Once drilling is completed the pad size will be reduced to 2.64 acres. Any pits will be constructed on cuts and will not be allowed on fills. Cuts will range from 0-9.9 feet. Fills will range from 0-10.1 feet.

Dam Facilities, Reservoirs, and Hydropower

HT Ranch Stock Water Reservoir 2019-09-09
HT Ranch, Inc, heretofore referred to as proponent, has requested of the DNRC Eastern Land Office permission to construct a reservoir on state owned tract T5S-R60E-Sec 16. This proposed reservoir would provide a more reliable water source for livestock in this area and encourage better grazing distribution, aiding in long-term productivity of the land.

Fred Burr Reservoir Dam Spillway Wall Stabilization Project 2019-09-05
Type and Purpose of Action: Approximately 70 feet of the lower left spillway wall is continuing to tilt. Deformation was first noticed in 1996 at ½” and was measured in May 2019 at almost 4 inches. The specific cause of deformation is unknown but freeze/thaw jacking seems the most plausible. Weep holes were drilled in 2017 to increase drainage behind the wall, but the wall has continued tilting by 0.7 inches. DNRC State Projects is concerned that further deflection may compromise safe spillway operation during the 2020 spring runoff and would like to stabilize the wall in Fall 2019 by excavating behind the wall, pouring a new concrete heel, installing a gravel filter drain, and backfilling to existing grade.
