From Colorado Trout Unlimited:
We are pleased to announce that one of the rubicon gates is fully operational on the Oligarchy Ditch and the remaining two are partially installed on the Palmerton and Highland Ditches. The ditches should be fully operational by late Spring if all goes well. Maintaining consistent flows in the St. Vrain river is the first step in strengthening the health of the river and the fish and animal life that depend upon the St. Vrain.
More instream flow coverage here.
