Fifty <br />of the districts submitted inventories giving a total of <br />6,009 (bank mi les) of moderate erosion and 6,962 (bank <br />mi les) of severe erosion for a total of 12,971 (bank mi les). <br />Twenty-nine of the districts nominated 1,278 (bank mi les) of <br />streams to be studied. The 10 streams chosen to be studied <br />had a total of 402 (bank mi les) or a total of 201 stream <br />mi les. The actual stream mi les studied for the 10 study <br />areas was 62.31. <br /> <br />~ <br /> <br />I <br />'"', <br />. <br /> <br />37 <br />
