Minutes of Regular Councl I Meeting Page four -. June 25, 1984 used, and It Is noisy - will be hea~d 24 hrs/day; noted that the alternative would be service from NSP, which could be a 6-week walt. A resident said their spokesman Is not here yet; he has Information relative to the high and low water levels of the lake; residents consider the pumping a short-term solution to save some of their property; are looking for a long-term solution to maintain lake at a certain level - a level we can all agree upon. Christoffersen advised that the DNR wi II establish the level; residents wi II not have that option. Keith Enrooth (spokesman for the Karth Lake residents) arrived at the meeting, and Christoffersen summarized the lake level and pumping data given earlier In the meeting. Johansen referred Councl I to estimated pump costs obtained from three companies; noted they are rough estimates, nothing concrete- were obtained over the phone; stated the costs would probably not exceed the maximums quoted. . In answer to a resident's question as to the location of the pump- Ing site, Christoffersen Indicated the anticipated pumping loca- tion on Karth Lake Drive, from which the lake water would be discharged Into the gutters at a rate of 1000 gpm to the nearest catch basins; noted the water wi II be running down the street ~4 hrs/day; generator noise will be heard 24 hrs/day for about 8 days, If lake Is to be lowered li-2 feet. Christoffersen traced the route of the water from the Karth Lake Drive location to Its eventual discharge Into Rice Creek. Some of the concerns expressed by residents present were: - anticipated run-off from Lexington Avenue Improvement; will It Increase over what It was before? - anticipated run-off from Hamllne Avenue when road Is up- graded? - why doesn't Kar~ Lake have an outlet? - some of the riparian landowners now have portions of their previously dry land under water. ~ - trees are in Jeopardy. Christoffersen responded to the run-off questions; explained the storm drainage routes northwest and south of the Karth Lake District which Is through storm sewers and then via surface drainage north to Marsden Lake and Rice Creek - west across Hamllne and then surface drainage to Round Lake, south to County Road F ~ and then surface drainage to Valentine Lake. Christoffersen explained that the Karth Lake District drains Into Karth Lake which Is an Isolated body of water that does not have a direct outlet. Christoffersen explained that a direct outlet for Karth Lake was not anticipated because the storage capacity of the lake was con- sidered to be sufficient to store all of the drainage from Its relatively small tributary area; noted that a 100 year storm could bring It upA4"; reported that the trees were not taken Into con- sideration, only the houses. Christoffersen explained that lake level control can be achieved by Installing a storm water pumping station and forcemaln which would discharge flows Into Marsden Lake District; this permanent . outlet would probably Involve an area assessment and approval by DNR. Enrooth ~eported that the matter of assessment was discussed at their meeting; some agreed to an assessment and others did not - feel they are already paying high taxes. Rauenhorst moved, seconded by Mulcahy, that Councl I authorize the pumping of Karth Lake, lowering the lake level 18" at a cost not to exceed $4,000.
