(From Atlas of Oregon Lakes, Johnson et al. 1985). Dog Lake lies at an elevation of 5197 feet above sea level in the Goose Lake drainage basin. It was formerly called Dogleg Lake because of its shape, and the name has been contracted as a matter of convenience. It lies within the boundaries of the Fremont National Forest, but until recently most of the lakeshore was privately owned land. All land around the lake is now owned by the federal government, and it is a popular recreation site. Fishing is good for rainbow trout, largemouth bass, crappie, perch, and catfish. Two Forest Service campgrounds and a boat launch are available for visitor use. Dog Lake has been described by the Nature Conservancy as a rare example of a medium size, mid-montane, freshwater lake which is both accessible and in near natural condition. Excellent examples of both floating and rooted macrophytes are present, and the site is known for the waterfowl nesting habitat of the marshes lining the shore. Adjacent to the lake are herb-grass meadows which grade into the surrounding open Ponderosa pine-western juniper-low sagebrush forest.
The surface area of Dog Lake changes considerably during the year and from one year to another. At maximum extent it is nearly 500 acres. The data presented here indicate a surface area of 189 acres, mean depth of 13.5 feet, and maximum depth of 22 feet. This is deeper than other lakes in the area; hence the trophic state is lower than other lakes in the Goose/Summer Basin. Nevertheless, it is a naturally eutrophic lake, although at the lower end. The major ion concentrations, conductivity, and alkalinity are lower than average for the area, as are phosphorus and chlorophyl concentrations. Water transparency is good (9.2 feet; 2.8 meters); however, algal blooms of Microcystis and Anabaena frequently lower this transparency. The lake was not stratified on the date of sampling (7/6/82), but the bottom water was nevertheless devoid of oxygen. The lake bottom is largely peat and plant debris from the macrophyte beds, and this undoubtedly causes this dissolved oxygen depletion.
The list of plants below includes results of aquatic plant surveys conducted by the Center for Lakes and Reservoirs as well as aquatic invasive plant species detections that have been reported to iMap Invasives: an online, GIS-based invasive species reporting and querying tool.
Plants listed in the table below are categorized as native to Oregon, on the Oregon Department of Agriculture’s (ODA’s) Noxious Weed List, on the Federal Noxious Weed List, or non-native but not listed as noxious. Federal Noxious Weed List plants are plants determined by USDA to be serious threats to U.S. agriculture, irrigation, navigation, public health or the environment (7 C.F.R. 360.200). The ODA Noxious Weed categories are:
ODA Class A - weeds either unknown or with small enough infestations to make eradication or containment possible; targeted for eradication or intensive control.
ODA Class B - regionally abundant weeds (may have limited distribution in some counties); targeted for local/regional control on case-by-case basis.
