About ACLA

Mission and values

ACLA is a not-for-profit "umbrella" organization representing the lakefront areas between Amberley and Goderich in Ashfield-Colborne-Wawanosh Township, Huron County, Ontario. ACLA's mission is to coordinate advocacy on common concerns of the lakefront community. The values that membership in ACLA provides to the lakefront community are:


ACLA's programs are funded by annual contributions from the participating lakefront associations.

Representation and communication

Representation in ACLA is voluntary. Each participating lakefront association provides a "Communications Coordinator" and a designated backup, and the Steering Committee provides overall coordination.

ACLA Communication Coordinator meetings are held in May each year on the Saturday before the Victoria Day weekend. Invited presentations usually include ACW, MVCA, Huron Perth Public Health, and others.

Lakeshore concerns

Here is a list of the by-laws and regulations that are relevant to lakefront property owners.

Property Development and Protection

Most of ACW's lakefront seasonal properties are subject to Ontario's regulations for development within the 100-year erosion line of the Lake Huron shore and bluff. For details, see MVCA shoreline and gully maps and regulations.

The Lake Huron Centre for Coastal Conservation offers a number of community programs and has many guides that are of particular interest to lakefront property owners.


Pollution that affects the lakeshore community is an on-going concern. DNA analysis of tests done by ACLA in 2003 showed that the E.coli source is animal, not human. The results of ACLA's annual stream-testing program since then show that the dominant cause is untreated run-off from agricultural activities. This was clarified in a UoGuelph/MOE DNA-analysis research report published in 2009, conducted in 2005/2006 around 18 Mile River, which confirmed that the sources of E.Coli were 59-62% livestock/manure run-off, 16-18% persistent swash-zone E.Coli, 5-14% wildlife, 2-3% human, and 8-16% unquantifiable mixed sources.

Through its lakeshore environmental strategy, ACLA works to reduce the effects of agricultural runoff. These efforts led to the creation of the Healthy Lake Huron program to promote safe and clean beaches from Sarnia to Tobermory. Five key watersheds were identified as priorities for immediate action. Program staff work with local partners to develop and support the implementation of watershed management plans, with specific targeted actions, as well as monitoring and research needs, for each priority area. The priority in our area is the Garvey-Glenn Project. For more information, see the HLH reports.

Source Water Protection

Ontario's Clean Water Act is intended to keep contaminants from seeping into the sources of our drinking-water lakes, rivers, and aquifers. The Ausable Bayfield Maitland Valley Drinking Water Source Protection Committee is responsible for developing proposed policies for our area. Huron County also has a number of related water-protection programs.

Inspection of septic systems

ACLA has been urging this since 2002. In 2005, the Huron County Health Unit initiated a voluntary re-inspection program, and inspected 174 properties in 2005 and 178 in 2006. In 2010, HCHU proposed a mandatory inspection program, but the program failed to get support from enough of the nine municipalities. With the 2020 merger of the Huron and Perth health units to form Huron Perth Public Health, responsibility for approval of septic systems shifted to ACW under the Chief Building Official.

At the beach

Each year, June through August, HPPH measures the E.coli levels at all public and some test-case beaches. Levels change from day to day. E.coli levels are closely related to whether rainfall has recently carried pollutants from inland via the streams, and whether the water has recently been churned by wave action. If you are in the lake up to your waist and cannot see your feet, it is not advisable to be in the lake that day.

HCHU beach results

The HPPH website contains recent reports. For 2000-2007, we thank the former HCHU for providing the data from which we compiled the summaries for 2008-2012, 2007, 2006, 2005, 2004, 2003, 2002, 2001, 2000, and this trend-line graph.

In the streams

In conjunction with MVCA, ACLA conducted water-quality tests for a number of years to help identify the inland sources of contamination (see location map) ... 2014 2013, 2012, 2011, 2010, 2009, 2008, 2007, 2006, 2005, 2004, 2003, 2002, 2001.
