RBC | Thank you to all the interested public and stakeholders for your commitment to finding the drivers of the algae in the White River. We also want to thank you all for your patience with our Technical Committee (TC) as they have put a great amount of time, effort, and energy into identifying the most critical elements to the Scope of Work (SOW) that will help identify the causes of the algae. This is a very complex problem that has evolved over time and it will require some time to identify the cause. It is anticipated that there is no one single cause or source of this problem. There are multiple rivers across the western United States that are experiencing the excess algae issue, much like the White River.
A quick review of what the Technical Committee has done reminds us that USGS had originally recommended we do a one-year study primarily up-river from Meeker. The TC asked USGS to provide a proposal that would also include studying the river all the way down to Rangely and to make it a multi-year study over concerns that one year’s worth of data would not be statistically significant. USGS came back to the group with that proposal which gave many of the committee members “sticker shock.”
Realizing that it would be a huge challenge to get down to the detail necessary, a five-member workgroup was appointed in January to work out those details and bring a recommendation back to the TC. The final recommendation from the workgroup is the culmination of many hours (days), conversations, meetings, emails, etc. I’m confident that the workgroup has done exactly what the TC asked.
In reviewing the USGS draft SOW, the workgroup literally dissected it into a chart where they evaluated it line by line based on prioritized questions. Then they developed and analyzed a more elaborate spreadsheet for more discussion so that they could sort based on priorities and the “core” tasks required to ensure scientific analysis and credibility to the study. There were a number of tasks that each individual would like to include but the group finalized the SOW based on the highest priorities ensuring scientific integrity in determining the cause of excess algae. The workgroup’s final step in the two-month processes is to present the final SOW to the technical committee on March 21.
The workgroup recognizes that there is a sense of urgency in finding the cause of the algae and has balanced that sense of urgency with a solid scientific-based study that will give us the best of both worlds. To identify different sources of nutrients in the White River as quickly as possible, the proposed SOW will analyze isotopic-signatures of oxygen and nitrogen from nitrate in various source materials and in the river during 2018. Please remember, there is no guarantee that the “signatures” will be different enough to help determine the potential source. While analyzing samples for isotopic signatures, the proposed SOW will simultaneously include efforts to help develop a better understanding of the physical and chemical properties controlling the algal growth.
The draft proposal includes annual progress reports from USGS to evaluate the next year’s proposed work based on findings of the current year. We will be using adaptive project management based on annual findings.
While the anticipated cost is more than any of us would like to see, the workgroup has done a great deal of individual research and determined that we do need all the components of this SOW. Discussion was had about the USGS preliminary costs being a little higher than potentially other researchers. The consensus of the workgroup was that with USGS providing 35 percent of the funding and their reputation of being nonbiased, they are the best entity to have do this research and analysis.
So, how are we going to pay for the study? We currently have commitments for a total of $60,000 for 2018. That leaves us approximately $30,000 to raise for 2018 work. The conservation district and others will be meeting with individuals and agencies during the remainder of March to solicit this $30,000 because it is too short of a time frame to get grant funding and it seems like it is a “doable” amount to raise for such an important issue to the community.
In ensuing years, we will be seeking support again from the stakeholders and applying for grants through the Basin Roundtable, the Colorado Water Conservation Board and others to be determined.
The White River Conservation District anticipates that we will have annual agreements with USGS for the study dependent upon funding availability and on adaptive research based on each year’s outcome.
The technical committee meeting will be March 21 at the Fairfield Center beginning at 11 a.m. At that time the workgroup will give a brief overview of their recommendations followed by a more detailed presentation of the SOW by USGS. We will break for lunch and reconvene at 1:30 p.m. for further discussion and public comment specifically on the proposal in anticipation of finalizing the SOW by end of the day.
Landowners and interested parties are welcome to attend the technical committee meeting and will have an opportunity to provide comment and input on the proposal during the public comment period. We strongly encourage that anyone interested in providing comment in the afternoon attend the morning session, where they receive a copy of the proposal and hear the presentations.
