The dam was constructed in 1965 and has <br />served as a major flood control structure ever since that time. On <br />flood level measurements made by the Corps of Engineers and <br />previously submitted to the Division, the effect of the Paonia <br />Reservoir on flood stage levels near the Bear No. 3 operation were <br />not considered; therefore, with the proper use of regulating flow <br />from the Paonia Reservoir, the fnrn~ of Engineers can assure that <br />the flooding downstream will be minimi~Pd nr alimina P . <br />N``J,4 sO~'~4~~ ~ Furthermore, during the relocation of the river channel by the <br />~^' t~~u+~`v Colorado Division of Highways during the reconstruction work for <br />do~u'^ ~ey«~a r State Highway 133, special attention will be given by the Colorado <br />~Q~, ~ Division of Highways to reconstructing the channel so that flood <br />~l ~ Pra~c ~},~ potential is minimized or completely eliminated. <br />~_ f~"~ P Stipulation No. 3 <br />a' <br />As discussed on page 2.04-29 of the Bear Coal Company permit <br />application, no water has ever been produced from the workings of <br />the old Edwards Mine; and, therefore, no problems with water <br />discharging from the Bear No. 3 portals ar-e expected.
