Lachlan River (Condobolin) Floodplain Risk Management Study and Plan

Study Objectives

Lachlan Shire Council commissioned the Floodplain Risk Management Study and Draft Plan for the town of Condobolin. The overall objectives of the Floodplain Risk Management Study (FRMS) were to assess the impacts of flooding, review existing Council policies as they relate to development of land in flood liable areas, consider options for the management of flood affected land and to develop a draft Floodplain Risk Management Plan (FRMP) which:

  1. Proposes modifications to existing Council policies to ensure that the development of flood affected land is undertaken so as to be compatible with the flood hazard and risk.
  2. Proposes Flood Planning Levels for the various land uses in the floodplain.
  3. Sets out the recommended program of works and measures aimed at reducing over time, the social, environmental and economic impacts of flooding.
  4. Provides a program for implementation of the proposed works and measures.

The FRMS focusses on Main Stream Flooding from the Lachlan River and is major tributaries (namely Goobang Creek) and Major Overland Flow (areas which occur in the urbanised parts of the town, as well as the presently undeveloped areas immediately to its north. Flooding problems on the Major Overland Flow paths arise from surcharges of the trunk drainage systems, which comprise a mix of natural depressions, pipes, culverts and open drains.

The solutions of problems resulting from surcharges of minor drainage lines in streets or in individual allotments remote from the Major Overland Flow paths are matters for stormwater management by Council and are outside the scope of the present investigation.
