These are not estimates. Each one is a mapped outline, which makes this the most conservative and the most solid of the global counts.<sup><a class=\"fn\" href=\"#sources_1\">1<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">21.2 million lakes are at least 1 hectare<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Extending the same work down one size class by statistical model gives 21.2 million natural lakes of at least 1 hectare. Dropping the threshold by a factor of ten multiplies the count by fifteen, which is the whole problem with the question in one line.<sup><a class=\"fn\" href=\"#sources_2\">2<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">Satellite imagery finds about 117 million<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The GLOWABO database, built from high resolution satellite imagery, contains geographic and morphometric information for roughly 117 million lakes larger than 0.002 square kilometres, which is 0.2 hectares. This is the number most often quoted as the answer, usually without the threshold attached.<sup><a class=\"fn\" href=\"#sources_3\">3<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">A different method gives 64 million<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Working upward from complete geospatial data for the United States, a 2012 study put the global figure at around 64 million water bodies larger than 0.001 square kilometres. That threshold is smaller than the one behind the 117 million figure, and the count is smaller too, which tells you the two studies disagree about method rather than about size.<sup><a class=\"fn\" href=\"#sources_4\">4<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">The highest published estimate was 304 million<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A 2006 model based on the Pareto distribution concluded that the global extent of natural lakes was twice as large as previously known, at 304 million lakes covering 4.2 million square kilometres. It stood as the headline figure for years and has since been revised downwards by both of the satellite based studies.<sup><a class=\"fn\" href=\"#sources_5\">5<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">Every smaller size class holds about ten times more lakes<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Lake sizes follow a near scale invariant pattern: moving one logarithmic step down in surface area multiplies the number of lakes by roughly ten, at least down to 0.1 square kilometres. That single regularity explains why the published totals span two orders of magnitude.<sup><a class=\"fn\" href=\"#sources_6\">6<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">The disagreement is about extrapolation, not measurement<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The 2012 study argues that the Pareto distribution cannot describe the lake size relationship across the whole spectrum, and that extrapolating it downwards has probably overestimated the number of small lakes in the world. That criticism is the reason the highest figure fell from 304 million to 117 and then 64.<sup><a class=\"fn\" href=\"#sources_7\">7<\/a><\/sup><sup><a class=\"fn\" href=\"#sources_5\">5<\/a><\/sup><\/p>\n\n\n\n<h2 class=\"wp-block-heading stat-sec\" id=\"how-much-of-earth\">How much of the planet they cover<\/h2>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">Lakes of 10 hectares and up cover 1.8 percent of land<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The 1.42 million mapped natural lakes have a combined surface area of 2.67 million square kilometres, which is 1.8 percent of the global land area. Large human made reservoirs add another 0.26 million square kilometres, or 0.2 percent.<sup><a class=\"fn\" href=\"#sources_8\">8<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">At 1 hectare the figure rises to 2.2 percent<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Including everything down to 1 hectare gives 3.23 million square kilometres of natural lake surface, 2.2 percent of the land area. Half a million extra square kilometres appear purely from counting smaller water.<sup><a class=\"fn\" href=\"#sources_9\">9<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">The satellite count reaches 3.7 percent<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">GLOWABO puts the combined surface area of its 117 million lakes at about 5 million square kilometres, which it gives as 3.7 percent of the Earth non-glaciated land area. Between this and the 1.8 percent above sits nothing but a definition.<sup><a class=\"fn\" href=\"#sources_10\">10<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">With ponds and farm dams, over 3 percent of land is water<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The 2006 study reached about 4.6 million square kilometres of continental land surface covered by water once lakes, ponds and impoundments are added together, which it summarised as more than 3 percent. Low technology farm impoundments alone accounted for well over 77,000 square kilometres.<sup><a class=\"fn\" href=\"#sources_11\">11<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">Big lakes hold the area, small lakes hold the count<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The satellite work found that large and intermediate lakes dominate total lake surface area, and that small water bodies, while overwhelmingly the most numerous, are not numerous enough to dominate area as earlier extrapolations had suggested. Counting lakes and measuring lake water are two different exercises.<sup><a class=\"fn\" href=\"#sources_12\">12<\/a><\/sup><sup><a class=\"fn\" href=\"#sources_4\">4<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">Lake shoreline is four times the ocean coastline<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The shorelines of all mapped natural lakes run to 7.2 million kilometres, with another 0.5 million for large reservoirs. The global ocean coastline measures 1.6 million kilometres at a comparable map scale. There is roughly four times as much lake edge on this planet as sea edge, and that is before counting anything under 10 hectares.<sup><a class=\"fn\" href=\"#sources_13\">13<\/a><\/sup><\/p>\n\n\n\n<h2 class=\"wp-block-heading stat-sec\" id=\"how-much-water\">How much water they hold<\/h2>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">Natural lakes hold 181,900 cubic kilometres of water<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The mapped natural lakes contain 181.9 thousand cubic kilometres of water, which is 0.8 percent of all non-frozen terrestrial water and equivalent to 1.7 percent of the predominantly fresh groundwater on Earth. Adding large reservoirs brings the total to 187.9 thousand cubic kilometres.<sup><a class=\"fn\" href=\"#sources_14\">14<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">Lakes hold 87 percent of liquid surface fresh water<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Of the fresh water sitting on the surface of the planet in liquid form, lakes hold 87 percent. Rivers, which get far more attention in water policy, hold a small fraction of what lakes do.