<br />Fountain Creek at the upsteam oorporate limit (undisturbed by <br />Highway 24), at an elevation of 5,400 feet, has a channel width of 10 <br />feet. Pea-size gravel deposi ts~ tree scaring, and grass covered <br />banks, indicate recent flows have not exceeded 3 feet. Therefore <br />recent streamflow of 300 cubio feet per second is indicated. <br />At an elevation of 5,700 feet, on the right bank of Fountain <br />Creek, is a 5-foot deep and 30-foot long gravel flood bar that was <br />deposited in the last 100 years. The flood bar contains boulders of <br />up to 2 feet in diameter. Because of the highway is is unknown how <br />wide the channel was during the deposition of the flood bar. <br />The recent channel has the same dimensions as at the previous <br />location. <br />Waldo Canyon joins Fountain Creek at an elevation of 6,750 feet <br />and has an approximate drainage area o~ 2 square miles. A private <br />road is located in the canyon (owners were not at home and upstream <br />investigations on private property were not made). However, channel <br />dimensions by Highway 24 are: width is 5 feet and the depth is 2 feet. <br />The peak discharge for recent flows would be about 100 cubic feet per <br />second. <br />French Creek joins Fountain Creek at an elevation of 7,220 feet <br />and has a drainage area estimated to be about 5 square miles. There <br />are no significant flood deposits in the channel. The channel width <br />is 4 feet and the banks are grass and moss covered to about 2 feet <br />above the streambed. There is no flood debris above this depth. This <br />would indicate that recent peak discharges have not exceeded 100 to <br />200 cubic feet per second. This lack of flood evidence indicates that <br />flows have not exceeded the erosion threshold discharge of 200 to 300 <br />cubic feet per second for 100 years or more. Just downstream from <br />French Creek, Fountain Creek channel dimensions are 1~ feet wide and 2 <br />feet deep. The peak discharge of recent flows is estimated to be 200 <br />oubic feet per second. <br />Cascade Creek joins Fountain Creek at Cascade at an elevation of <br />7,350 feet and has an estimated drainage area of 9 square miles. <br />There are no flood deposits in the channel. The channel width is 4 <br />feet and moss and lichen completely cover channel boulders to the <br />water surface about 1 foot above the streambed. This channel suggests <br />that recent peak discharges are less than 40 cubic feet per second. <br />This lack of fl~od evidence indicates that flows have not exceeded the <br />erosion threshold discharge of 200 to 300 cubic feet per second for <br />100 years or more. <br />The unnamed left bank tributary to Fountain Creek at Casoade at <br />an elevation of 7,360 feet has an estimated drainage area of 1 square <br />mile. The channel is a 3-foot wide swale and is completely grass <br />filled showing no evidence of flood deposits. This channel suggests <br />recent streamflow has been less than 30 cubic feet per second. This <br />lack of flood evidence indicates that flows have not exceeded the <br />erosion threshold discharge of 200 to 300 cubic feet per second for <br />100 years or more. <br />The channel dimensions of Fountain Creek at Cascade are: width is <br />8 feet and depth is 2 feet. There are no significant flood deposits <br />and the banks are well vegetated with grass, brush, and moss. The <br /> <br />Ie <br />
