RETALLACK Department of Earth Sciences, University of Oregon, Eugene, OR 97403, USA. *Email: gregr@uoregon. edu (Received 09 September, 2019; revised version accepted 15 December, 2019) ABSTRACT The Palaeobotanist 68(1–2): Retallack GJ 2019. Ordovician land plants and fungi from Douglas Dam, Tennessee. The Palaeobotanist 68(1–2): xxx–xxx. 1–33. Ordovician land plants have long been suspected from indirect evidence of fossil spores, plant fragments, carbon isotopic studies, and paleosols, but now can be visualized from plant compressions in a Middle Ordovician (Darriwilian or 460 Ma) sinkhole at Douglas Dam, Tennessee, U. S. A. Five bryophyte clades and two fungal clades are represented: hornwort (Casterlorum crispum, new form genus and species), liverwort (Cestites mirabilis Caster & Brooks), balloonwort (Janegraya sibylla, new form genus and species), peat moss (Dollyphyton boucotii, new form genus and species), harsh moss (Edwardsiphyton ovatum, new form genus and species), endomycorrhiza (Palaeoglomus strotheri, new species) and lichen (Prototaxites honeggeri, new species). The Douglas Dam Lagerstätte is a benchmark assemblage of early plants and fungi on land. Ordovician plant diversity now supports the idea that life on land had increased terrestrial weathering to induce the Great Ordovician Biodiversification Event in the sea and latest Ordovician (Hirnantian) -

Aerating Weirs for Management of Reservoir Releases Gary E. Hauser TVA Engineering Services, P. O. Drawer E, Norris, TN 37828 W
Aerating Weirs For Management of Reservoir Releases Gary E. Hauser TVA Engineering Services, P. O. Drawer E, Norris, TN 37828 W. Gary Brock TVA Water Management, 400 West Summit Hill Drive, Knoxville, TN 37902 Introduction Two of the most significant environmental impacts of hydropower dams on downstream tailwater reaches in the Tennessee River Valley are 1) low dissolved oxygen (DO) concentrations during hydroelectric generation; and 2) lack of suitable minimum flow between generating periods. High-performance weirs are one of several technologies now considered at hydropower dams as part of TVA's Lake Improvement Plan, which is implementing various DO and minimum flow technologies at 16 dams by 1996. TVA has been developing, testing, designing, and constructing innovative aerating weirs to meet release improvement objectives since 1990. Aerating weirs are attractive compared to in-reservoir and in-hydroplant aeration methods because they are passive, reliable, require little maintenance, avoid turbine damage, and are capable of meeting both DO and minimum flow objectives with a single technology. This presentation updates water resource professionals on developmental features, advantages- disadvantages, and the performance results of these weirs. Two aerating weirs have been constructed below TVA hydropower dams. A labyrinth weir below South Holston Dam (Figure 1) on the South Fork Holston River was completed in December 1991. An infuser weir below Chatuge Dam (Figure 2) on the Hiwassee River was completed in November 1992. Although these weirs are quite different in design, aeration and minimum flow principles are similar. Reaeration of oxygen-deficient turbine releases is achieved by water overtopping the weirs and plunging into a downstream pool during generation in a process similar to natural waterfalls. -

All bait dealers must purchase a type 118 (resident) or 116 (nonresident) license annually and make all necessary reports as required to the Tennessee Wildlife Resources Agency. Only commercial fishers and bait dealers may harvest bait for sale. The harvest and use of bait by commercial fishers shall be regulated in the commercial fishing proclamation. 3. Under no circumstance shall live bait be intentionally released into Tennessee waters unless released into the waters from which the bait were harvested. 4. A licensed sport angler (with all required licenses and permits) can harvest game fish (including rainbow trout and sunfish) for use as bait from the wild using legal sport fishing methods. -
