Critical Low Outflow Ihefu Swamp
MENU Overflow Ihefu Swamp reaches critical low level on September 22, 2026 With the critical low outflow at VDAS 405 (idodi) some 30km downstream of the N’giriama sill, zero flow at Park HQ is immenent and expected in October 2026.
Flow status Usangu Rice Drainage
MENU September 12, 2026 Alert 3 Confirmed Nyaluhanga reached an advanced low-flow transition in mid-September 2026.On 7 September, both fixed branch-inlet indicators (A16 and A17) were still WATER-classified. A16 changed to NO-WATER by 12 September while A17 remained WATER, marking the presently identified candidate ALERT 3 transition on 12 September. A17 subsequently changed to NO-WATERContinue reading “Flow status Usangu Rice Drainage”
