The most severe constraints for agriculture are water shortages in semi-arid areas of Northern Ethiopia. Rainfall is extremely variable; therefore, it is necessary to harvest rainwater to safeguard improved crop production. The objective of the study is to characterize, identifying problems and evaluating the performance of existing RWH systems in the Wag-Lasta areas. Tweleve RWH ponds were selected from six kebeles in the study area. Primary and secondary data were collected and evaluated using descriptive statistics to assess the technical performance of water harvesting ponds by field observation, direct measurements, and interviews with zone, woreda, kebele experts, and owners. The technical performance assessment showed that the collected runoff and system efficiency were negligible for the total rainwater catchment area. The problems in a portion of the non-functional ponds had found to be poor site selection, lack of maintenance, and standardization of techniques, and some of them were efficient with low performance.
