**Deck**: Russian sabotage and reconnaissance groups are exploiting the dried-up bed of the Kakhovka Reservoir and a chain of riverside settlements to infiltrate Ukrainian positions near Stepnohirsk in Zaporizhzhia region. The quiet, small-unit incursions turn former waterlines into pathways for pressure on an already stretched southern front.

Russian forces are turning the scars of last year’s dam destruction into new attack routes, using the dried bed of the Kakhovka Reservoir and dense riverside settlements to infiltrate Ukrainian-held areas in Zaporizhzhia region. Reports from the Stepnohirsk direction say Russian diversionary reconnaissance groups, or DRGs, have been detected in the central part of Prymorske after likely moving through an almost continuous chain of residential areas from Plavni.

The activity, observed on 5 September and highlighted in fresh reporting on 8 September, suggests that Moscow is leaning on small, mobile units to probe and destabilize Ukrainian lines rather than relying solely on larger mechanized pushes. DRGs typically operate in small teams, scouting defensive positions, directing artillery fire, and seeking opportunities to stage raids or sabotage.

In this case, geography has become a force multiplier. The bed of the once-massive Kakhovka Reservoir — now largely drained after the destruction of the Kakhovka Dam — provides a broad, uneven corridor where trees and bushes have grown over the last year. Those thickets offer concealment for infiltrators moving under cover of darkness or poor weather, complicating detection by drones and ground observers.

For Ukrainian troops manning defenses near Stepnohirsk and along the Dnipro’s left-bank approaches, the threat is up close and personal. An enemy reconnaissance group that slips through can map trenches, identify weak points, and even attempt small assaults on outposts or logistics hubs. That forces Ukraine to allocate scarce infantry, night-vision gear and surveillance drones to rear and flank security rather than concentrating everything on the primary contact line.

Civilians in villages like Prymorske and Plavni, and in other settlements dotted along the former shoreline, are caught in a gray zone between front and rear. Infiltrations can bring sudden firefights, searches and counter-infiltration sweeps into areas that might otherwise see only sporadic shelling. The once-familiar landscape of riverbank towns and lakeside fields has been transformed into a patchwork of dry channels and overgrowth that favors those willing to take risks.

Strategically, the use of the dried reservoir bed underscores how both sides are adapting to the environmental and tactical consequences of the dam’s destruction. What was initially viewed mainly as a humanitarian and ecological disaster is now also shaping the geometry of combat operations. For Russia, the reservoir floor offers a way to bypass more heavily monitored roads and approach Ukrainian positions from unexpected angles.

For Ukraine, the challenge is to turn that same terrain into a monitored no-man’s land rather than an open door. That means integrating more sensors, patrols and defensive works across a wider area than traditional linear fronts demand. Stretching already thin manpower and equipment over these three-dimensional threats — from the air, across open steppe, and now through the thicketed reservoir bed — raises the risk that gaps will appear.

This kind of infiltration warfare rarely produces dramatic map changes overnight, but it can wear down defenders and set the conditions for larger offensives. A well-placed DRG can identify a soft seam, knock out a key observation post, or quietly correct artillery fire onto logistics sites, making future breakthroughs easier.

The next signs to watch will be whether reports of DRG activity along the former Kakhovka shoreline increase, whether Ukraine reinforces the Stepnohirsk sector with additional reconnaissance assets, and if Russia follows up these probes with more substantial assaults. Evidence of fortification work or new defensive lines deeper in Zaporizhzhia would indicate that Kyiv is bracing for the reservoir bed to become not just a conduit for small teams, but a staging ground for broader pushes.
