Fish Habitat of the Tay River Watershed: Existing Conditions and Opportunities for Enhancement Completed by
Priority Enhancement Projects:
T2 – Leggat and Eagle Lake Sub-watershed
Although the riparian vegetation surrounding Leggat Lake remains intact, a number of cottage lots require minimal rehabilitation. Cottage owners should be persuaded to replant natural riparian species (e.g. red-osier dogwood (Cornus stolonifera), shrubby willow (Salex sp.), meadowsweet (Spiraea alba), Virginia creeper (Parthenocissus vitacea)) and maintain the natural vegetation around the entire lake. Property owners should also remember not to conduct work in or around water during sensitive bass spawning periods which usually occurs during the month of June. Anglers should not fish for species such as northern pike or walleye near bass spawning locations until nest guarding has ceased.
Several lake trout spawning shoals have opportunities for rehabilitation. The most important known spawning area used by lake trout is a large submerged shoal located in the northeast portion of the lake south of Camp Oconto. This shoal lies in roughly 0.5-1m of water and is surrounded by relatively deep water (5-15m). This shoal is mainly composed of varying substrate from large boulders to small cobble. Enhancement work should be concentrated on improving existing spawning habitat within this shoal by placing well washed, rounded limestone cobble ranging in size from 5-30cm in diameter. This material should be added in specific locations as recommended by OMNR, and not on the entire shoal.
Four potential lake trout spawning shoals also exist on the lake (Figure 2.2.2). These shoals have been identified as potential spawning locations due to their substrate composition. Lake trout are not known to spawn at these locations. Enhancement work in these areas should focus on improving substrate composition and increasing the size of these potential shoals.
Rehabilitation of riparian vegetation is required on many cottage lots on the peninsula and the south shore. Shoreline vegetation such as red-osier dogwood (Cornus stolonifera), shrubby willow (Salex sp.), meadowsweet (Spiraea alba), and Virginia creeper (Parthenocissus vitacea) should be restored to protect and maintain the strict water quality parameters for this cold water lake and its fish community. Funding and assistance in replanting efforts can be obtained through CFWIP and MAPLE.
3. Eagle Lake- Nutrient Input Reduction
Many small and easy steps can be taken to reduce nutrient inputs to Eagle Lake. Property owners could conduct the following for example:
These small steps can improve or at least maintain the present water quality and sensitive lake trout habitat of Eagle Lake.
