About this map

Heeney serves as the primary gateway to a high-elevation watershed defined by complex water management and massive topographical relief. The northern reaches are dominated by the Green Mountain Reservoir and the drainage of Elliott Creek, while the Noonan Ditch reveals historical efforts to divert water through this alpine environment. As the elevation climbs toward the southern peaks, the landscape becomes a dense network of high-country basins containing Lower Cataract Lake, Tipperary Lake, and Mirror Lake.

The southern boundary of the map is anchored by the imposing height of Mount Powell and Eagles Nest, part of a jagged ridgeline that separates these drainages. Human infrastructure is concentrated around the northern valley roads and the containment of mountain runoff, visible at Hoagland Reservoir Number 1 and its associated Hoagland Number 1 Dam. This region demonstrates the vital role of mountain snowmelt collection, with numerous creeks like Otter Creek and Black Creek feeding into downstream reservoirs.
