What’s ahead: 2004• Refinement of wadeable indicators
and reference conditions– Assess water quality– Support management decisions– Assess criteria compliance– Evaluate program effectiveness– Develop, adopt or revise water
quality standards• Develop criteria and indicators
– Periphyton bioassessments• Nonwadeable bioassessment
methods and indicators

SWPBA – 2019
Be there or be Square!!
SWPBA Survey: 1996 vs. 2004 vs. 2012
Four Basic Questions: • Number and type of bioassessments
conducted• Where we are conducting
bioassessments• Why we are conducting bioassessments• Number and experience of biologists
adem.alabama.gov
SWPBA Survey: 1996 vs. 2004 vs. 2012
Bioassessment Tools• Macroinvertebrate Assessments

• Fish IBI• Periphyton
– Diatom Community Assessments– Rapid Periphyton Survey– Periphyton Chl a
• Phytoplankton• Zooplankton• Water column Chl a• Amphibian Surveys• Plant Community Surveys

SWPBA Survey: 1996 vs. 2004 vs. 2012
Waterbodies Assessed• Wadeable streams and rivers• Nonwadeable streams and rivers• Lakes, reservoirs, and ponds• Wetlands• Other
– Springs– Estuaries– Headwaters

Accomplishments: 2004-2012
• 4 additional states conducting periphyton assessments and identifying diatoms
• 3 additional states working in nonwadeable streams and rivers
• 4 states working in wetlands
• Refinement of indices for wadeable streams and rivers
• Database development
• Increase in collection of data that meets multiple objectives
adem.alabama.gov
What’s Ahead: 2012
• Indicator and method development– Nonwadeable streams and rivers– Wetlands– Lakes and reservoirs?
• Estimate overall water quality• Assess trends in water quality
adem.alabama.gov
What’s Ahead: 2012The “maybe so, maybe so”
initiatives• Indicator and method development
– Nonwadeable streams and rivers– Wetlands– Lakes and reservoirs?
• Estimate overall water quality• Assess trends in water quality• Refinement of indices and reference
conditions– Highly disturbed areas– Shared ecoregions
• Development WQ Criteria and Standards– Biological condition gradients– Tiered aquatic life uses– Protection of healthy watersheds?
