There is a boat launch and a trail that runs past the lake following the abandoned Belleville and North Hastings Railway.

The river on either end is accessible for about 1 km before rocks and the dams prevent further boat travel.

In dry summer weather, the Moira river may cease to flow in or out of the lake in order to maintain a more consistent level.

The wastewater treatment center of the town of Madoc releases effluent into the lake twice per year, usually over two 28-45 day periods.

On August 15, 1866 Marcus Powell and an old miner named Snider, searching high and low on John Richardson's farm, the men made a discovery: they found a vein of gold!

Word of the discovery remained a secret for a short time but with the available gold running at 22 carats pure, the story was bound to get out.

For example, a paper from 1993 revealed that "The sediments of Moira Lake, Ontario, have accumulated large quantities of arsenic and toxic metals since the 1830s when mining began in its drainage basin.

[7] Phosphorus counts performed on the lake demonstrate that Moira Lake has high total phosphorus concentrations associated with algae growth,[8] caused by a number of factors including its shallow average depth, agricultural practices and industrial impacts.
