• The Environmental Condition Grade is comprised of multiple indicators that are assessed against established guidelines, resulting in a single grade for each catchment or bay zone.
• A = Excellent: Conditions meet all guidelines. All key processes are functional and critical habitats are in near pristine condition.
• B = Good: Conditions meet guidelines for most of the reporting area. Most key processes are slightly impacted and most critical habitats are intact.
• C = Fair: Conditions are close to meeting guidelines in most of the reporting area. Key processes are impacted but still functional and critical habitats are impacted.
• D = Poor: Conditions meet few of the guidelines in most of the reporting area. Many key processes are not functional and most critical habitats are impacted.
• F = Fail: Conditions do not meet the set guidelines. Most key processes are not functional and most critical habitats are severely impacted.
• NB: The 2015 Environmental Condition Grades are not directly comparable to previous years due to the evolved methodology which includes measures for additional pressures and key habitats.

• A number of indicators are assessed and combined to calculate one overall Environmental Condition Grade per catchment.
• 0.0 = Fail to 1.0 = Excellent
• N/A: Indicator not applicable for this catchment

• 
  Maximum benefits: The local community receives full social and economic benefits from waterways.
• 
  Very high benefits: The local community receives the majority of social and economic benefits from waterways.
• 
  High benefits: The local community receives many social and economic benefits from waterways.
• 
  Moderate benefits: The local community receives only a few social and economic benefits from waterways.
• 
  Minimum benefits: The local community receives almost no social or economic benefits from waterways.
• NB: A Waterway Benefits Rating for the bay zones and Broadwater will be explored in future years.

• A number of indicators are assessed and combined to calculate one overall Waterway Benefits Rating per catchment.
• 0.0 = Minimum to 1.0 = Maximum
• N/A: Indicator not applicable for this catchment

• The following indicators are measured on a scale of 0 to 1 (based on a percentage or relative to the South East Queensland average)
