non-stratification is a common feature in these lakes
with no evidence of persistent thermal stratification
(HAMMER 1981 ; WILLIAMS 1981). The concentration of
suspended solids in Australian inland waters is often described
as being naturally high (DAVIES & WALMSLEY
1985). This is particularly true for shallow, exposed
saline lakes in western Victoria, in which wind generated
turbulence resuspends bottom sediments (WILLIAMS
1981). Secchi depths are very low and may be
