Shallow Groundwater Trends for the West Wimmera
B.J. Muller and M. Hocking (September 2002). DPI Centre for Land Protection Research. Monitoring Report No. 46.

Eight key bores within the West Wimmera Region were selected for the analysis of shallow groundwater trends, six managed by SKM, one by South Australia and was managed by CLPR. Regional groundwater monitoring information revealed that the majority of bores displayed water levels that respond to climatic variation. However, groundwater trends in the central part of the catchment did not display this reaction and have remained consistently flat throughout the monitoring record. Similarly, the Edenhope township groundwater trends do not reflect climatic change with water levels rising at a rate of 26 cm/yr. This steep trend may be a result of urban inputs to the watertable. Thus attention to land and water management issues is a high priority in order to prevent saline contamination of the town’s water supply (Lake Wallace).
