Potential impact on the environment

Water availability in the river and trends

Yes (Observed sharp reduction in seasonal water availability instream for two years for dry and wet seasons).

Very high flows in the rainy season and water not available for flow in the river the dry season only existing in small pools.

Rainfall run off patterns and nature

Yes (observed higher rainfall-runoff peak for second monitoring season). Reported rainfall increase and higher flow peaks but longer low flow and no flow seasons

High hydrologic response slope curve can mean sharp rainfall-runoff hydrograph curve and dry season low water availability instream.

Rainfall trends

· Change in timing of rainy season towards start and earlier in the year (October to Deceember) from end-year away from December toJanuary

· Increase in length of dry seasons

· Increase in amounts for rainfall events

· Increase intensity of dry season rain days

Seasonal changes can affect water availability instream

River flow trends

· Higher river flow peaks

· Shorter time of flow seasonal flows

· Less sedimentation

High flows in the rainy season observed only for the field data collection time
