Wyoming Nutrient Strategy

In 2016, DEQ and the Wyoming Nutrient Work Group began developing the Wyoming Nutrient Strategy. The strategy consists of priority items and next steps to address nutrient pollution in Wyoming’s surface waters from the following four areas:

                Criteria Development

                Point Sources

                Nonpoint Sources

                Education and Outreach

From the broader strategy, DEQ identified a subset of priorities for 2017, 2018, and 2019. DEQ and the Wyoming Nutrient Work Group will update the strategy and annual priorities as work is completed and adjustments need to be made.

After receiving feedback from the Nutrient Work Group, in May 2017, the Boysen Reservoir watershed was selected as the priority for implementing proactive point and nonpoint source nutrient reductions. Boysen Reservoir was selected due to its importance for recreation, its use as a public water supply, and the risk posed to these uses by recurring cyanobacterial blooms in the reservoir. As a preliminary step in better understanding the sources of nutrients to the reservoir, DEQ has compiled the existing cyanobacteria data for the reservoir as well as the nutrient data available for the reservoir and watershed. DEQ is now working to develop initial goals and objectives for the Boysen Initiative, which aims to protect public health and improve recreational experiences in Boysen Reservoir by decreasing cyanobacterial blooms through a reduction in nutrient contributions to the reservoir. DEQ has also started to incorporate nutrient monitoring requirements into Wyoming Pollutant Discharge Elimination System (WYPDES) permits in the Boysen Reservoir watershed as permits are renewed. This information will be used to help determine contributions of nutrients from points and inform nutrient reduction efforts.
