Lake Manager’s Report – June 2017

1. The MPOA dredging contractor re-mobilized and completed Wickline Island. They then re-positioned and began dredging at O’Brien Shoals. They were able to complete the area shown in red below, before encountering thick deposits of rock “cobble”, ranging from golf-ball to tennis-ball size. The dredging of this cobble caused the larger on-shore booster pump to break down, leading to a dredging work stoppage of approximately 11 days until a replacement booster pump could be located and brought in.

Lake Manager’s Report – May 2017

1. The MPOA dredging contractor has re-mobilized, and based on field observations today, it would appear that the Wickline Island dredging should now be complete.

Lake Manager’s Report – April 2017

1. The MPOA dredging contractor has re-mobilized, and is continuing to get the equipment and dredge pipeline ready for the start of the 2017 dredging season. Dredging is expected to get underway within the next week.

2. The dredging contractor has indicated that they will first resume work at Wickline Island first so that area can be fully completed. The area remaining to be dredged at Wickline Island is shown below:

Lake Manager’s Report – March 2017

1. The dredging contractor is making plans to re-mobilize for the 2017 dredging season around the first week of April. The working plan is to first complete the remaining dredging of O’Brien Shoals and Wickline Island, before moving to the South Bay prior to the Memorial Day Holiday, if not sooner. Obviously, the weather at this time of year is still a factor, as below freezing temperatures can be an issue with the pumps and equipment.

Lake Manager’s Report – February 2017

1. After the lake iced-up in December, a question arose as to the possible presence of dredging pipeline still extending across the main body of the lake. Further investigation determined that while the vast majority of the dredge pipeline had been removed from the lake, or was moved to the northwest area of West Bay, a section of pipeline at the summer 2016 pipeline crossing was still in place. This crossing location is still marked by “no-wake” buoys, and all sections of this pipeline segment are fully submerged below the ice / lake level.

Lake Manager’s Report – December 2016

  1. After moving out of South Bay, the dredging contractor began work at Wickline Island, and was able to complete the areas shown in red below before having to shut down for the winter on November 22.  Dredging this area took longer than expected due to encountering primarily clay lakebed, which clogs the dredge cutterhead, instead of the expected softer sediments.

Lake Manager’s Report - November 2016

  1. The MPOA dredging contractor has moved out of South Bay and has begun work at Wickline Island.  As of the start of this week, they had completed the area northeast of Wickline Island (as shown in red below) and were moving around to work on the southeast and east side.

Lake Manager’s Report – October 2016

1. The MPOA dredging contractor will be moving out of South Bay MPOA by next week to work on completing the Wickline Island dredging before moving up to resume work on the O’Brien Shoals area. Any remaining Lake User’s need to be aware of changing conditions related to the location of the dredge, anchor barges, booster pump, and sediment pipeline. Any remaining areas to be dredged will be completed in 2017.

Lake Manager’s Report – September 2016

1. The MPOA initiated a “no-wake” zone in the southern part of South Bay, as displayed below and on the MPOA website. The northern edge of the no-wake area has been marked with buoys), but lake users are again reminded that the entire area of the lake south of that is now no-wake.

2. The no-wake condition also extends to any area within 100 feet of the dredge, anchor barges, booster pump, and pipeline. This no-wake condition will remain in place until dredging of South Bay has been completed.

Lake Manager’s Report – July 2016

1. The MPOA has received numerous comments from lake users about issues in their trying to cross the sediment pipeline at the designated crossing point. The MPOA continues to work with the dredging contractor to make sure that lake users understand how to cross the pipeline without damaging their boats or the pipeline.

Lake Manager’s Report -June 2016

1. The Nippersink Watershed Association (NWA), received a donation of almost 200 potted plants from the U.S. Fish and Wildlife Service intended to provide butterfly and pollinator habitat. On June 4th, Mark Nichols and the Wonder Lake Sportsman’s Club coordinated the planting of roughly 150 of these plants on Strom Island, with the following volunteers participating.

Lake Manager’s Report – May 2016

The Wonder Lake Sportsman’s Club held its annual lake clean-up on April 17th.   Be sure to thank the following folks for their much appreciated efforts:

Lake Manager’s Report – April 2016

  1. In August 2015, the Nippersink Watershed Association (NWA) applied for water quality improvement grants for $ 1.7 million in projects.  All of these projects are located upstream of, or in, Wonder Lake.  The NWA has been notified that these grants have been approved, with the Illinois Environmental Protection Agency (IEPA) granting almost $848,000 in Section 319 funds.  This IEPA amount represents almost 25% of the Section 319 funds IEPA awarded state-wide in this grant cycle.  I will be meeting with those folks receiving grants, once I get more information from IEPA.

Lake Managers Report – February 2016

1. I am still working with our dredging consultant to obtain the surveyed sediment verification for White Oaks Bay so that the MPOA can finally confirm that the volume of dredged sediment for WOB, as required under the dredging contract has been removed from that area.

2. The MPOA dredging contractor has de-mobilized for the winter. All dredging equipment / pipeline that will remain in the lake over the winter has been relocated to West Bay, as shown below. Winter lake users will need to exercise caution when in West Bay.

Lake Manager’s Report – December 2015

1.    The MPOA dredging contractor is continuing to de-mobilize for the winter.  All dredging equipment / pipeline that will remain in the lake over the winter has been relocated to West Bay, as shown below. Assuming the lake will eventually ice over, winter lake users will need to exercise caution when in West Bay.  

Lake Manager’s Report – November 2015

1.    The MPOA dredging contractor continues to work on the O’Brien Shoals area.  The following exhibit shows the approximate extent of the dredging conducted to date in that area.  
2.    The dredging contractor has indicated that they intend to work as long as temperatures allow this fall. Typically, this may be up to the end of November.

