Water Level Fluctuations (WLFs) indices
Two differently time-lagged indices were used as indicators of water
level fluctuations in Lake Baringo as proposed by White et al.(2008): (1) the difference from the long-term mean (DLTM) (m) was
calculated by determining the mean water level from 1956 to 2020 for the
lake and then subtracting that mean value (across years) from the mean
water level for a particular year. These calculations result in positive
and negative values indicating the mean water level for a particular
year relative to the lake’s overall long-term mean. (2) the annual
amplitude (WLamp, m) determined as the difference between the lowest and
highest recorded lake level within a year (WLmax-WLmin) provides a
measure of the strength of the flood pulse for that particular year.
