[expand]The rivers were obvious water sources. The major waterways crossing steppe—the permanent flows fed by distant mountains or extensive watersheds—provided reliable water, the river locations being geographic constants around which nomadic life organized. The river water quality varied—the clear mountain-fed streams versus muddy lowland rivers, the seasonal variations affecting turbidity, and the upstream activities sometimes affecting safety—but availability was rarely questioned. The river crossings required planning—locating fordable points, timing crossings during low flows, and ensuring entire group plus animals could traverse safely—making river knowledge extend beyond mere location to include crossing techniques.
The lakes presented variable resources. The freshwater lakes provided excellent water—the large water bodies being reliable sources, the stationary location allowing extended stays, and the associated wetlands offering additional resources—making them valuable territories. The saline lakes were useless for drinking—the salt concentration being too high for consumption, the animals refusing water, and the presence indicating water scarcity rather than abundance—requiring recognition preventing deadly mistakes. The lake identification from distance was crucial skill—recognizing size, color, surrounding vegetation, and bird activity indicating whether lake was usable before wasting effort traveling to saline source.
The streams showed seasonal reliability. The small watercourses flowing during spring snowmelt or after major precipitation—the temporary flows providing water when present but drying completely during summer—creating seasonally dependent resources. The stream knowledge included timing—knowing which streams flowed when, the duration of seasonal flows, and the reliability across different years—enabling route planning using temporarily available water. The dried streambeds sometimes indicated underground water—the deeper pools occasionally persisting after surface flow ceased, the vegetation patterns revealing subsurface moisture—making stream reading skill extending beyond merely locating active flows.
