SPECIAL LASE ELMO COUNCIL MEETING, MAY 119 1983 -2- LAKE J OE FLOODING- Continued - --Eder - District's contingency plan oal]#+for augmenting a deisel pump for emergency situations - this should be -put into effect rather then implementing this suggestion, --Nelson - resident(s) have expressed strong feelings about the diesel pump (against the noise) --Morgan - should do both measures - may damage vegetation, but this is not a threatening situation, Get pump in post-haste to level off Jane, --Gunnar Guidlow - asked about possible storage on upstream latices such as Long or Silver. Also, questioned the holding capacity of City Park Pond. --Nelson - City Park Pond is well below capacity. Chuck Taylor cited present water level and past levels and capacity using the deisel pump. --Nelson - restricting outlet from Long Lake would have little effect, --Taylor - thistime of ,year run-off from Grant Township is significant and increases with every rain. Should check impact from this area. --Ken Sovereign, Olson Lake Tr. N, - Valley Branch has chosen pumping as the means of fretting the water out of Jane - if this means using a larger pump then that what they should do. Disagrees with Engineer Nelson's statement that Olson and. Jane will not flood witl a 6!1�rai.n - f4e1 this was settled as a settlement to a, Lawsuit - appears that if any flooding results from slowing down the natural flow of the water or the judicial flow, which this is, of the water you, have a lawsuit pending. If Valley Branch can keep the level, there is no rain and no flooding nothing will happen. If there is rain and flooding and the pump cannot handle it now, then it cannot handle later. Should check two things- 1. Citys liability if slow drnm the weir 2. VBWD' liability in not installing a. pump large enough to handle capacity. --Nels Nelsen - responded to question from Scotty Lyall concerning drainage from Castle Green. This situation is a concern., but not solely responsible for the flooding on Jane. Also, in response to Mr, Evanoff's question, the District has not made a decision on starting the pump earlier. --Bder - District needs City approval to place sandbags on the weir because the City is the owner of the weir and any alteration of the weir requires City permission as well as DNR approval - City has to decide whether to allow this action by VBWD or not. The weir, its construction and elevation level was a settlement of a lawsuit, with township funds invested in the weir. --Ray Marshall, City Attorney - not familiar with this suit. Would like to review file before making determination as to the settlement stipulations. MVS/ Morgan/Dunn that the City of Lake Elmo strongly urge the Valley Branch Watershed District to install a larger diesel pump (4 cis), on Lake Jane with the capacity to meet the inflow of water into Lake Jane; and, in the interim, until the pump can catch up with the inflow and control the flooding, that the present level of Lakes Olson and Demontreville be maintained by sandbagging the Olson Lake Weir. The level of maintenance shall be the level determined on May 11, 1983, by VBWD. Maximum maintenance time not to exceed two weeks, at this level. The levels on Lakes Olson and Demontreville cannot rise or the sandbages will have to be removed immediately.
