✦ Synopsis

Measurements made on the floors of the temporarilydrained Glenfarg and Glenquey Reservoirs indicate that sediments with wet volumes of 63.94 x lo3 m3 and 1264 x lo3 m 3 were deposited in 56 and 73 years respectively. These figures represent 2.5 per cent and 1.1 per cent losses of original storage capacity. When corrected for water, organic, and diatom skeleton contents,and reservoir trap efficiency inorganic sediment yields of at least 31.3 tonnes km-2yr-1 and of 9.0 tonnes km-2yr-1 are suggested. The difference is probably related to contrasts of land use.
