Upper Mississippi River Basin Association Upper Mississippi River Basin Association Water Quality Efforts and Monitoring Strategy Water Quality Efforts and Monitoring Strategy
“We are committed not only to the protection of the River’s water quality, but we are also committed to doing so in a coordinated manner…..We are therefore supporting the coordination of water quality monitoring, assessment, and standards for the Upper Mississippi River by the States of Illinois, Iowa, Minnesota, Missouri, and Wisconsin and the Upper Mississippi River Basin Association. This approach will allow the Clean Water Act to be implemented on the Upper Mississippi River in a more coordinated and consistent fashion than has ever been possible previously.” From the Statement of the Governors of Illinois, Iowa, Minnesota, Missouri, and Wisconsin on Water Quality Protection for the Mississippi River (August 2, 2007).
UMR Clean Water Act (CWA) Program Coordination
States’ Goals• Protect & improve UMR water quality• Improve consistency in CWA program outcomes• Consistent messages to the public • Consistent expectations for the regulated community• Efficient allocation of resources
States’ Approach• UMRBA Water Quality Task Force & Executive Committee• CWA “building blocks”: designated uses, criteria,
monitoring, assessment• Mainstem/local water quality• UMRBA supports the states/increased capacity• Stable, ongoing federal funding needed• Collaborate with other UMR programs and stakeholders
UMRBA Water Quality Work Groups
Water Quality Staffing and Funding
Staffing• Water Quality Program Director• Small portions of other staff time• Temporary staff (none currently)• Contractor support
Funding• States’ voluntary water quality “assessment”
($17,000/yr)• Periodic state and federal grants/contracts

UMR Aquatic Life Designated Uses Project
• Key Question: Are there sufficient differences across the UMR’s floodplain (e.g., main channel v. backwaters) and along its length to warrant distinct treatment when it comes to protecting the aquatic life use?
vegetation)– CWA monitoring strategy– Data management system– Consider programmatic options , including
costs
UMR Nutrients Report Project
Purpose and Approach Survey & synthesis of current
information regarding UMR nutrient monitoring, occurrence, and local impacts
Unique focus – impacts to CWA designated uses on the UMR mainstem Aquatic life Recreation Drinking water
• Findings and Recommendations• Extensive set of options• For states and partners
UMR CWA Monitoring Strategy ProjectRationaleNo unified or comprehensive UMR CWA monitoringExisting programs not designed for CWA purposes nor cover full spatial extentBiology not integratedInconsistent and limited assessments resultALDU, nutrient, and bioassessment project recommendations
Project Purpose“…develop a monitoring strategy framework via a collaborative interagency process to aid the UMR states in moving forward with more comprehensive, consistent, and accurate CWA assessments of the River, leading to both a better understanding of its condition and improvements to its water quality.” - from UMRBA-Illinois EPA funding agreement
UMR CWA Monitoring Strategy Project
ScopeFull longitudinal extentFour lateral strata (where tools available), main channel highest priorityFour major designated uses – aquatic life, drinking water, recreation, fish consumptionChemical, physical, and biological parameters
GoalsCentral goal – support improved assessment of the UMR under the CWAAlso aid other key CWA program functions including standards development, NPDES permits, TMDLs, nonpoint source assessment & management, and measurement of nutrient loading from tributaries

Design Option Description Number of Sites (Approx.) Suggested Implementation Cycle
Fixed Station Current network 65 Annual (monthly/quarterly)
Probabilistic A System-level assessment, Intensification of NRSA 50 Once every 5 years
Probabilistic BMajor longitudinal reach level assessment, Four-fold increase of Probabilistic A
120+ Once every 5 years
Probabilistic C State-level assessment, Follows EMAP-GRE design 150-200+ Once every 5 years; plus
follow-up3 if desired
Probabilistic D1 Thirteen UMR Reach-Level Assessment (30 sites/reach) 390
3-5 year rotation; 1/3 to 1/5 of UMR per year, plus follow-up3 if desired
Probabilistic D2 Thirteen UMR Reach-Level Assessment (15 sites/reach) 195 Once every 5 years; plus
follow-up3 if desired
Nonrandom Longitudinal Survey
Longitudinal sampling “every 5 miles” along “best bank”
total ≈420≈180 baseline over 2 years;≈80/year follow-up over 3
years (≈240);
5 year rotation; 2 year baseline, then3 years of follow-up3
Intensive Pollution Survey
Intensive sampling based on the presence of stressors ≈400 Four year rotation; ¼ of
UMR each year
Main Channel/Side Channel Design Options
UMR CWA Monitoring Strategy ProjectRange of Spatial Intensity in Design Options
Probabilistic Design A Entire river as one system (30-50 sites)
Preliminary Preferences for Recommended Monitoring PlanSupport assessment at the 13 reach level
Scale for monitoring, assessment, management
Must be at least Probabilistic D level of density
Probabilistic D2 plus targeted fixed sites 15 sites per reach, may weight Main channel (perhaps also side channel) Probabilistic best for aquatic life, fish tissue Need supplementary sites for recreation,
drinking water, stressor identification
UMR CWA Monitoring Strategy Project
Preliminary Preferences for Recommended Monitoring PlanMaximize Use of Existing Monitoring
Possible to integrate LTRMP fish data Use existing fixed sites
Incorporate Biology Fish assemblage (EMAP) Vegetation (Pools 3 to 13 only) Macroinvertebrate (kick vs. artificial substrate)
Cost and time 2 years to monitor, repeat on 5 year cycle Estimated $2.5 million to complete
Future refinement foreseen
