Jimperding Catchment

The Jimperding Catchment lies in the south of the Shire of Toodyay. It has a catchment area of 150 square kilometres (15,000 ha), and is predominately an agricultural area. It currently doesn't have an active catchment group.

The Jimperding Brook has, however, been the subject of continual monitoring for a number of years. The possibility of a Class 4 waste disposal site being located at the top of Jimperding Brook prompted the former Jimperding Catchment Group to include in their monitoring program (funded by the National Landcare Program) a baseline study of the catchment. This complimented their original project of salinity monitoring in the catchment.

From July 1997 to June 2000, Edith Cowan University (ECU) undertook the baseline project. The report prepared for the Toodyay LCDC, "Results of the Jimperding Brook Monitoring Project, Bloom. Lyn, Clarke. Wayne, and Judd. Simon, 26 September 2002", provides the baseline study, and can be found here.

Jimperding Brook Foreshore and Channel Assessment

The Western Australian Department of Water and the Avon Waterways Committee, as part of their 'Water resource management series, have prepared a Foreshore and channel assessment of Jimperding Brook (Report WRM 48, Feb 2008). This was an Avon Catchment Council project delivered by the Department of Water and funded with investments from the Australian and Western Australian Governments through the Natural Heritage Trust and the National Action Plan for Salinity and Water Quality.
