Paddle design Summary

Paddle with letter ‘P’ in middle indicates provisional classification of ‘good’

Good: Based upon incomplete information available to date, bacterial water quality appears to be safe for swimming most of the time.

Orange paddle with letter ‘P’ in middle indicates provisional classification of ‘fair’

Fair: Based upon incomplete information available to date, bacterial water quality appears to be fair (variable) at this location.

Red paddle with letter ‘P’ in middle indicates provisional classification of ‘poor’.

 Poor: Based upon incomplete information available to date, bacterial water quality often appears to be unsatisfactory for swimming.

Two tone paddle, with left half green and right half orange, indicates bacterial water quality results to date are good, but primarily animal pollutant sources may elevate bacterial levels following rainfall

 MAC: Based upon incomplete information available to date, bacterial water quality appears to be safe for swimming most of the time.

 paddle, with left half green and right half red, indicates bacterial water quality results to date are good, but animal and stormwater contamination sources are likely to elevate bacterial levels to high levels following rainfall.

MAC: Based upon incomplete information available to date, bacterial water quality appears to be safe for swimming most of the time.

Two tone paddle, with left half orange and right half green, indicates bacterial water quality to date is variable, but few contamination sources have been identified

 MAC: Based upon incomplete information available to date, bacterial water quality appears to be fair (variable) at this location.

Two tone paddle, with left half orange and right half red, indicates bacterial water quality to date is variable, but but animal and stormwater contamination sources are likely to elevate bacterial levels to high levels following rainfall

MAC: Based upon incomplete information available to date, bacterial water quality appears to be (fair) variable at this location.

Two tone paddle, with left half red and right half green, indicates bacterial water quality to date is poor, but few contamination sources have been identified

 MAC: Based upon incomplete information available to date, bacterial water quality appears to be unsatisfactory for swimming.

Two tone paddle, with left half red and right half orange, indicates bacterial water quality to date is poor, but contamination sources at the site have not been confirmed 

 MAC: Based upon incomplete information available to date, bacterial water quality appears to be unsatisfactory for swimming.

Green paddle indicates final classification of ‘good’ or very good bacterial water quality

 Very Good or Good: Bacterial water quality is considered safe for swimming most if not at all times.

Orange paddle indicates final classification of ‘fair’ bacterial water quality

 Fair: Bacterial water quality is variable at this location. However, water quality is generally safe for swimming.

Red paddle indicates final classification of ‘poor’ or ‘very poor’ bacterial water quality

Poor or Very Poor: Bacterial water quality is often unsatisfactory for swimming. Avoid swimming at this location.

Blue paddle indicates new sample site.

 New Sample Site: Insufficient water quality or site information is available to assign a bacterial risk classification.

Purple paddle indicates proposed new sample site

 Proposed New Sample Site: This site is currently been considered for future bacterial water quality monitoring.
