The section requires states to identify water bodies that cannot meet water-quality standards without control of nonpoint sources. The states must then identify best management practices (BMPs) and measures for those impaired sources, along with an implementation plan. The EPA approves these plans, and if a state fails to develop a plan, the ...
The Conservancy is a major recipient of water from the San Juan–Chama Project, a series of tunnels and diversions that take water from the drainage basin of the San Juan River – a tributary of the Colorado River – to supplement water resources in the Rio Grande watershed. 24% of the 3,755,307,600 cubic feet (106,338,470 m 3) annual supply ...

Opacity of the Earth's atmosphere: the radio window spans larger wavelengths. The radio window is the region of the radio spectrum that penetrate the Earth's atmosphere . Typically, the lower limit of the radio window's range has a value of about 10 MHz (λ ≈ 30 m); the best upper limit achievable from optimal terrestrial observation sites is ...
