Page 51 to three species populations at this time; however, three species cooperators will work to reduce threats in one of these tributaries ar another one based on updated information. ~ HUC 1405 -One population of each species. Flannelmouth and bluehead sucker are considered abundant in the White River, though roundtail chub is considered rare. Maintenance of these populations will be considered success in this drainage. HUC 1406 -Twelve populations each of bluehead and flannelmouth sucker, seven populations ~ of roundtail chub. Bluehead sucker are known to currently be present in the Green, Duchesne, Strawberry, and Price rivers and in Ashley, Cottonwood, Huntington, Ferron, and Red creeks. They are either not present or status is unknown in the following: Uinta, Lake Fork, and San Rafael rivers and Avintaquin and Currant creeks. Flannelmouth sucker distribution is similar except that they are moderately abundant in Avintaquin Creek, rare in the San Rafael, and not ~ present in Huntington Creek. Distribution of the roundtail chub within this unit is more restricted. They are rare or moderately abundant in the Green, San Rafael, and Duchesne rivers and not present (or status unknown} in the remaining streams recently surveyed. HUC 1407 -Nine populations of bluehead sucker, six populations of flannelmouth sucker, and r three populations of roundtail chub. Bluehead sucker are present in Ivie, Quitchupah, Pine, and Mamie creeks and the Fremont, Escalante, and Colorado (above Lake Powell) rivers. They were not found during Muddy Creek surveys during 2005 and their status is unknown in the Dirty Devil River. Flannelmouth sucker are present in the Colorado River above Lake Powell, the Escalante and Fremont rivers, and in Ivie and Sand creeks. They are considered not present or ~ status unknown in the Dirty Devil River and Muddy and Quitchupah creeks. Roundtail chub are present, but rare in the Colorado River mainstem above Lake Powell and the Escalante River. They have not been observed in recent surveys in the Dirty Devil River or the Muddy Creek drainage. . HUC 1408 -Two populations of bluehead and flannelmouth sucker, one population of roundtail chub. Knowledge of status in this unit is relatively limited. Bluehead and flannelmouth sucker are both regularly observed in the mainstem San Juan. In the San Juan River drainage, roundtail chub currently only occupy upstream tributaries in Colorado. No fish were observed in Montezuma Creek in 2005. Other tributaries in the San Juan drainage were de-watered or have not been surveyed by the Division; therefore, status is unknown in most of these locations at this ~ time. HUC 1501 -Three populations of flannelmouth sucker. Flannelmouth sucker are currently found in all historical localities in the Virgin River system: Virgin River mainstem, East Fork Virgin River, and North Fork Virgin River. HUC 1601 -One population of bluehead sucker. Bluehead sucker are considered not present in surveyed localities in the Bear River system. HUC 1602 -Three populations of bluehead sucker. Bluehead sucker are considered historically ~ present in the Ogden River, the South Fork of the Ogden, and the Weber River and Mill Creek. Bluehead have only been found recently in a small portion of the Weber River and are thus considered quite rare in this system.