Lake Manager’s Report – October 2015

1. The MPOA dredging contractor has completed the dredging of White Oaks Bay, and has re-positioned the dredge and pipeline to allow them to begin dredging near O'Brien Shoals. This means that the pipeline is now extended across the middle of Wonder Lake, roughly between West Bay and Wonder Center Beach. While the dredging contractor has installed pipeline markers and pipeline crossings, all lake user's must exercise extreme caution when operating in the mid-section of the lake.

Lake Manager’s Report – March 2015

1. The MPOA has received the “Aquatic Invaders” signs to be posted at all WL boat ramps. The Wonder Lake Sportsman’s Club (WLSC) has agreed to the install the signs as part of their Spring 2015 annual lake cleanup. The signs will be installed on “T” posts or existing fences near each boat ramps. If any subdivision does NOT want the sign installed, contact the MPOA office.

2. The WLSC Spring Clean-up will be scheduled for mid-to-late April. A definite date should be available for the next MPOA meeting. Volunteers are always welcome.

Lake Manager’s Report – February 2015

1. In cooperation with the Wonder Lake Sportsmans Club (WLSC), the MPOA again applied for a SCALE grant from IEPA to offset the costs of the annual spring lake clean-up conducted by the WLSC. This grant was approved, which will provide $ 500 in funding to WLSC. As always, volunteer’s are always welcome for the lake clean-up. Details on the 2015 clean-up will be provided when a date is determined.

Lake Manager’s Report – January 2015

Agenda Item V.E. - January 8th, 2015

1. The SDF was dewatered for the winter. This will help consolidate the sediment already present in Cell # 1; allow the MPOA to make any necessary inspections; and will allow for any minor maintenance that may be required in the spring, before dredging resumes.

Lake Manager's Report - December 2014

1.    The dredging contractor has completed their winter shut down.

2.    Winter lake users are cautioned that the sediment pipeline used in the dredging project will remain in place in teh West Bay over the winter. While much of the pipeline will be submerged below or barely protrude above the ice surface, the dredging contractor has marked the pipeline alignment.

3.    The dredging contractor has provided an exhibit (below) showing the approximate location of the equipment left in West Bay for the winter.

Lake Manager’s Report – November 2014

1.    Dredging for the 2014 construction season ended on November 11, 2014.  The early on-set of sub-freezing weather was beginning to impact mechanical parts on the dredge and booster pump, resulting in the need to shut down operations.  They will be spending next week doing a partial demobilization of the equipment, all of which will remain on-site over the winter, so they can resume work as soon as weather / lake conditions allow in Spring 2015.

Lake Manager’s Report – October 2014

  • The dredging continues.  As the dredging of the Nippersink inlet is the slowest and most challenging part of the overall dredging project, as well as being hardest on the equipment, the dredging contractor is still indicating that they hope to  complete the rest of the Nippersink Creek inlet work before they shut down for the winter.

Lake Manager’s Report – September, 2014

1. The dredging continues. As expected, while working on the Nippersink Creek inlet, the contractor was encountering a large volume of rock, as this is the first material that settles out and accumulates after being washed into the lake by the Nippersink. While the dredge can pass rocks up to “baseball” size, some odd shaped rocks got past the screen and bent a part on the booster pump, causing some delays while replacement parts were obtained and installed. The contractor has also installed an additional screen to further block rocks from entering the dredge pipe.

Lake Manager’s Report – July, 2014

1. The SDF contractor has completed all of the remaining punch-list items, barring some final site clean-up, and I am working on closing out their contract over the next month or so.

2. Dredging officially started at 1:30 pm on June 25th.

Lake Manager’s Report – June, 2014

1.    The SDF contractor is working on completing the “punch-list” items resulting from the May 14th, 2014 walk-through of the SDF site, which included the HDR project engineer; the MPOA dredging consultant; and the SDF contractor. The SDF contractor is aware that the SDF perimeter safety fencing is their short-term priority, and needs to be fully in place before the dredging can commence.  Other SDF punch-list items can continue after dredging has commenced.

Lake Manager’s Report – May, 2014

1.    A site walk-through of the SDF site was conducted on May 14, including the HDR project engineer; the MPOA dredging consultant; and the SDF contractor.  The SDF is coming along well, with the slopes greening up, and the perimeter fencing work underway.  A punchlist is being developed that will identify items the SDF contractor still needs to address to fulfill their contract requirements.

Lake Manager’s Report – March - April, 2014

1.    The SDF contractor is estimating final project completion by around May 1st, 2014 (weather permitting), which will allow a 2014 dredging start.  Recent aerial photos of the SDF site, taken by Bob Schell, are posted on the MPOA website.

Lake Manager's Report — February 12, 2014

1.    The SDF contractor is still estimating final project completion by April 1st, 2014 (weather permitting), which will allow a 2014 dredging start.
2.    Requests for dredging bids were sent to eight (8) firms known to have worked on similar sized projects.  One of these firms, based on the East Coast, and who had previously expressed interest in our project, has indicated they will not be bidding.  Other prospective bidders have submitted a number of questions regarding the project / bids, and two firms have conducted site visits to date.

Lake Manager’s Report – January 8th, 2014

1.    The SDF contractor began pouring the foundations for the two SDF water control structures before the weather deteriorated.  SDF site work is on hold for the foreseeable future.
2.    Soil borings to confirm that the constructed SDF liner is compliant with the IEPA permit requirements have been conducted.  Review of the laboratory testing results of the collected soil samples is currently underway.
3.    The SDF contractor is still estimating final project completion by April 1st, 2014 (weather permitting), which will allow a 2014 dredging start.
