<br />) <br /> <br />interest: in Millard Canyon (RM 33.5), a juvenile razorback <br />sucker was collected. This 203mm fish was part of a stock <br />of razorback that was hatched in 1993, and stocked near <br />Split Mountain on October 31, 1996. It appeared to be in <br />excellent condition after we collected it nearly 300 miles <br />downstream. <br /> <br />Table 1- Summary of ISMP adult electrofishing, 1997. <br /> River Flow # of CS Mean <br />Reach Miles Date (CFS) AD.

The <br />goal of sampling 48 backwaters (two per five mile reach) was <br />met, however some of these were sub-ISMP standard, and in a <br />few a second seine haul was not taken. Fish from all primary <br />seine hauls (the first haul in a five mile reach) were either <br />counted and identified in the field or preserved for later <br />analysis. Those fish were transferred to the Larval Fish <br />Lab. Although every effort was made to identify CS in the <br />field, smaller CS may have been preserved. <br /> <br />This year the peak spring flow was above average at over <br />33000 cfs. Flows in the Green River remained unusually high <br />all year, resulting in poor reproductive success for the <br /> <br />3 <br />
