The park balances developed campgrounds and day-use facilities with protection of natural features, demonstrating how recreation and conservation can coexist through thoughtful planning and management.

Arrow Lake Provincial Park supports wildlife typical of Ontario's boreal transition zone. White-tailed deer are common, often observed along forest edges and roads, particularly in early morning and evening. Black bears pass through the park periodically, attracted to berry patches and natural food sources. Moose occasionally visit wetland areas and lake margins where aquatic vegetation provides forage. Beavers have established lodges and actively modify wetland habitats through dam building. Small mammals including red squirrels, chipmunks, snowshoe hares, and various mice and vole species inhabit the forests. The lake supports healthy fish populations including northern pike, walleye, lake trout, and various panfish species, attracting anglers and aquatic predators. Common loons nest on the lake and their haunting calls provide characteristic northern soundscapes. Other waterbirds include mergansers, great blue herons, and various duck species. Songbirds such as warblers, thrushes, and sparrows inhabit forested areas. Raptors including ospreys and bald eagles hunt over the lake. The park's mix of habitats supports diverse wildlife despite recreational development.

The park's vegetation reflects the boreal forest zone with Great Lakes-St. Lawrence influences. Coniferous forests dominated by jack pine, black spruce, and white spruce cover much of the park, adapted to the acidic, nutrient-poor soils of the Canadian Shield. White birch, trembling aspen, and balsam poplar provide deciduous components, creating fall color displays and early successional forests after disturbance. Eastern white pine and red pine occur on warmer, drier sites. Balsam fir grows in the understory and in mixed stands. Wetland areas feature black spruce, tamarack, and characteristic bog plants including Labrador tea, leatherleaf, and sphagnum mosses. The understory includes blueberries, bunchberry, wild sarsaparilla, and various ferns. Rocky outcrops support unique plant communities with lichens, mosses, and drought-tolerant species. Riparian zones along the lake feature alders, willows, and various wetland grasses. The forest shows evidence of past logging and fire, with stands in various successional stages. Spring brings wildflower blooms before canopy closure.

Arrow Lake Provincial Park sits on the Canadian Shield, featuring Precambrian bedrock among Earth's oldest geological formations, dating back over two billion years. The exposed bedrock consists primarily of granite and gneiss, visible along shorelines and in upland areas where soil cover is thin. The landscape was profoundly shaped by Pleistocene glaciation, with massive ice sheets scouring bedrock and creating the characteristic knob-and-basin topography. Arrow Lake occupies a depression carved by glacial processes, deepened by ice and filled with meltwater following deglaciation approximately 10,000 years ago. Glacial deposits including till and outwash sands cover portions of the landscape, providing parent material for soil development. Glacial erratics—boulders transported by ice and deposited across the landscape—are scattered throughout the park. Bedrock outcrops display glacial striations indicating ice movement direction. Soils are generally thin, acidic, and nutrient-poor, typical of Shield landscapes. Post-glacial processes including weathering, erosion, and vegetation succession continue to modify the landscape.

The park experiences a continental boreal climate with significant seasonal temperature variation. Winters are cold and snowy, with average temperatures from -12°C to -18°C and substantial snow accumulation that typically persists from November through April. Arrow Lake freezes completely in winter, with ice thickness sufficient for winter activities by mid-winter. Spring brings gradual warming, with ice-out typically occurring in late April or early May, marking the transition to the active camping season. Summers are mild to warm, with average temperatures between 18°C and 24°C, ideal for camping, swimming, and boating. Summer days can be warm and sunny, though cool nights are common. Thunderstorms occur periodically, particularly in July and August. Fall brings cooler temperatures, spectacular foliage displays, and decreasing visitation. The camping season typically operates from May through September. Annual precipitation totals approximately 800-900mm, fairly evenly distributed throughout the year. Blackflies and mosquitoes are abundant in May and June, diminishing as summer progresses.

The Arrow Lake region lies within the traditional territories of Indigenous peoples, particularly Ojibwe communities, who utilized these lands for hunting, fishing, trapping, and gathering for thousands of years. The lake provided productive fishing and served as part of transportation networks connecting larger waterway systems. Seasonal camps were established at favorable locations for accessing resources. Archaeological evidence in the broader region indicates continuous Indigenous presence following deglaciation. European contact came with fur traders in the 18th and 19th centuries, with trading posts established on larger lakes in the region. Logging operations harvested the area's forests in the late 19th and early 20th centuries, with evidence of past forestry visible in forest age structure. The construction of roads to serve logging and mining operations improved access to previously remote areas. As northern Ontario communities developed, demand grew for nearby recreation areas. Arrow Lake's clean waters and scenic setting led to its establishment as a provincial park, protecting the area while providing public access for outdoor recreation.
