In the range of altitude from 1100 to 1850 m above sea level the mean rainfall totals over a 10‐year period from June to September as measured by means of 22 storage gages with horizontal orifices and wind shields generally decreased with increasing elevation in the upper part (6.8 km 2 ) of the prealpine watershed of Baye de Montreux. The substitution of a stereo orifice for the horizontal one on the nine gages located on the slopes open to rain‐bearing winds resulted in a slightly increasing mean rainfall catch with increasing elevation ( r =0.430). After 23 ground level stereo gages were set up in the watershed, a visible improvement in the rainfall‐elevation relationship was registered ( r =0.710).
