Mountain Lakes Wilderness Air Quality Report Wilderness ID: 071 Wilderness Name: Mountain Lakes Wilderness Mountain Lakes Wilderness Air Quality Report National Forest: Winema National Forest State: OR Counties: Klamath General Location: Southern Oregon Cascade Range Acres: 23,071 Thursday, May 17, 2012 Page 1 of 4 Mountain Lakes Wilderness Air Quality Report Wilderness ID: 071 Wilderness Name: Mountain Lakes Wilderness Wilderness Categories Information Specific to this Wilderness Year Established 1964 Establishment Notes The Wilderness Act of September 3,1964 Designation Clean Air Act Class 1 Administrative Fremont -Winema National Forest Unique Landscape Features Before its eruption and subsequent transformation into a large caldera (a broad, craterlike basin formed by volcanic violence), the area we call Mountain Lakes Wilderness was a 12,000-foot mountain, one of the giants of the southern Cascades. Glaciation then carved up the caldera, leaving a scattering of small alpine lakes instead of one enormous body of water, such as Crater Lake National Park to the north. Only eight prominent peaks remain of the caldera's rim. Unique to the National Wilderness Preservation System, this area is the only Wilderness with a perfectly square boundary. Long appreciated for its wonder, Mountain Lakes was one of the three original Primitive areas created in 1930 in the Washington- Oregon region. Mosquitoes fly thickly from snowmelt to mid-August, snack food for the rainbow and brook trout in the lakes.

Fauna Actions: Collect and analyze fish for mercury concentrations from the most frequently fished lakes. While on site, also collect water samples from these same water bodies and analyze for anions, cations, and nutrients. Flora Flora Priority: High Flora Receptor: Lichens Flora Indicator: Changes in community composition Flora Trends: Not reported in the database. Flora Priority 2: High Flora Receptor 2: Lichens Flora Indicator 2: Concentrations of N, S, P, Cd, Cr, Pb, Hg, Ni, Ti, V and Zn Flora Trends 2: Not reported in the database. Flora Priority 3: Low Flora Receptor 3: Ozone Flora Indicator 3: Visible injury on ozone-sensitive plants Flora Trends 3: Not reported in the database. Flora Actions: Waiting for lichens to be scored for both baseline and trends for changes in community composition. Repeat visits to lichen plots once every 10 years. While on-site, consider surveying sensitive vegetation for ozone injury. Visibility Visibility Priority: High Visibility Receptor: Scenic Views Visibility Indicator: Regional haze Visibility Trends: Decrease Visibility Actions The IMPROVE visibility monitor at Crater Lake National Park (CRLA1) is representative of Mtn Lakes Wilderness. See the Oregon Regional Haze Plan and IMPROVE monitoring reports for more information.

Analyze for anions, cations, and nutrients. While at the lakes, consider sampling fish for mercury. Challenge Points Fauna Challenge Points: Not reported in the database.
