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 member.
This updated report by Raven Analytical Laboratories covers all three water testing cycles in 2018 on Higgins Lake: May 16-18, June 15-17, and July 18-20, 2018:
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.
Effects of Residential Development on the Water Quality of Higgins Lake:
The report below, prepared by Russel J. Minnerick of the US Geological Services (USGS), summarizes the results of a sampling program conducted over five years (1995-99) and describes the effects of residential development and associated land use on Higgins Lake water quality. This study provides a tool for community leaders in making decisions as to the best way to protect the water quality of Higgins Lake for future generations.
This report cites that lawn fertilizer run-off and particularly septic systems, due to their leaching effluent containing E. coli bacteria to the water table, are the most prevalent sources of increases in excess nutrients (phosphorus, nitrogen, etc.) in lake and ground water near shore, contributing to the accelerating degradation of water quality.
