Instream Structure:
• 25 m reaches mapped in June
• Macrophyte bed area volume and relative availability of woody debris measured.

Organic Matter Storage and Transport
• Benthic Organic Matter: 5 sediment cores / section in April and July.
• Particulate Organic Matter: Six two-liter grab samples / section in June 1996 and 
  weekly Oct. ‘98 to Jan. ‘99.

Invertebrates
• Six artificial snag samplers (3 midchannel; 3 at margins) in each section (N=78).  
  Collected every eight weeks from Jan. through Dec. 1996.

• Collections subsampled (1/4 to 1/16) and sorted to order. Ephemeroptera, Plecoptera, and Trichoptera (EPT) identified to genus or species and assigned to functional feeding   groups.

• Incorporated macrophytes and organic debris also collected, categorized by type and surface area determined from dry weight regressions.

Invertebrates reported as number per m² of snag plus organics; thus, density is weighted to dominate habitat type.

Analysis
• ANOVA's run using SAS; Log₁₀ (x+1) transformations when necessary (Box- Cox Plot)
