Creek, No Name Creek, and a portion of Meadow Creek, performed by Robillard and Associates, Inc., Dillon, Colorado. , ~. On June 18 and 19, 1990, initial Consultation and Coordination Officer (CCO) meetings were held with representatives of FEMA, Summit County, the Town of Frisco, the Colorado Water Conservation Board, and the study contractor. At this meeting, the streams requiring detailed study were identified. An intermediate CCO meeting was held on September 23, 1992, to present the preliminary results of this revision. This meeting was attended by representatives of FEMA, Summit County, the Town of Frisco, the Colorado Water Conservation Board, and the study contractor. On November 15, 1993, the results of this restudy were reviewed at a final CCO meeting attended by representatives of the Town of Frisco, Summit County, the Colorado Water Conservation Board, FEMA, and the study contractor. Streams studied by detailed and approximate methods and their limits of study are listed in Table 4. The Upper Blue River Basin begins at the Continental Divide, bounded by Hoosier Ridge to the south. The basin has a drainage area of 129 square miles and drains to the north along the Blue River to Dillon Reservoir. The Blue River channel slope varies from 4.6 percent above Breckenridge to 1.2 percent above Lake Dillon. Study reaches within this basin include two stretches along the Blue River and portions of three tributaries of the Blue River, which are French Gulch, South Barton Gulch, and Swan River~ ~ The Snake River Basin forms the easternmost section of the Blue River Basin. The Snake River Basin drains in a westerly direction, from an elevation of 14,270 feet at Grays Peak along the Continental Divide south of Loveland Pass, to Dillon Reservoir at an elevation of 9,000 feet. The basin is approximately 7 miles wide throughout and 12 miles long with a drainage area of 76 square miles at Dillon Reservoir. The channel slope ranges from 5.7 percent in the upper basin above the Town of Montezuma to 1.1 percent in the study reach near Keystone Ski Area. The study reaches within the Snake River Basin include a portion of the North Fork of the Snake River and a portion of the Snake River near Keystone. The Tenmile Creek Basin drains to the north, then northeast into Lake Dillon from the Fremont Pass vicinity. This basin parallels the Upper Blue River basin with the Tenmile Range dividing the two. The western boundary of the basin is formed by the Gore Range and Vail Pass, and the southern boundary is the Continental Divide. The upper basin is characterized by an open rolling terrain. In contrast, the lower basin consists of the narrOw winding Tenmile Canyon. The total drainage area is 94 square miles at Frisco, with 35 square miles lying in the upper basin 29
