The services of preparation of the technical work project of kėdainiai city HTS on dotnuvėlė river are purchased. The hydromassage was built in 1972 at a distance of 1 km from the mouth of the Dotnuvėlė River. Dotnuvėlė River belongs to the Nevėžis river basin with an area of 1091.30 km2. The hydromassage consists of a poured dam of land and a culvert of excess water – the threshold of a practical profile without closures. Dam - an upper slope fixed by monolithic reinforced concrete slabs of a straight axle. Dam class – CC1; ridge altitude – 35,14 m; ridge width – 8 m; the width of the footpath is 3 m, the length of the ridge is 140 m. The upper slope in the zone of wave action is fixed with monolithic reinforced concrete slabs, higher by turfing, the lower slope is fixed – by pouring with black earth and sowing with perennial grasses. Slopes of the slopes: ma = 3.0, mž = 2.5. Type of culvert for excess water – threshold of practical profile, three openings, without closures; width of openings – 13 m; threshold height – 3 m; class – CC1; maximum calculated flow rate Qmax =75,5 m3/s, calculated probability 1 %. The pond can be emptied through the bottom water outlet. Pond water levels: normal dam level (NPL) – 32,20 m; the highest (fortified) level of the dam (FPL) – 33,12 m; minimum dam level (MinPL) – 32,02 m. Pond area at NPL – 9.1 ha; volume (at NPL) – 86.00 thousand tons; m3; Other parameters of the pond: length – 1.1 km; max. width – 0,30 km; avg. depth – 1,70 m; max. depth – 3,75 m.12.
