when Nicolett mapped it in 1839 it was fairly shallow and had no discernable outlet ... but that has changed and the lake has overflowed numerous times and flooded the entire area ... the question I have is this: what is the source of all this salt? |

Saline is always present in a lake that has no outlet. Lets take Mono Lake as an example. Mono Lake is a remnant of a much larger body of water that covered much of the surrounding region after melting of glaciers 750,000 years ago. Like many similar lakes of the Great Basin Desert in Nevada, there is no outlet so the water can only leave naturally by evaporation, and hence the water has a high salt content - three times that of the sea. The lake level fell steadily after 1941 due to water removal from its tributary streams to supply cities in Southern California, principally Los Angeles, although this practice ceased following a protection order issued in 1994. The surface elevation is now gradually rising. |

the difference here is that this is not a SINK this lake is a SOURCE and that is a huge difference and the topography with this lake is much different the lake is on a plateau and has little drainage to it |

Here's a closer lake in characteristics to Spirit Lake. Crater Lake, Oregon. Been there a few times myself. And in make believe land, on the Flight Simulator, landed the float plane on it, and spent the night on Wizard Island. The lake partly fills a 2,148-foot-deep (655 m) caldera[3] that was formed around 7,700 (± 150) years ago[4] by the collapse of the volcano Mount Mazama. No rivers flow into or out of the lake; the evaporation is compensated for by rain and snowfall at a rate such that the total amount of water is replaced every 250 years.[citation needed] With a depth of 1,949 feet (594 m),[5] the lake is the deepest in the United States. In the world, it ranks ninth for maximum depth, and third for mean (average) depth.[6] Due to several unique factors, mainly that the lake has no inlets or tributaries, the waters of Crater Lake are some of the purest in the world because of the absence of pollutants. Clarity readings from a Secchi disk have consistently been measured as being 120 ft (37 m), which is very clear for any natural body of water.[37] In 1997, scientists recorded a record clarity of 142 ft (43 m). The lake has relatively high levels of dissolved salts, total alkalinity, and conductivity. The average pH has generally ranged between 7 and 8.[38] Eventually, the caldera cooled, allowing rain and snow to accumulate and form a lake. Landslides from the caldera rim thereafter formed debris fans and turbidite sediments on the lake bed. Fumaroles and hot springs remained common and active during this period. Also after some time, the slopes of the lake's caldera rim more or less stabilized, streams restored a radial drainage pattern on the mountain, and dense forests began to revegetate the barren landscape. It is estimated that about 720 years was required to fill the lake to its present depth of 1,949 feet (594 m). Much of this occurred during a period when the prevailing climate was less moist than at present.[25] Some hydrothermal activity remains along the lake floor, suggesting that at some time in the future, Mazama may erupt once again.[26] |

maybe you missed that part about the water being salty and it being a SOURCE of that salty water ... keep looking though ... but please try to find some body of water that matches the criteria established by Spirit Lake |

Of course it is the source of salt water. In your linked article, it mentions clearly that Devils Lake is an Endorheic Basin Lake. Sounds like Crater Lake to me. But in my opinion, the salt content is due to mega years of not overflowing, creating the highly saline waters. This is a great year to view a good winter and rainfall, for Devils Lake to overflow. Heck, all lakes are overflowing this year. Lets hope this trend continues. Now I read about the challenges down stream, from unseasonable weather, which is normal in every sense. And when people get in the way of nature, Nature will always win, but with vengeance. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Devils Lake is the endorheic, or closed, lake of a drainage basin of some 3,800 sq mi (9,800 km2), the Devils Lake Basin. The lake collects around 86 percent of the basin's water runoff.[9] Above an elevation of 1,447 ft (441 m) AMSL, the lake spills into neighboring Stump Lake. At 1,458 ft (444 m), the combined lake flows naturally into the Sheyenne River, though the lake has not reached this level in approximately 1,000 years.[10] The Sheyenne River is a tributary to the Red River, which flows into Canada, with eventual exit into the Hudson Bay.[9] Dike protection is set at 1,454 ft (443 m). Under normal conditions, Devils Lake is shallow, saline, and hypereutrophic (very high in nutrients). During periods of excessive precipitation, however, the lake can be up to 60 ft (18 m) deep, eutrophic (rich in minerals, nutrients, and organisms), with decreased salinity due to dilution.[9] Salinity[edit] Because Devils Lake is endorheic, the lake tends to be much higher in salinity than are lakes with outlets to river systems. This is similar to the Great Salt Lake in Utah.[11] Lower water levels increase salinity threatening fish and wildlife.[11] Salinity levels in the lake have been one prominent aspect of the debate over diversion of lake water into the Sheyenne River, with questions of the potential environmental impact of the diverted water on downstream rivers, lakes, and communities.[12] |

the water in the lake was salty in 1839 when lake levels were low ... it has been salty since the Dakota began living near it ... where does the salt come from is my question and you are no nearer to an answer than when I posted the link |

Ok Georg, Every post I sent thus far, and every link I provided, explains why and how the salt came from and was created. To put it as simple as I can, "The lake creates the salt, due to it's characteristics". Just because devils lake overflows, does not mean it will not remain salty. Please review the link again, that I linked in my last post, about Endorheic Lakes. It clearly names Devil Lake and all the others that create salt. |

and again, what is the source of all that salty water? it is an isolated basin and the topography does not permit much drainage from a highland which is not there ... put on your thinking cap |

the people who write these blurbs for Wikipedia also fail ... they don't even raise the question of their being a SOURCE of salt from under the earth ... we all know about Yellowstone and its mud volcanoes and so forth and its hot springs having a magma thermal sources, but that issue is not even considered by the "expert authors" where even the word "author" injects authority as an assumption ... I had a funny feeling when I first read what Joseph Nicolett wrote about the place ... he mapped it and then soon left the area and he died within four years of his visit |
