If mountain glaciers disappear there will be no source for many mountain streams, which will then dry up. Many rivers will be reduced in size as a result.
As the glaciers receded with gravity pulling them downstream they created our valleys. Where I live in the Northeast part of the US we are in Wyoming Valley in Pennsylvania.
Water
Glaciers or moving, shifting and melting constantly. The worst that could happen is if too meltwater was created by the melting glacier it would cause a flood downstream.
An ice front recedes when a glaciers rate of melting is greater than its rate of movement. It is the end of the glacier.
glaciers move them downhill and scratch the surface of the valley from a river 'v' to a glacial 'u' they also move lots of rocks. rivers move rocks downstream the higher upstream the more rough and sharp edged they are, downstream they are smoother and rounder due to erosion.

Water
At the end of the last glaciation most glaciers melted as the climate changed, except for those in the far north and in mountainous areas.
The lower parts of glaciers melt and the water flows to fill the rivers downstream. If global warming causes the whole glacier to melt, then the rivers will lose their mountain supply and the lives of people downstream, who rely on water for living and agriculture will be threatened.
Close to the glacier, it will be quite a milky grey colour due to the rock flour. And your system does not tolerate well this contaminant. A little further downstream, it will be drinkable.

Downstream
False
solid (when it originates from the glaciers) and then liquid (all the way to the end)
