S.wcrson s^d this is site specific and depends on faas such as erosion and d^ elopment, w increase^he amount of cleaning done. Syverson sdd the Orono project is r--cell Jhe first cell would catch the most sediment and need to be cleaned out m • larger cell would require less fi-equeat cleaning projected at 15-^0 years. e ® is dependent upon the management practices upstream. Hwy U consmicnon w^ ci« ™pie. If silt fencing wVe not done on the ponds there, more matenal would faU into th * ponds requiring frequent cleaning. Sy\erson said the management is cooperative effort. Lindquist inquired about the Dickey Lake arei Syverson noted this y = * '"'J' ohosphotus loading area and the cost would not justify a pond.
