial lake outburst flood (GLOF) devastated the Langtang and Bhote Koshi/Trishuli valleys near the Tibet border a different watershed entirely, roughly a day's drive from Manaslu.

Crucially, the major high-altitude trekking and climbing regions Khumbu/Everest, Manaslu, the Annapurna Circuit, Mustang, Dolpo, and Kangchenjunga sit in separate watersheds and were reported as unaffected and operating normally at that point, with large operators confirming their Manaslu-season programs were staying on schedule.</p><p></p><p>So the September 6 flooding in Namrung wasn't a repeat of the Langtang catastrophe.
