El Dorado Irrigation District’s Jenkinson Lake at Sly Park is 93 percent full, General Manager Jim Abercrombie reported Feb. 25.
As of Feb. 19 it had 38,231 acre-feet of water. The maximum storage is 41,033 acre-feet and the maximum elevation is 3,466.58.
The historical month-end average is 84 percent, according to Abercrombie. However, EID has boosted Sly Park by diverting about 4,000 acre-feet through the Hazel Creek Tunnel from the El Dorado Canal, Abercrombie said. The canal is supplied by four alpine reservoirs, with releases from Caples Lake figuring most prominently in augmenting Sly Park’s water storage.
Caples Lake is at 67 percent of capacity with 14,903 acre-feet of storage as of Feb. 19. Its maximum storage is 22,338 and maximum elevation is 7,959.5. Inflow into Caples on Feb.19 was 6 cubic feet per second. The low inflow number is a consequence of the lake being frozen over and surrounding snow melting at a slow rate due to the coldness at that altitude. Outflow was 12 cfs.
