6 Census Data Observations Approximately 70% of the R3 182,000 stream miles have been assessed. Approximately 70% of the R3 182,000 stream miles have been assessed. Of the assessed total (128,000 miles), two-thirds (86,300) are fully supporting aquatic life use. Of the assessed total (128,000 miles), two-thirds (86,300) are fully supporting aquatic life use. R3 has 33,000 Category 5 stream miles (18% of total stream miles) impaired for aquatic life use. R3 has 33,000 Category 5 stream miles (18% of total stream miles) impaired for aquatic life use.

8 Census Data Observations Nearly 12,000 stream miles have had TMDLs completed (Category 4A) and this figure has increased 267% in just 4 years (2004 to 2008). Nearly 12,000 stream miles have had TMDLs completed (Category 4A) and this figure has increased 267% in just 4 years (2004 to 2008). 2,381 waters in the 2002 impaired water inventory have had TMDLs completed for all listed impairments. 2,381 waters in the 2002 impaired water inventory have had TMDLs completed for all listed impairments.

12 Measure Language Options Report of a core set of parameters (e.g. TN, TP, TSS) with improving trends in water quality results in comparison to reference period. Report of a core set of parameters (e.g. TN, TP, TSS) with improving trends in water quality results in comparison to reference period. Reported as percentage gain in defined higher water quality interval. Reported as percentage gain in defined higher water quality interval. Reported as index score gain based on average results in a year. Reported as index score gain based on average results in a year.
