Trust Us; It’s a Lake – Monitoring Groundwater at Lake McLarty

The drilling crew installing one of the groundwater monitoring bores at Lake McLarty in April 2021

An important part of the “Saving Lake McLarty” project, funded by the State NRM Program, was the installation of groundwater monitoring bores. The bores will allow us to measure the level of groundwater in and around the lake as well as water quality parameters such as salinity, pH and other indicators of activation of acid sulfate soils underlying the lake bed.

In April PHCC contracted a drilling crew install a series of groundwater monitoring bores in and around Lake McLarty. Back then the lakebed was dry and the crew found it hard to believe that they were standing in the middle of what would become a lake once the rains began.

After the installation of the bores we implemented monthly monitoring of groundwater levels to gather data on what’s happening underground throughout the year. As can be seen in the photograph, taking measurements in July necessitated the wearing of waders to get to the bores. The peak depth of the lake is usually less than 1 metre but with all the rain we’ve had this winter perhaps we’ll need a canoe next time!

Lake McLarty is a significant wetland within the Ramsar listed Peel-Yalgorup System (Ramsar Site 482), supporting large numbers of migratory shorebirds over spring and summer. In fact, the lake supports so many birds that in most years Lake McLarty meets some the criteria required to be considered a wetland of international importance in it’s own right. Collecting this information about the groundwater is vital to understanding the contribution of groundwater to the lake water levels; assessing the risk of acidity from acid sulfate soils underlying the lake and developing management strategies to maintain this vital habitat for waterbirds in the face of the threat of a drying climate.

Stay tuned for more details from our monitoring program, and also of the upcoming Friends of Lake McLarty Open Day on Saturday 16 October where you will have the opportunity to explore the lake first hand with expert guides, enjoy free coffee and food, children’s activities and free native seedlings for eligible residents.

This work is being delivered by PHCC through it’s “Saving Lake McLarty Phase 1: Addressing acidification, hydrology and habitats” project funded by the WA State NRM Program.

K4	IDENTIFY AND CAPITALISE ON MARKET OPPORTUNITIES
The Peel-Harvey has competitive advantages that should enable market opportunities to be capitalized on, including its close proximity to an international airport, emerging support facilities, comparatively affordable land as metropolitan areas become more urbanized, and its natural capital including a very productive area of the Wheatbelt. Capitalising on these opportunities will assist in employment and the social issues being experienced as a result of high unemployment.

B5	WATER RESOURCES ARE MANAGED AND USED WISELY
Water resources are essential to life. They shape our wetlands, waterways and biodiversity and influence the type and location of agricultural production. Water resources include both surface waters and groundwater, and the aquifer systems that link them both. Most of the forested areas of the Forest and Scarp Subsystem are proclaimed water supply catchments (Land Assessment, 2005). Water resources are managed under a regime which recognises both public and private use values as well as environmental water requirements. The strategies to achieve this goal support water allocation planning and other activities to ensure the wise use of resources for protection of ecosystems in the long term. These strategies complement the Department of Water’s role in water allocation planning.

B5.2.2	Support resource users to implement water efficiencies
B5.2.3	Support adaptive management systems to respond to reduced rainfall

B4	BIODIVERSITY IS CONSERVED
Biodiversity is the term used to describe the natural diversity of life. This diversity exists at the ecosystem, species and genetic levels. The Region is recognised as a global biodiversity hotspot because of its mega-diverse and unique biodiversity and the level of threat this biodiversity is under. Biodiversity is most effectively and efficiently conserved by protecting natural areas, these being areas of bushland, forest, woodland, waterway, wetland, dune, rock outcrop, foreshore and any other area in a near-nature state. The Region is home to many globally significant natural areas, notable examples being Dryandra Woodland, our Northern Jarrah forest, and the Peel-Yalgorup Ramsar System. The strategies to achieve this goal are focused on protecting priority natural areas, managing and reducing threats to biodiversity assets, and restoring ecological linkages between significant natural areas. Assisting local governments to implement local biodiversity strategies will be one of a number of ways of achieving this goal.

B4.2.3	Implement and support management and response planning for extreme natural events
B4.3	Restore ecological linkages
B4.3.1	Facilitate and/or support collaborative landscape scale restoration for multiple benefits
B4.3.2	Encourage restoration processes being identified and embedded into the land-use planning system

B3	COASTAL AND NEARSHORE AREAS AND PROCESSES ARE RESILIENT AND VALUED
Coastal foreshores, beaches and near-shore areas have significant social, ecological and economic values. They support commercial and recreational fisheries, protect coastal residential areas and provide a diversity of habitat for flora and fauna. A key aspect of coastal management in the Region is the network of community groups, local governments and state agencies that manage coastal foreshores and maintain public access to beaches and nearshore waterways. Strategies to achieve this goal are aimed at supporting the groups and organisations who are undertaking coastal area and near-shore management.
B3.1	Protect foreshores for their ecological and recreational values
B3.1.1	Encourage/support foreshore management that enables natural process and resilience to a changing climate
B3.1.2	Support the community to value and manage coastal areas
B3.1.3	Support recreational uses consistent with environmental protection
B3.2	Protect near-shore habitats for productivity and biodiversity
B3.2.1	Support actions/activities to protect near-shore habitats for ecological, recreational and commercial productivity

B2	SOILS ARE HEALTHY AND PRODUCTIVE
Soils and landforms are the fundamental resources which shape wetlands and waterways, biodiversity and land use, especially agriculture. Agricultural production in the Catchment is worth $469.974 million per annum (source 2021 REMPLAN) and relies directly on the health and conservation of soil resources. Soils should be managed as a living resource with consideration to soil acidity, dryland salinity, prevention of erosion and discharge of sediment. Biosecurity is an issue of significant concern to the community and is included under this goal given its impact on soils, productivity and biodiversity. Issues such as water repellence and compaction of soils may also be having an impact on farm productivity levels, although the impact on productivity is not clearly understood. Healthy soils will reduce the loss of topsoil to waterways and the impact of sediment on rivers and the Estuary. Strategies under this goal aim to assist farmers and land managers to better understand their local soils, make informed decisions on soil management practices, and support biosecurity programs. Farmers own and manage over 50% of the Region, making their increased participation in NRM essential.

B1	WETLANDS AND WATERWAYS ARE HEALTHY AND PRODUCTIVE
Wetlands and waterways have a special place, with all major townsites and communities living in proximity to a local waterway or wetland. Major waterway assets include the Hotham, Williams, Murray, Serpentine, North and South Dandalup and Harvey rivers. Major wetland assets include the Peel-Harvey Estuarine System and the Peel-Yalgorup Ramsar System. Key threats include poorly planned development, changing hydroperiods, reduced flow, eutrophication, ASS and MBO. Strategies to achieve this goal are designed to support coordinated management of the Estuary and Ramsar System, implement management actions to improve waterway and wetland condition, and protect groundwater quality and flows into wetlands and waterways.
