Sadly, the occasions once I’m probably to get a peek on the Platte River are solely once I’m crossing over it on I-80, driving to or from the various conferences the place I sit in a room and discuss to individuals concerning the Platte River. However on my method house from a kind of conferences proper after Labor Day, I saved time to spend the night time on the shores of Lake McConaughy. It could appear unusual to rely this big reservoir as a part of the Platte River, however it’s really integral to this river system and the whole lot that’s helps downstream. And proper now, Nebraska’s largest reservoir is presently sitting solely 1 / 4 of the best way full, close to the record-low ranges measured in 2004. Actually there was an abundance of sandy seashore out there to pitch a tent – but additionally an eeriness when imagining the immense quantity of water that beforehand held that house.
Lake McConaughy was constructed within the Forties to retailer water when North Platte River flows had been working excessive within the spring and to make that water out there later within the yr, when summertime provides had been decrease than what farmers wanted for irrigation. At the moment, water saved within the reservoir serves many functions, together with irrigation, energy manufacturing, neighborhood water provides, recreation, and environmental wants. And the quantity of water out there within the reservoir is intently tied to what occurs a lot farther upstream. Snowpack that accumulates within the Rocky Mountains of Colorado and Wyoming over the winter is one in every of our greatest indicators of how a lot water will stream into Lake McConaughy and ultimately downstream alongside the Platte.
Deciding when and the way a lot water to launch from Lake McConaughy is due to this fact a giant job—and one which entails many companions. Historic agreements present pointers for a way the reservoir is to be operated, however balancing water wants throughout extended drought requires broad collaboration.
A small however important portion of the water saved in Lake McConaughy is devoted to an Environmental Account, which is used to assist threatened and endangered species and their habitat on the Central Platte. These releases assist maintain the Platte River ecosystem all year long, not simply throughout spring crane migration. Winter and early-season streamflows assist keep the river and its meals net, supporting the aquatic life, bugs, and vegetation that cranes depend upon. When greater than one million Sandhill Cranes arrive in spring, wholesome river flows additionally present open channels the place cranes can safely roost at night time, giving them an early-warning system for predators and serving to them preserve treasured vitality for migration. The advantages don’t cease with cranes as a latest financial evaluation exhibits that the spring Sandhill Crane migration helps a $28M ecotourism trade alongside the Central Platte.

However local weather change is including one other layer of complexity. Longer and extra extreme droughts are anticipated to turn into extra frequent, notably within the western Platte River Basin. As a result of water shortages have an effect on each individuals and ecosystems, we have to suppose forward about the right way to keep away from crossing over vital ecological and socioeconomic thresholds from which restoration turns into more and more tough.
That’s why Audubon and our VESPR companions (Imaginative and prescient for an Ecologically Sound Platte River) are planning a climate-focused state of affairs planning course of starting in late 2026 and persevering with into spring 2027. By bringing collectively individuals who perceive the wants of agriculture, energy manufacturing, communities, wildlife, and the river itself, we are able to discover a spread of doable futures and establish actions that assist construct resilience. Instruments like state of affairs planning – that unveil some readability within the clouds of uncertainty that we and our companions make selections beneath – are our greatest technique of forecasting the right way to steadiness future water wants for birds and other people.
