International Erosion Control Association (IECA)


Our Mission

The purpose of the Mountain States Chapter of the International Erosion Control Association is to provide a regional forum for the exchange and review of information related to the causes, effects, management, long-term impacts, and solutions for soil erosion, vegetation establishment and sediment control in the mountain states of Colorado, Montana, New Mexico, Utah, Wyoming, South Dakota and North Dakota. The active participation of government officials, academic leaders, researchers, manufacturers, consultants and contractors represents the diverse resources that will be available to members of the Mountain States Chapter.

Board Elections will be held in November 2023.

Gross Reservoir Expansion Project From a Stormwater Perspective

The goal of the Gross Reservoir Dam expansion is to raise the height of the dam by 131 feet and increase the reservoir capacity from 42,000 to 119,000 acre-feet. Learn about the stormwater control measures used including terracing, process water, closed wash systems, and stabilization techniques.

What’s New with Mile High Flood District Criteria for Stormwater Control Measures?

The Mile High Flood District is updating Chapter 4 of Volume 3 of the Urban Storm Drainage Criteria Manual. This presentation will provide an overview of the update process and will focus on updated criteria relevant to erosion control professionals related to the planning, design, construction, and maintenance of SCMs.

Featured Sessions
