(From Atlas of Oregon Lakes, Johnson et al. 1985) Magone Lake is a small natural lake in the Malheur National Forest of east-central Oregon. It lies at an elevation of 5000 feet above sea level in a small, forested drainage basin. The lake basin consists of a single elongate trough oriented north-south. A single intermittent stream, Lake Creek, enters from the north and the outflow is tributary to the East Fork of Beech Creek, which it joins about two miles downstream. The lake was named for Major John W. Magone, a nineteenth century resident of Canyon City who stocked the lake with fish. It is one of the few natural lakes in this part of the state and draws a large number of visitors each year. Most of them come for the fishing; lots of rainbow trout and brook trout are taken, and there reportedly are a few kokanee. The lake is open all year, and winter fishing through the ice is popular. A good Forest Service campground is located on the shore and boats can be launched easily. However, there is no fishing from motorboats, and a 10 mph speed limit on the water is enforced.
The concentrations of ions in Magone Lake are somewhat above average for Oregon lakes, except for the few lakes in areas of interior drainage. The concentrations of calcium and magnesium are particularly high, making the water relatively hard for surface water in Oregon. The lake becomes strongly stratified in summer, with a thermocline between 16 and 33 feet (5 and 10 meters). The deeper water is anoxic by late summer. Water transparency, total phosphorus and chlorophyl concentrations indicate that the lake is mesotrophic, although the strong depletion of oxygen in the hypolimnion would seem to indicate a more eutrophic lake. However, there are many submerged logs on the bottom and their decomposition may be responsible for the 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.
