Angler-Driven Citizen Science: Monitoring Black Bass Populations in Arkansas

In Arkansas, the rugged terrain of the Ozark and Ouachita Mountains dominates the north and west, eventually yielding to the vast, fertile flatlands of the Mississippi River Delta to the east. Hundreds of reservoirs and lakes punctuate the landscape, while swift streams snake through the valleys and hills, eventually giving way to the slow-moving rivers and bayous in the south. The waterways of the state are teeming with life. Black bass dominate most of these ecosystems and have drawn anglers for centuries. The most sought-after fish in one of the country's most prominent fishing states, Arkansas treasures its black bass populations.

New Buoy Boosts White Lake’s Water Quality Monitoring and Conservation

White Lake in Western Michigan is a vestige of North America’s glacial past, and gets its name from an interpretation of the Indian, “Wabish-Sippe,” meaning the river with white clay. The twin towns of Whitehall and Montague, which nestle on White Lake’s shore, have shared a close connection with the lake since their foundation–from the growth of the lumbering industry, to industrializsation, the expansion of tourism, and most recently, environmental protection. The White Lake Association (WLA) was founded in 1988 by residents concerned about proposed development at the lake’s northern end.

Flow Photo Explorer: Studying Flows in the Penobscot River Basin

The flow dynamics of rivers and streams play an essential role in the chemical and physical functions of aquatic ecosystems. In Maine, varying flows in the Penobscot River Basin have impacted the health of the ecosystem, water resource use, and habitat suitability for native species—topics of particular concern to the Penobscot Indian Nation , who have been protecting and managing the waterway for millennia. Parts of the Penobscot basin have been monitored by the USGS stream gage network, which covers larger streams and rivers but excludes many of the small streams found on tribal lands.
