River Murray and Lower Lakes catchment risk assessment for water quality: Results and management options Risks to recreational use Figure 2.6 is the key map for risks to the recreational environmental value in the RB LAP area. The attached DVD has individual maps numbered according to the key map. Note: only hazards identified in the shaded areas were assessed for risk to recreation Figure 2.6 Key map for recreation zones, RB LAP area Frequencies of identified risks to recreation for the various water quality parameters are summarised in Table 2.5. The highest frequency of risks to recreational values was for pathogens, followed by nutrients, turbidity and hydrocarbons. The majority of these risks (124) were assessed as low level, although a significant number (69) of moderate-level risks were identified, mostly pathogen risks. 37
