There are currently 44 augmentation/recharge projects along the "',., S i} 1 nyl < ',;. ,-- . <- 2.2 ~ugmentation/Recharge Sites South Platte River listed in Water Districts 1, 2, and 64 at the State Engineer's Office. Not all of these are decreed and some are no longer operated. Several are listed as "temporary exchange agreements." which must, be reviewed once a year by the State Engineer. Most of these recharge si t,es were constructed with augmentation of stream 'flow in the South Platte River as their major purpose. However, several sites which are many miles from the river, 'or in tri butary valleys are operated to replace groundwater that has been pumped from a nearby well, and not to augment streamflow. The following ts a discussion of the currently active or recently active sites in the South Platte River Basin. The recharge sites are grouped according to the organization which operates the site. 2.2.1 Central Colorado Water Conservancy District The Central Colorado Water Conservancy District (Central) has five augmentation/recharge projects. The five sites are: (lA) Evans 2 (Platte Valley Ditch), (lB) Farmers Independent, (lC) Boxelder Creek (Bootleg Reservoir), (10) Mill Iron Draw, (lE) Kiowa Creek (50%). These sites are located south and east of Greeley, within five miles of the South Platte River mainly in Water District #2 (Figure 1). In this area the water table ranges from 0 to 10 feet below the land surface. Because of the shallow depth to groundwater, water logging during recharge is a problem. The saturated thickness of the aquifer in this area is about 30-60 feet. , . 13 ---- --~--"--------'--- L _L_~0~_
