Tipton Creek Culvert Replacement, NC_FY10 Project
-
In the summer of 2011 the culvert at the Davis Creek Road (FSR 420) crossing of Tipton Creek was
removed and replaced with a concrete arch, stream simulation crossing for the purpose of passing
aquatic organisms, where the existing culvert was known to be a barrier to aquatic passage due to
velocity and outlet drop. The crossing was sized using the 100-year flow calculation derived from the
USGS Regression Equation for the mountains of North Carolina. Additionally, the width of the crossing
was designed to accommodate a bankfull flow channel dimension plus a small area of floodplain. The
channel was reconstructed through the crossing using the dimension, pattern, and profile of the
reference reach upstream. The new channel was constructed using imported boulders and onsite alluvial
materials. Grass seed was sown, and trees and shrubs were planted, both potted and live-stakes. Over
the last year since construction, the site has experienced several small flood events. The site remains
stable, passable to all aquatic species, and looks more and more natural every year as planted and
natural vegetation establishes.

Assessing the Efficacy of Remediating Episodic Low pH (and High Aluminum) Concentrations in Headwater Brook Trout Streams with Clam Shell Additions_FY09 Project
-
This project demonstrated that clam shells could be utilized to increase pH and decrease detrimental inorganic aluminum concentrations. In Dead Stream, water chemistry has improved by approximately 1.0 pH unit, and total fish densities increased two-fold. In Canaan Brook water chemistry has improved by 1.0 pH unit and First Lake Stream improved by 0.7 pH unit, while fish densities have increased 2- and 6- times, respectively. Macroinvertebrate communities have improved somewhat, especially among mayflies and stoneflies, while amphipods and snails have appeared for the first time. However, even at treated sites, macroinvertebrate communities continue to have low diversity and may not achieve Class A water quality. Overall, by adding buffering capacity, there has been a boost to the bottom of the food chain which has contributed to improved fish abundance and diversity. In the fourth year, biological communities are still adapting to the new conditions.

Quantifying the effect of semi-natural riparian cover on stream temperatures: implications for salmonid habitat management
-
Previous studies examining the effects of riparian cover on stream temperatures have led to highly variable
findings. In an attempt to reduce these uncertainties, this study examines the relationship between stream temperature
variability and local climatic conditions over discrete 300-m sections of a watercourse. Seventeen stream sections were
chosen within the Slaney catchment on the basis of riparian cover and size. Continuous monitoring over a 2-year period from May 2010 found that riparian cover had a measurable cooling effect on water temperatures at small spatial scales. The magnitude of this effect was dependent on stream size and local climactic conditions.

Northeast Aquatic Connectivity - An Assessment of Dams on Northeastern Rivers
-
Throughout the Northeast, hundreds of dams have been removed and hundreds of culverts have been replaced or retrofitted over the last two decades in projects where ecological restoration was a goal. To many working in the field of aquatic resource management it is apparent that given likely future constraints on availability of funds and staffing, it will be critical to be more strategic about investments in connectivity restoration projects. One approach to strategic investment is to assess the likely ecological “return on investment” associated with connectivity restoration. In order to complete an assessment at the regional scale, the Northeast Association of Fish and Wildlife Agencies (NEAFWA) awarded the Nature Conservancy (TNC) a 2007 Regional Conservation Needs (RCN) Grant. This RCN
grant was designed to have TNC support state resource agencies in the Northeast U.S. (fish and wildlife, marine fisheries, dam safety, etc.) in efforts to strategically reconnect fragmented river, stream, coastal, reservoir, lake and estuarine habitat by removing or bypassing key barriers to fish passage. The primary ecological goal of mitigating fish passage barriers is to enhance populations of fish including anadromous fish, coldwater species, and other species of greatest conservation need (SGCN).

Modified Culvert Inventory and Assessment Protocol
-
This culvert inventory and assessment method is a modified version of the National Inventory and Assessment Procedure (NIAP; Clarkin et al 2003) developed to collect data needed to run coarse filter evaluations of fish passage (Coffman 2005).
