Higgins Lake Water Quality Sampling – 2018:
The Higgins Lake Property Owners Association (HLPOA) approached Raven Analytical Laboratory in Roscommon, MI to provide water sample testing on Higgins Lake in January of 2018. This project would not have been a success without being generously supported by The Higgins Lake Foundation, The Higgins Lake Property Owners Association, the Roscommon Rotary Club and by John Ogren, a Roscommon High School Graduate and HLPOA Board Member.
This updated report by Raven Analytical Laboratories covers all four water testing cycles in 2018 on Higgins Lake: May 16-18, June 15-17, July 18-20 and October 22-24:
Near Shore Water/Algae Testing – 2016:
A preliminary study to document the benthic algal community and associated levels of phosphorus (ortho-phosphate) and nitrogen (nitrate-nitrogen and ammonia-N) in the littoral (i.e.: near shore) zone of Higgins Lake was performed in 2016 by Dr’s Rex Lowe and Pat Kociolek, of the Univ. of Michigan Biological Station (UMBS). The link below contains their report. It is a desire of the Environmental Committee to have Dr. Lowe perform future studies to document trends, thereby allowing further analyses and/or potential corrective actions.
Higgins Lake Water Quality Study of 1995-99 by the USGS:
A 2001 report by Russel J Minnerick of the Lansing office of the U.S. Geological Survey (USGS) looked at the effects of residential building on the water quality of Higgins Lake. His work covered the years of 1995 to 1999. The entire report may be read by clicking on the link below the next paragraph.
There is a wealth of information contained in this report for those readers who are technically oriented. The scientifically obtained water quality data and accompanying analyses contained therein serves as the “Gold Standard” of baseline data to be used for future Higgins Lake water quality studies in the years to come. A key excerpt from his summary is: “Ground water beneath the lake showed higher concentrations of phosphorus, nitrogen, chloride and boron than lake water samples. Escheria coliform (e. coli) bacteria was found in sites where building density exceeded 0.4 buildings per acre, indicating that water from septic systems is leaching into the ground water that flows into the lake.”
Higgins Lake Water Quality Study of 1998:
The link, below, is to a “1998 Water Quality and Bottom Sediment Study” performed by Water Quality Investigators of Dexter, MI. This study serves as a baseline for water and sediment quality and its discussion/conclusions are presented in more of a layman’s style for ease of understanding. A number of geographical errors can be found on the first page. The HLPOA’s Environmental Committee Chair has taken the liberty of inserting an errata sheet immediately following the first page using more accurate information for your reference.
