Increasing Northern Hemisphere water deficit
-
A monthly water-balance model is used with CRUTS3.1 gridded monthly precip- itation and potential evapotranspiration (PET) data to examine changes in global water deficit (PET minus actual evapotranspiration) for the Northern Hemisphere (NH) for the years 1905 through 2009. Results show that NH deficit increased dramatically near the year 2000 during both the cool (October through March) and warm (April through September) seasons. The increase in water deficit near 2000 coincides with a substantial increase in NH temperature and PET. The most pronounced increases in deficit occurred for the latitudinal band from 0 to 40°N. These results indicate that global warming has increased the water deficit in the NH and that the increase since 2000 is unprecedented for the 1905 through 2009 period. Additionally, coincident with the increase in deficit near 2000, mean NH runoff also increased due to increases in P. We explain the apparent contradiction of concurrent increases in deficit and increases in runoff.

Kentucky partnership with Tennessee, Ohio and West Virginia will restore mussels in 180 miles of the Licking River
-
Imperiled species will benefit from a total of $5.6 million in grants for 16 projects in 12 states through the U.S. Fish and Wildlife Service’s competitive State Wildlife Grants program. The grants, which focus on large-scale conservation projects yielding measurable results, will be matched by more than $2.9 million in non-federal funds from states and their partners for projects that work to conserve and recover wildlife identified by states as Species of Greatest Conservation Need and their habitats.

Mapping our Rivers in High Definition
-
A project video produced by Tennessee Wildlife Resources Agency (TWRA) for Trutta Consulting LLC High Definition Stream Survey (HDSS) of the Caney Fork River below Center Hill Dam. The project was supported by the Cumberland Chapter of Trout Unlimited, Tennessee Department of Environment and Conservation and TWRA. We also worked with TWRA fisheries sampling crew to video and GPS their trout surveys that were completed at the same time as the HDSS project. This allows us to see the conditions that the fish were captured and determine what areas of the river are best for trout at different flow conditions.

N.C. Wildlife Resources Commission’s Whirling Disease Response Plan
-
On July 27, 2015, whirling disease was confirmed in rainbow trout collected from Watauga River in Watauga County– the first occurrence of the disease in North Carolina. Whirling disease affects fish in the trout and salmon family with rainbow and brook trout, two species found in North Carolina waters, being the most susceptible. The disease, caused by the microscopic parasite Myxobolus cerebralis, damages cartilage and skeletal tissue in trout, causing them to swim in a whirling motion.

Norwalk River Watershed Association
-
The Norwalk River Watershed Association, incorporated in 1996, is a nonprofit membership organization whose mission is to improve the water quality and fish and wildlife habitats of the 40,000-acre Norwalk River watershed; to restore the riverbanks, meadows and forests through invasive plant abatement and promotion of native species; to encourage recreational use of the river, the surrounding open space and its trails; and to promote research, legislative advocacy, education, cooperation, and action on the part of the stakeholders in the seven watershed towns in CT (Ridgefield, Redding, Wilton, New Canaan, Weston, and Norwalk) and NY (Lewisboro).

Ohio River Basin Fish Habitat Partnership
-
The Ohio River Basin Fish Habitat Partnership was formed to protect, restore, and enhance priority habitat for fish and mussels in the watersheds of the Ohio River Basin. We pursue this mission for the benefit of the public, but what brings us to the table is as diverse as the basin itself. Whether it is sport fish, mussels, imperiled fish, water quality, or one of many other drivers, what bonds us is the Basin and our desire to work together to protect, restore, and enhance her aquatic resources.

Partnering to Connect Citico Creek
-
Dam removal projects are best done in partnership and one of the best examples is the Upper Citico Creek dam removal project in Tennessee’s Cherokee National Forest highlighted in our short film Connecting Citico Creek. American Rivers teamed up with two federal agencies, the U.S. Fish and Wildlife and the U.S. Forest Service, to achieve the common goal of restoring aquatic habitat. Each partner brought their expertise and resources to the table to produce an efficient, high quality, low cost victory in the Little Tennessee River watershed.
