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:

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.

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.
   

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.

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.

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:

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.

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.  

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.

1. The “Preliminary Dredging Sequence and Timeline” is being posted / updated on the MPOA website as we get new info. This sequence and timeline will likely shift as dredging continues, based on equipment issues, temperatures, flood events, and other unforeseen circumstances. Those already on the MPOA e-mail mailing list will be notified when updates are posted to the MPOA website. If you are not on the mailing list, contact Lance at the MPOA office at: office@wlmpoa.org.

1. Because of changes in MPOA office staffing, and to accommodate the scheduled availability of new workers for the decal sales, the MPOA office hours have been changed. The new Summer hours for the MPOA office are from Tuesday through Friday from the hours of 10 am to 2 pm. Saturday hours are from 8 am to 1 pm.

2. As we have new office staff handling the decal transactions, in advance we ask for your patience and cooperation, and offer the following suggestions:

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.

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.

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.

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.

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.

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.

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.
