Bald Eagle Closure in Effect Until July 31, 2014
Returning bald eagles are actively tending to last year's nest within the Pinery Narrows area in CVNP. To protect the eagles from human disturbance, the area surrounding the nest tree will be closed until July 31, 2014. More »

Closure on Fishing Will Remain in Effect for Virginia Kendall Lake
Due to the government shutdown, we were unable to survey the fish community in VK Lake as scheduled. Our survey partners (ODNR) will not be able to get into the lake until early spring of 2014. Therefore, the closure on fishing will remain in effect. More »
The Cuyahoga River, made famous by its troubled history of industrial pollution and spontaneous fires, lies at the heart of the Cuyahoga Valley National Park.
Just one of over a dozen fires on the Cuyahoga River, the 1969 blaze was nothing new. Industrial rivers, much like the Cuyahoga, burned frequently, but it was the preceding events that made the 1969 fire vastly different from the others. Time magazine published an article about the burning of the Cuyahoga River that would prove to be a pivotal turning point in the fate of the heavily polluted waterway. The "Mistake by the Lake," as the city of Cleveland was called, became a poster child for the environmental movement. Something had to change. The burning of 1969, and subsequent popularity, sparked legislation for the Great Lakes Water Quality Agreement and the Clean Water Act of the early 1970s. The Cuyahoga River, among many others, was on track to cleaner days.
The Cuyahoga River RAP works to plan and promote restoration of beneficial uses, such as fishing and canoeing, of the lower Cuyahoga and near-shore Lake Erie through remediation of existing pollution problems and prevention of future ones. Beneficial use impairments were identified in the Stage One Remedial Action Plan. Stage Two, implementation and restoration of beneficial uses, is only partially completed. Extensive research and monitoring by numerous agencies have been funded to improve understanding of water quality impairments within the watershed.
Currently, impairments to the water quality of the Cuyahoga River are being addressed under the Total Maximum Daily Load (TMDL) program. A TMDL is a written, quantitative assessment of water quality problems in a water body and contributing sources of pollution. It specifies the amount a pollutant needs to be reduced to meet water quality standards, allocates pollutant load reductions, and provides the basis for taking actions needed to restore a water body. The TMDL for the Cuyahoga River is divided into three sections, the upper, middle, and lower Cuyahoga. The section of the river that flows through the Cuyahoga Valley National Park is considered part of the lower Cuyahoga.

The park hopes to gain a better understanding of the ability of indicator organisms to predict the presence of human pathogens and, consequently, risks to human health. This information will improve our understanding of waterborne pathogen occurrence and assist the NPS in making informed decisions about when the water quality in the Cuyahoga River will be safe for recreational use in the future.
Visitors should still be warned to use caution when contacting Cuyahoga River water. While water quality has steadily improved over the past 40 years, contaminant and bacteria levels can still be high, especially after periods of rain.
