Red Mountain Mining District Tour Guide tells The Watch about historical sights

Hike into history

Winter tour to visit former mining sites, ghost towns

By JUSTIN CRIADO, Associate Editor, The Watch

Don Paulson brings books to life.

No, he’s not a magician or some type of “Pagemaster” practitioner. Paulson — curator of the Ouray County Historical Museum — has authored several texts about the region’s mining and railroad history, which he uses as guides during several informational tours throughout the year.

“I don’t think people can really understand history by just reading a book. History really comes alive when you see the actual remnants of the historical places,” Paulson said.

The winter edition of Paulson’s guided adventure — an approximately four-mile hike of the Red Mountain Mining District — will be Feb. 10 from 9 a.m. to 2 p.m. The tour makes stops at Yankee Girl Mine and the ghost town of Guston.

UWP reports on 2017 Hydrodam Sediment Release Study

The Uncompahgre Watershed Partnership (UWP) has completed its first report for the Ouray Hydrodam Sediment Release Study, detailing the water quality impacts of the annual release into the Uncompahgre River. Due to the release’s increased flows and concentrations of heavy metals compared to pre-release flows in the river,the study compares metals concentrations to water quality standards for various beneficial uses of water. Additionally, the study can help determine if there are any substantial environmental or public health issues created by the release.

UWP conducted the initial Ouray Hydrodam sediment release study in March 2017, during an early snowmelt period where flows were substantially higher than typical for March. Observations from this study are specific to this year’s event and additional study should occur to improve certainty.

Here is a link to the full Study Report, published in November 2017. In summary, the March 2017 study found the following:

Change in metal concentrations during the release: Total metal concentrations increased during the release and returned to concentrations similar to the pre-release concentrations. Dissolved metal concentrations decreased for most metals during the release. Dissolved metal concentrations generally returned to pre-release concentrations following the sediment release. Both patterns are expected given the large volume of water and sediment released from the sluice gate during the sediment release.

Metal concentrations and aquatic life standards: All metal concentrations attained aquatic life standards during the release.

Metal concentrations and human-health standards during the sediment release: The EPA classifies arsenic as a Class A carcinogen (most dangerous classification). This classification results in a very low human-health standard (0.02 ug/L of total arsenic). An ambient concentration of less than 10 ug/L is considered acceptable for raw drinking water supplies. Arsenic concentrations measured during the sediment release below the dam and near Ouray exceeded the human-health and raw water supply criteria; concentrations at CR-24 near Ridgway exceeded the human-health criterion.

The arsenic concentrations measured at all three locations exceeded the human-health criterion before and after the sediment release. Arsenic concentrations measured in the Uncompahgre River near Ouray and Ridgway occasionally exceeded the human-health and raw water supply criteria during the 15-year period of record.

Although the hydrodam sediment releases influence arsenic concentrations, there may be other sources and controls within the watershed. Additional study may be warranted to better understand arsenic concentrations and sources within the Uncompahgre River Watershed.

Other metals did not exceed human-health criteria.

Follow-up study required for better understanding: UWP plans to coordinate with local stakeholders to design a follow-up study. We secured partial funding for a 2018 study from Ouray County and the Town of Ridgway, and are seeking additional funding to implement the study.

Ridgway Updated Proposed Ordinance on River District Development

As a public service to inform the public of pending local legislation impacting the future of the Uncompahgre River, UWP is providing this link to the Oct. 13, 2017 version of

“An Ordinance Of The Town Of Ridgway, Colorado Amending The Official Zoning Map to Provide For The Uncompahgre River Overlay District, Creating River Corridor Development Regulations, And Amending The Town’s Subdivision Regulations For Preliminary Plat And Required Improvements.”

The proposed municipal law was created to accomplish Goal 4 of Ridgway’s 2011 Land use Plan Update to “preserve, restore, and re-engage the Uncompahgre River to strengthen the riparian corridor as an asset to the community”. It will be discussed at a public meeting at the Ridgway Town Hall on Wed., Oct. 18. It may go to a vote on first reading by Ridgway Town Council in November, and a final vote on second reading with a public hearing in December.

TMDL 2017-18

The Uncompahgre Watershed Partnership is hosting meetings to bring together local stakeholders with the Colorado Department of Public Health and Environment to partner in a process of determining the level of pollutants in local water sources, to provide direction for future remediation projects. The first meeting is Thursday, Oct. 19 at 6 p.m. at the Ouray Community Center.

Information available on the EPA’s website describes the TMDL Process as follows:

A TMDL (Total Maximum Daily Load) is the calculation of the maximum amount of a pollutant allowed to enter a waterbody so that the waterbody will meet and continue to meet water quality standards for that particular pollutant. A TMDL determines a pollutant reduction target and allocates load reductions necessary to the source(s) of the pollutant.

The objective of a TMDL is to determine the loading capacity of the waterbody and to allocate that load among different pollutant sources so that the appropriate control actions can be taken and water quality standards achieved. The TMDL process is important for improving water quality because it serves as a link in the chain between water quality standards and implementation of control actions designed to attain those standards.

Local citizens sometimes know more about what is happening in their watersheds than state agencies, and this knowledge can be a valuable aspect of TMDL development. The public often contributes useful data and information about an impaired waterbody. The public can often offer insights about their community that may ensure the success of one pollutant reduction strategy over another. Citizen information and participation can improve the quality of TMDLs that are developed and can ultimately speed cleanup of impaired waters or secure protection of threatened waters. Public/stakeholder roles in the TMDL process can include:

  • Providing data and information to the states.
  • Reviewing and commenting on impaired water list.
  • Reviewing and commenting on draft TMDLs.
  • Assisting in the development of TMDLs.

UWP volunteers share watershed lessons at five community events

In May and June 2017, volunteers with the Uncompahgre Watershed Partnership attended five different events around the watershed where they shared lessons and games about water ecology with youth of all ages from elementary to high school. The volunteers spent a total of 20-plus hours participating in watershed education during those two months, and reached up to 1,000 students. Here are some photos of the fun activities.
