Early June Report
6/10/19 @ 8:00 a.m. -- Water levels on Chowen Ave. have gone down significantly over the past week.
6/5/19 @ 1:42 p.m. - Public Works has a larger (quieter) generator set up and pumping. They will be pumping 24/7 from Crystal Lake and carefully monitoring water levels of Twin Lake and Ryan Lake.
6/5/19 @ 12:40 p.m. - Our Public Works staff is working with a Contractor to set up a better pump to continue removing water from Crystal Lake. To reduce the set up down time with the conversion to the new pump, the discharge hoses from this new pump will be running above ground for now.
Drew Avenue and Ewing Avenue will be closed to through traffic at County Road 9, although residents living in this neighborhood will still have access via 46th Avenue and through the alleys.
The driveway entrance from County Road 9 into the Peace Lutheran Church parking lot will be closed.
5/31/19 @ 11:10 a.m. - Update on Crystal Lake & Standing water @Chowen Avenue. Hennepin County Emergency Management is helping to set up a pump today (the contractor we expected to be on site yesterday needs until next week to mobilize.) We have been preparing for the pump installation for the contractor and a different set up with Hennepin County yesterday and today. The storm water pipe in Chowen Avenue is full of water; below lake level. The water in the street at the dip in the road is at lake level.
We tested the impact of pumping a truck of water. It took the street water level down about 8 inches on the pavement (marked with rocks) and about 1/4" depth. The water came back up in less than 5 minutes.
We are concentrating our efforts on the big pump set up, while watching the lake level impact through Ryan Lake. We'll check back later today.
With hot windy weather, there should be a positive evaporation impact on the lake level and ponding today.
