  • Legal Recourse to Address Lakewood Shores Drain Impact - During the fall of 2008 and winter of 2008/2009 we researched with our lawyer and the DEQ the potential possibility of legal action and the probable outcome of such action to address the lake level lowering unintended consequence of the Lakewood Shores Drainage System.  Attached is a document that summarizes our meeting with the DEQ REGARDING CEDAR LAKE WATER LEVELS LOWERED BY THE LAKEWOOD SHORES DRAIN  and the following is the legal opinion of our attorney News/AICLA - Cliff Bloom Opinion on Sueing the Drain Commissioner.pdf
  • Evaluation of Alcona County Proposed Repairs to the Timberlakes Subdivision Drainage System - In early December 2007 the association board became aware of planned work by the Alcona County Road Commission to effect a drain-off of excess spring groundwater in Timberlake's subdivision.  While we were assured by Greenbush township that this work is minimal, necessary for the wellbeing of Timberlake's residents, and not expected to cause the lake further water level problems, the similarity of the problem and solution so closely tracks with Lakewood Shores POA back in the 90's, that flags were raised with us.  While we had no  reason to believe that this would even be a problem, let alone one of the magnitude of the Lakewood Shores POA project (40% of our water loss every year is an unintended consequence of the "fix" of the Lakewood Shores problem), we were not leaving anything to chance.  Kieser & Associates was contracted using "Save the Lake" funds to assist in an investigation of the impact of the solution planned for implementation in the spring.

    Kieser has completed their work.  Click on LakeInformation/AICLA - Timberlakes Drainage Repairs - Kieser Report.pdf to read the complete Kieser report.

    Basically, Kieser finds that this particular repair should not affect our water level.  However, they do warn us that, should an effort ever be considered to completely restore the Timberlakes drainage system to its full functioning condition, there will be added water level losses experienced on Cedar Lake.

  •  Hydrological Evaluation of Cedar Lake - In 2004 the lake association embarked on an effort to determine the reasons for dramatic drops in lake water level every summer.   A lake that starts the spring overflowing at the dam, and averages less then five feet deep, experiences water level drops of up to two feet or more by September every year.  Kieser & Associates, an environmental science and engineering firm out of Kalamazoo Michigan was contracted to study the matter.  Over a two year period the lake was monitored and researched.  All sources of water coming into the lake were analyzed, as were all the various ways for water to leave the lake.  Kieser's work was completed in two phases and is documented in the following studies: Final Report - Phase I_7-15-05.pdf and images/AICLA - Kieser Final Report Phase II 9-15-06.pdf
  • Piezometers - Part of the Kieser study was to monitor ground water flowing into and out of the lake.  This is done by sinking pipes (piezometers) located strategically along the shoreline at various places.  Quite simply, if water is higher in the pipe then the lake level, then ground water is flowing into the lake.  If water in the pipes is lower then the lake level, then water is flowing out of the lake.  The well pipes were monitored throughout the study period by volunteers from the association.  The pipes will remain in place and will continue to be monitored to provide continuous information regarding ground water movement.  This will become extremely important as the association takes action to correct the water level problems.  The pipes will be a means to measure the effectiveness of actions taken.  The location of the piezometers and names of the volunteers monitoring them are depicted on the following map; LakeInformation/Piezometer Locations - Volunteers Winter 2008-09.psd
