<br />Page 50 <br /> <br />HUC 1405 - One population of each species. Flannelmouth and bluehead sucker are considered <br />abundant in the White River, though roundtail chub is considered rare. Maintenance of these <br />populations will be considered success in this drainage. <br /> <br />HUC 1406 - Twelve populations each of bluehead and tlannelmouth sucker, seven populations of <br />roundtail chub. Bluehead sucker are known to currently be present in the Green, Duchesne, <br />Strawberry, and Price rivers and in Ashley, Cottonwood, Huntington, Ferron, and Red creeks. They <br />are either not present or status is unknown in the following: Uinta, Lake Fork, and San Rafael rivers <br />and A vintaquin and Currant creeks. Flannelmouth sucker distribution is similar except that they are <br />moderately abundant in A vintaquin Creek, rare in the San Rafael, and not present in Huntington <br />Creek. Distribution of the roundtail chub within this unit is more restricted. . They are rare or <br />moderately abundant in the Green, San Rafael, and Duchesne rivers and not present (or status <br />unknown) in the remaining streams recently surveyed. <br /> <br />HUC 1407 - Nine populations of blue head sucker, six populations oftlannelmouth sucker, and three <br />populations of roundtail chub. Bluehead sucker are present in Ivie, Quitchupah, Pine, and Mamie <br />creeks and the Fremont, Escalante, and Colorado (above Lake Powell) rivers. They were not found <br />during Muddy Creek surveys during 2005 and their status is unknown in the Dirty Devil River. <br />Flannelmouth sucker are present in the Colorado River above Lake Powell, the Escalante and <br />Fremont rivers, and in Ivie and Sand creeks. They are considered not present or status unknown in <br />the Dirty Devil River and Muddy and Quitchupah creeks. Roundtail chub are present, but rare in the <br />Colorado River mainstem above Lake Powell and the Escalante River. They have not been observed <br />in recent surveys in the Dirty Devil River or the Muddy Creek drainage. <br /> <br />HUC 1408 - Two populations of bluehead and tlannelmouth sucker, one population of roundtail <br />chub. Knowledge of status in this unit is relatively limited. Bluehead and.tlannelmouth sucker are <br />both regularly observed in the mainstem San Juan. In the San Juan River drainage, roundtail chub <br />currently only occupy upstream tributaries in Colorado. No fish were observed in Montezuma Creek <br />in 2005. Other tributaries in the San Juan drainage were de-watered or have not been surveyed by the <br />Division; therefore, status is unknown in most of these locations at this time. <br /> <br />HUC 1501 - Three populations of tlannelmouth sucker. Flannelmouth sucker are currently found in <br />all historical localities in the Virgin River system: Virgin River mainstem, East Fork Virgin River, <br />and North Fork Virgin River. <br /> <br />HUC 1601 - One population of bluehead sucker. Bluehead sucker are considered not present in <br />surveyed localities in the Bear River. system. <br /> <br />HUC 1602 - Three populations of bluehead sucker. Bluehead sucker are considered historically <br />present in the Ogden River, the South Fork of the Ogden, and the Weber River and Mill Creek. <br />Bluehead have only been found recently in a small portion of the Weber River and are thus <br />considered quite rare in this system. <br /> <br />Progress toward achieving the overall goal will be used to evaluate effectiveness -. have we <br />established or maintained the designated number of populations in each management unit? If one <br />population is lost, the Team can choose to re-establish this population using a nearest neighbor <br />population, any genetically appropriate population, or a highly robust and healthy population either <br />in the same location or in a different stream within the unit or state. Weare currently considering the <br />need for a hatchery or grow-out facilities only for bluehead sucker in the Bonneville Basin; however, <br />three species cooperators may eventually decide these options are a necessity for all three species.