<sup><a class=\"fn\" href=\"#sources_15\">15<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">The Caspian Sea alone holds 40.2 percent<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Of all the water in the world lakes and reservoirs, 40.2 percent sits in the Caspian Sea. It is usually left out of lake conversations because of its name and its salinity, and leaving it out changes every other percentage on this page.<sup><a class=\"fn\" href=\"#sources_16\">16<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">Five bodies of water hold 73 percent<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The next four largest lakes after the Caspian hold a further 33.2 percent. Five bodies of water therefore account for 73.4 percent of all lake and reservoir water on Earth, and the remaining million and a half lakes share what is left.<sup><a class=\"fn\" href=\"#sources_17\">17<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">Every reservoir on Earth is 3.2 percent of the total<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Total reservoir storage, every large dam impoundment on the planet combined, represents 3.2 percent of the water held in lakes and reservoirs. Human water engineering is visible on maps and marginal in volume.<sup><a class=\"fn\" href=\"#sources_18\">18<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">Spread flat, lake water would be 1.26 metres deep<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Poured evenly over the world landmass, the water in lakes and reservoirs would form a layer about 1.26 metres deep, which is 1.7 times the amount of precipitation falling on land in a year.<sup><a class=\"fn\" href=\"#sources_19\">19<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">The average lake is 3.9 metres deep, and 64.2 metres deep<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Averaging the depth of every lake gives 3.9 metres, because most lakes are small and shallow. Dividing total volume by total area instead gives an area weighted mean depth of 64.2 metres. Both are correct, and the gap between them is the single best illustration of how lake statistics mislead.<sup><a class=\"fn\" href=\"#sources_20\">20<\/a><\/sup><\/p>\n\n\n\n<h2 class=\"wp-block-heading stat-sec\" id=\"how-old-the-water-is\">How old the water is<\/h2>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">The average lake turns over in 1,834 days<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Mean hydraulic residence time across all mapped natural lakes is 1,834 days, about five years. The median is 456 days, well under half of that, because the distribution is dominated by small lakes that flush quickly.<sup><a class=\"fn\" href=\"#sources_21\">21<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">The average molecule of lake water is 255 years old<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Weighting residence times by volume rather than by lake gives an average age for all lake water on Earth of 255 years. The figure is dominated by a handful of enormous lakes, which is exactly what makes it interesting: most lake water on this planet has been sitting still since before most countries existed.<sup><a class=\"fn\" href=\"#sources_22\">22<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">Lake Baikal holds its water for 375 years<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The model puts the residence time of Lake Baikal at 375 years against a reported value of 321. Large lakes in dry catchments sit at this end of the range, while lakes inside a river channel can flush in days.<sup><a class=\"fn\" href=\"#sources_23\">23<\/a><\/sup><sup><a class=\"fn\" href=\"#sources_1\">1<\/a><\/sup><\/p>\n\n\n\n<h2 class=\"wp-block-heading stat-sec\" id=\"where-they-are\">Where the lakes are<\/h2>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">Almost every lake district was made by ice<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Areas of high lake density lie almost entirely within the extent of the last glacial maximum, in northern Canada and Scandinavia and parts of Alaska and Russia. Smaller concentrations appear in the alpine zones of the Andes, Rockies and Himalayas, in the African Rift Valley, and in floodplains such as the Amazon basin and coastal China.<sup><a class=\"fn\" href=\"#sources_24\">24<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">The contiguous United States has 3.5 million lakes<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Complete geospatial data give 3.5 million lakes and reservoirs larger than 0.001 square kilometres in the contiguous United States, excluding the Great Lakes, with a combined surface area of 131,000 square kilometres.<sup><a class=\"fn\" href=\"#sources_25\">25<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">Alaska adds between 1 and 2.5 million more<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The same study found incomplete data for Alaska suggesting the state holds 1 to 2.5 million lakes larger than 0.001 square kilometres, covering over 50,000 square kilometres. Alaska on its own has more lake surface than a third of the lower 48 combined.<sup><a class=\"fn\" href=\"#sources_26\">26<\/a><\/sup><sup><a class=\"fn\" href=\"#sources_2\">2<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">The United States holds roughly a twelfth of the world lakes<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Setting 4.5 to 6 million American lakes against the 64 million global figure from the same study puts the United States at 7 to 9 percent of the world total. This is our own arithmetic on that study two figures, not a published statistic, and it only holds at the 0.001 square kilometre threshold both were measured at.<sup><a class=\"fn\" href=\"#sources_27\">27<\/a><\/sup><sup><a class=\"fn\" href=\"#sources_2\">2<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">No country by country census exists<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">There is no global dataset that counts lakes nation by nation at a consistent threshold, which is why claims such as one country holding more lakes than the rest of the world combined cannot be checked and should not be repeated. What can be said is that against a global figure of 64 or 117 million, no single country comes close to half.<sup><a class=\"fn\" href=\"#sources_28\">28<\/a><\/sup><sup><a class=\"fn\" href=\"#sources_3\">3<\/a><\/sup><\/p>\n\n\n\n<h2 class=\"wp-block-heading stat-sec\" id=\"what-is-changing\">What is changing<\/h2>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">53 percent of the largest lakes are losing water<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Three decades of satellite observation of the 1,972 largest lakes on Earth found statistically significant declines in stored water in 53 percent of them between 1992 and 2020. This is the clearest measured trend in global limnology, and it runs one way.<sup><a class=\"fn\" href=\"#sources_29\">29<\/a><\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading stat-h\">A quarter of humanity lives beside a drying lake<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The same study estimates that roughly one quarter of the world population lives in the basin of a lake that is losing water.
