I I I Council Meeting Minutes October 22t 1985 Phyllis Rehat Chairperson of the EQCt stated her Commission would be glad to look at the issue if council so directed. (Note: The council did not so direct.) Harcus asked if the large amount of rain contributed to the soft water results of the test; Laing stated the water is soft because of the rain but didn't know if the lake water was soft all year aroundt adding that rain water is usually loaded with ammonia, phosphorous, and carbon dioxide which would not cause a good chemical rating of the lake. David Hoel. 2738 17th Terrace N.W.t stated Lake Diane is like a river as it has water flowing in at three locations and one overflow; asked how Clean-Flo's process affected a lake rather than a pond. Laing responded the more flushing there is. the harder it is to control. but noted sand was now found around the shoreline. Hoel stated another concern is the bog and asked if the process could be hastened to remove it in a shorter amount of time; Laing stated it would gradually disappear and that to dredge it would be the only way to speed it up. In response to Benke's comment concerning relocating the aerators around the bog during the winter months to accelerate the removal of the bog and to have the open water area moved to another location. Laing responded that in the first year or two there are not many changes. but then, as bottom-feeding organisms become more and more establishedt there will be an acceleration in decline. Allen Cox, 1842 - 26th Avenue N.W., stated that when he agreed to participate in this project water quality was not an issue, the prime issue was to get rid of the bogs. Cox feels it is futile to use chemical treatment because the lake is a watershed with water draining through it; suggested using a high-pressure water hose to physically break up the bog to increase the surface area, giving the aeration system more surface on which to work. To reduce the sost of the project, Cox suggested turning off the system during the winter months to save the cost of fencing around the air holes and, in addition, eliminate the chemicals and insurance. Cox then suggested the possibility of working with the city to put up the fencing. Laing responded that the elimination of the bog is directly related to water quality and that the breaking up the bog is a good idea but indicated Clean-Flo would not get involved in that process because the DNR has permitting requirements. Harcus questioned the DNR's control of bogs; Phyllis Reha. chairperson of the Environmental Quality Commission, stated the DNR has juris- diction over public water and a permit is required to make any improve- ments.
