Other existing reservoirs and ditches on the project's <br />watershed have only minor effect on decreasing flood peaks. Due to topography, <br />general aspect, and past flood history of the watershed, the construction of <br />large flood control structures is not recommended. Improved management and <br />use of watershed lands, plus related measures such as fencing, revegetation <br />and small structure will yield better and longer-lasting resul ts. <br />- 54 - <br />
