An aerial view of Cherry Creek between <br />Lakewood Gulch and Franktown. April 1969. <br /> <br />c. From Cherry Creek Dam to Goldsmith Gulch, a distance of <br />about 4 miles, the channel is ~enerally in its natural state. <br />From the dam to Havana Street, the channel was improved durinp- <br />the construction of the Cherry Creek Dam and Reservoir. From <br />Havana Street to Goldsmith Gulch, the channel is sinuous and <br />ran~es from 50 to 150 feet wide and from 2 to 10 feet deep. <br />Channel capacity in this reach avera~es 4,000 cubic feet per <br />second. Loss of floodway capacity has resulted from indis- <br />criminate filling of overbank and channel areas by landowners. <br />In addition, channel materials can be eroded by sustained <br />releases from the Cherry Creek Reservoir. ~o drop structures <br />have been constructed in this reach to control channel erosion. <br /> <br />d. Between Goldsmith Gulch and Speer Boulevard, a distance <br />of about 5 miles, the Cherry Creek channel has been improved by <br />local interests. The channel is about 80 feet wide and 10 feet <br />deep in this reach and has an average slope of 25 feet per mile. <br />Its capacity is about 14,000 cubic feet per second.
