Seasonal streamflow extremes are key drivers of Brook Trout young-of-the-year abundance
-
Based on counts of Brook Trout (Salvelinus fontinalis) collected over 28 yr at 115 sites in Shenandoah National Park, we developed mixed-effects models to (1) assess how well extreme streamflow, as compared to mean flows and total precipitation, can explain young-of-the-year (YOY) abundance, (2) identify potential nonlinear relationships between seasonal environmental covariates and abundance using nonlinear generalized additive mixed models, and (3) explore likely impacts of expected future weather and streamflow conditions.

Elevated summer temperatures delay spawning reduce redd construction for resident brook trout (Salvelinus fontinalis)
-
Redd (nest) surveys for resident brook trout (Salvelinus fontinalis) were conducted annually in a mountain lake in northern New York for 11 years with multiple surveys conducted during the spawning season in eight of those years. Elevated temperatures in summer were correlated with a delay in spawning and a reduction in the total number of redds constructed. Increasing the summer mean of maximum daily air temperatures by 1 °C delayed spawning by approximately 1 week and
decreased the total number of redds constructed by nearly 65.

Copper Creek In-Stream Habitat Restoration Project
-
This project improved riparian zones, water quality, appropriate sediment flows and restoring physical habitat for multiple listed aquatic species in the Copper Creek watershed, within the Upper Tennessee River Basin. (Photo: The low water bridge that was removed and replaced with a new bridge that spans the river.)

Green River Enhancement within the Green River WMA, KY
-
The Green River and Green River Lake and provide aquatic habitat in the Green River Wildlife Management Area. The river is in declining condition due to severe erosion over almost four decades. Its restoration can allow it to support thriving populations of white bass, smallmouth bass, rock bass, flathead catfish, walleye, and muskellunge, and provide sport challenges to anglers.

Harpeth River Restoration
-
As part of a jointly funded project via the National Fish Passage Program, the totality of this project is removing a lowhead dam and restoring the immediate area to riffle/run habitat for the benefit of improved water quality and native fish habitat in the Harpeth River, TN.

Nashville crayfish Habitat Restoration on the Nashville Zoo Property
-
Mill Creek Watershed has been negatively affected by urbanization,resulting in increased sedimentation,reduced habitat quality, ultimately resulting in the Nashville crayfish being federally listed. This project will restore an unnamed tributary of Mill Creek by removing a barrier and restoring connectivity of the tributary.

Raccoon Creek Stream Restoration for Imperiled Aquatic Species in lower Etowah River Drainage
-
This project restored stream areas of Raccoon Creek for imperiled aquatic species in lower Etowah River drainage, Georgia. This project has resulted in several new partnerships, including a collaborative planning workshop for Paulding County held by SARP and the Southeast Watershed Forum.
