Work to reconstruct the Argo Dam headrace on the Huron River in Ann Arbor is moving along quickly. Livonia-based TSP Environmental, the firm hired last year to complete the $1.17 million project, has been hard at work since August. In a few short months, its crews have transformed the headrace — a 1,500-foot channel that canoeists and kayakers use to bypass Argo Dam — into a new series of drop pools surrounded by rocky formations. Other new features coming with the project include a wider and smoother Border-to-Border trail section and a 30-foot bridge along that trail that was installed this week. Read the story.
