<br />. <br /> <br />. <br /> <br />e <br /> <br />Fisheries population and standing crop estimates based on adult trout in samples is illustrated in <br />Figure 1. Standing crop estimates comparing 1999,2002,2003, and 2005 data, were completed for <br />each electrofishing station and can be viewed in Figure 6. Standing crop estimates in 2005 for <br />Station 1 were estimated at 871.0 lbs. fish/acre, an increase of 224 lbs./acre from 2003 sampling. <br />Standing crop of trout at Station 1 has increased 33 fold over pre -restoration levels. Station 2 was <br />not sampled in 2005 but results in 2003 indicate a 45 Ibs/acre increase over 2002 estimates. Station <br />2 did not have a pre-restoration sample taken. Station 3 was estimated at 283.0 lbs. fish/acre, an <br />increase of 181lbs./acre from 2003 sampling. Station 3 standing crop of trout has increased 4 fold <br />over pre-restoration levels. Station 4 was not sampled in 2005 but realized a 4.4 fold increase in <br />trout standing crop from 1999 through 2003. Other station trends indicate that additional <br />improvements occured in 2005 at Station 4. Station 5 was 145.0 lbs. fish/acre in 2005, an increase <br />of75.2lbs./acre from 2003 sampling. Station 5 realized a 12 fold increase in trout standing crop <br />between 1999 and 2005. <br /> <br />The macroinvertebrate community was monitored using the Biotic Condition Index (BCI). BCI <br />provides a comparison of the existing macro invertebrate community with a theoretical optimum <br />community derived from many decades of sampling similar streams in the Rocky Mountain West. <br />Use of a before and after <br />approach provides insight Fig. 6 <br />into the potential effect(s) of <br />this project on the river. <br />Comparison of 1999 and <br />2005 macro invertebrate data <br />can be viewed in Figure 7. <br />Station 1 had CTQa values <br />of 52 in 1999 and 54 in 2005 <br />and BCI values of 91 in 1999 <br />and 93 in 2005. Station 2 had <br />CTQa values of 49 in 1999 <br />and 56 in 2005 and BCI <br />values of 102 in 1999 and 89 <br />in 2005. Station 3 had a <br />CTQa values of 50 in 1999 <br />and 62 in 2005 and BCI <br />values of 100 in 1999 and 81 <br />in 2005. Data from Station 1, in both 1999 and 2003, placed the station in the excellent range for <br />both CTQa and BCI. Data from Station 2 placed it in the excellent category for CTQa and excellent <br />for BCI in 1999 and excellent for CTQa and good for BCI in 2005. Data from Station 3 placed it <br />in the excellent category for both CTQa and BCI in 1999 and good for both CTQa and BCl in 2005. <br /> <br />· Macroinvertebrates: <br /> <br />Comparative Trout Standing Crop <br />Blue River, Mt.
