Stations I, 2, and 3 all exhibited a decrease in the total number of taxa observed in 2005. Station I decreased from 25 taxa in 1999 to 22 taxa in 2005, Station 2 decreased from 27 taxa in 1999 to 19 taxa in 2005, and Station 3 decreased from 28 taxa in 1999 to 13 taxa in 2005. Several sensitive species were observed at all the stations in 2005: Mayflies, Epeorus longimanus and Paraleptophlebia sp.; Stonefly, Chloroperlidae; and Caddisfly, Lepidostoma. ~ t . r.. 7 Macrolnvertebrate BCI Comparison Pre and Post Restoration __.

Powell ranch is in good condition with respect to aquatic macro invertebrates. Station I below the Slate Creek bridge exhibited an excellent macroinvertebrate community in 2005 equal to that observed prior to restoration. Station 2 decreased in the number oftaxa, BCI score and CTQa score, . but remains in the excellent category. Station 2 realized in-stream disturbance by others in 2004 and the results indicate purturbation. Station 3 also decreased in the number oftaxa and BCI and CTQa scores, moving it into the good category. Station 3 realized disturbances due to in-stream habitat construction activities by S.G. Company in 2005. The BCI scores already indicate improved conditions with the number of insect taxa (diversity) slower to respond. Migration known as "drift" is a significant re-distribution mechanism for aquatic macroinvertebrates. The rate of return for the number of taxa (to pre-project levels) is related to the size and condition of the watershed above the project. The Blue River is a regulated stream that has a large impoundment above this project. It is reasonable to expect a slower rate of return to pre-project macroinvertebrate diversity. This is the primary reason for reduced number of taxa and lower BCI/CTQa scores in these lower stations. If trends are typical of other restoration project Queen of the River Consultants has completed, these stations will improve dramatically by the next time monitoring is completed. . Channel Stability/Fish Habitat: Channel stability and fish habitat scoring sheets were completed at the same sites as in 1999:(1) Upper above Hwy. 9 at power lines; (2) Middle at Bluffs; (3) Lower at Old Boundary. Channel stability and fish habitat scoring sheets can be viewed in Appendix VI. Comparisons of 1999 and 2005 channel stability and fish habitat ratings illustrated in Table I shows that at all stations conditions have improved due to the restoration activities completed.
