Here’s something that doesn’t make sense until you hear the backstory: one of the most consistently productive fishing spots near Tbilisi started out as a salt pan with no fish in it. Not “poor fishing.” Not “needs restocking.” Actually, literally, chemically incapable of supporting fish. The water was so saline that nothing lived in it except some very specialized microorganisms.
Today, Kumisi Lake covers over 5 square kilometres and produces reliable catches of common carp, grass carp, silver carp, and catfish. It’s the closest thing Georgia has to a properly managed recreational pay-lake, and anglers who know about it keep going back. The story of how it got from A to B is one of the stranger chapters in Georgian environmental engineering.
What Kumisi Used to Be
Before 1967, Kumisi was tiny – less than half a square kilometre – and shallow enough to wade across. Maximum depth: 50 centimetres. The water was hyper-saline, with mineralization levels around 2,700 milligrams per litre. For comparison, freshwater typically runs below 500 mg/l. The sea at Batumi is around 18,000 mg/l. So Kumisi wasn’t quite seawater, but it was closer to the Black Sea than to a river.
People did visit, but not for fish. The lake’s sulfide-rich mud had a local reputation for treating skin conditions and joint pain, a sort of natural spa for the rural communities south of Tbilisi. But as a fishery, it was worthless. A salty puddle in a dry plain.
The Transformation
In 1967, Soviet planners looked at Kumisi and saw not a salt pan but a recreational opportunity. The plan was audacious: drain the saline water, then pump in massive volumes of freshwater from the Mtkvari and Algeti rivers through newly constructed canals.
The engineering worked. The salinity crashed. The surface area exploded from 0.48 square kilometres to 5.4. The maximum depth went from 50 centimetres to 4 metres. Within months, a fishless salt flat had become a warm, eutrophic freshwater lake.
Warm water plus high nutrients equals high biological productivity. The newly freshwater Kumisi bloomed with aquatic vegetation, insects, and zooplankton. And where there’s food, you can add fish.
The Pay-Lake Model
Kumisi today operates as a commercial recreational fishery. You pay to fish, you catch stocked fish, and the operators keep restocking to maintain the action. It’s about as far from wild fishing as you can get, but it serves a specific niche: anglers who want to catch something reliably, without the four-hour drives, the hiking, and the blank sessions that characterize much of Georgian fishing.
The stocked species are the standard aquaculture lineup: common carp, grass carp (White Amur), silver carp, bighead carp, and crucian carp. Catfish are present in smaller numbers. The operators supplement natural food with commercial feed, which keeps growth rates high and fish condition good.
Is it wild? No. Is it natural? The entire lake is an artificial construct – the word “natural” stopped applying in 1967. But on a hot Sunday when you’ve got a few hours to fish and don’t want to drive to Zhinvali, a managed lake with guaranteed fish starts to look pretty good.
The Irony
There’s a deep irony in Kumisi’s success. Across Georgia, wild fisheries are in decline. Paravani’s vendace are collapsing. The Algeti’s native cyprinids are being eaten by illegally introduced zander. Saghamo’s biodiversity has been flattened by Prussian carp. The Mtkvari mainstem is showing alarming parasite loads linked to pollution.
And yet Kumisi – the one lake in Georgia that has zero claim to ecological authenticity – is thriving. The fish are healthy. The catch rates are consistent. The business model works.
It’s tempting to draw a pessimistic conclusion from this: that the future of Georgian fishing lies in managed, artificial fisheries rather than wild waters. I don’t think that’s quite right. But I do think it tells us something about what happens when you actively manage a fishery – monitoring stocks, controlling harvest, restocking strategically – versus leaving it to market forces and hoping for the best.
The Soviet engineers who transformed Kumisi weren’t thinking about ecology. They were thinking about recreation access for Tbilisi residents. But in the process, they accidentally created a model for what Georgian fisheries management could look like, if anyone decided to invest in it.
Fishing Kumisi Today
If you want to try it, Kumisi is about 40 minutes south of Tbilisi, accessible via the main road toward Marneuli. It’s well signposted. You’ll see the entrance, you’ll pay at the gate, and you’ll fish.
Bring standard carp gear: a medium-heavy feeder rod, boilies or corn, and a landing net. The fishing isn’t complicated. That’s the point. Pick a swim, bait up, cast out, and you’ll probably catch something. In a country where fishing often means hard work, long drives, and uncertain results, there’s something to be said for a place where the fish actually cooperate.

Image 1 (hero): A bright, sunny shot of Kumisi Lake showing anglers fishing from the shore with the lake stretching out behind them. The image should communicate a relaxed, accessible fishing experience – not wilderness, but pleasant.
Image 2 (inline, after “What Kumisi Used to Be”): If possible, a historical photo of the area before the transformation (1960s if available). If not, a modern photo of a saline depression or salt flat in Georgia that looks similar to what Kumisi would have been – cracked white salt crust, dry landscape.
