Anyone who designs water, wastewater, transportation or land development projects on the Western Slope is working inside the Colorado River system, whether the drawings say so or not. That is why ACEC Colorado asked Amy Ostdiek, section chief at the Colorado Water Conservation Board, to open the featured presentations at the West Area Member Meeting in Glenwood Springs on Sept. 17.
Her topic was big river issues on the Colorado River, and she started where the story starts: the 1922 Colorado River Compact, the agreement that still frames how the river is shared more than a century later. From there she walked through the big river issues shaping the system today.
For engineers, the takeaway is that the river's condition sets the terms for supply planning, storage, conservation and the regulatory environment every project has to clear. Firms that understand where the hydrology and the interstate conversations are heading can advise clients earlier and design with fewer surprises. That is a competitive advantage, and it does not take a bigger staff to earn it.
The CWCB is one of the agencies ACEC Colorado meets with on a regular basis, alongside the State Engineer and the Mile High Flood District, so this conversation continues well beyond one afternoon in Glenwood Springs.
Thank you to Amy Ostdiek and the Colorado Water Conservation Board for a clear picture of a complicated river.
