Criterion B, (Green River): Proximity to a known or planned razorback sucker <br />spawning area <br />5 = within 1-25 river miles downstream of a spawning area <br />4 = within 26-50 river miles downstream of a spawning area <br />3 = within 51-75 river miles downstream of a spawning area <br />2 = more than 75 river miles downstream of a spawning area <br />1 = upstream of a spawning area <br />Criterion B2 (Colorado River): Proximity to recent adult razorback sucker <br />captures (using data from 1974-1993, [Burdick <br />1992; Quarterone 1993]) <br />5 = 100 captures <br />4 = 50-99 captures <br />3 = 15-49 captures <br />2 = 6-14 captures <br />1 = 0-5 captures <br />Criterion C: Having a June hydrological connection to the river <br />3 = yes <br />2 = unsure <br />1 = no <br />Criterion D: Potential for network (complex) of bottomland sites <br />5 = yes, z 8 sites <br />4 = yes, 6-7 sites <br />3 = yes, 4-5 sites <br />2 = yes, 2-3 sites <br />1 = no, only 1 site <br />Step 5: The sub-criteria raw scores were then multiplied by the total <br />average weighted point values to produce a total score for each bottomland <br />site. The total score was sorted from the lowest to the highest with the <br />highest total score receiving the lowest ordinal rank and lowest total score <br />the highest ordinal rank. The lowest ordinal rank was the top priority site <br />and the highest ordinal rank was the lowest priority site in the bottomland <br />inventory. The Green River drainage was scored and prioritized independently <br />from the Colorado and Gunnison river drainages. <br />Geomorphology <br />Three general geomorphological categories were used to simplify <br />bottomland classification and identify habitat types. These categories were <br />floodplain depression, floodplain terrace, or gravel-pit pond (Figure 2). <br />These three categories were the most numerous encountered in the inventory, <br />although there were other habitat types such as canyon mouths. <br />10
