3. REcoRDS OF STREAM FLow. 
(a) The Investigation of Rivers, Final Report, by A. Strahan, N.F. Mackenzie, 
H. R. Mill, and J. S. Owens (published by the Royal Geographical 
Society, 1916). 
This report and the four interim reports, published from 1908 to 1911, deal 
with the discharges of the rivers Severn, Exe, Culm, Creedy and Medway, 
and contain a report on the rainfall of the Exe Valley. 
(b) Monthly Reports of the Thames Conservancy. 
These give daily values of the natural flow and rainfall over the Thames 
Valley above Teddington Weir. The Annual Reports of the Metropolitan 
Water Board, published since 1903, give monthly totals as above. 
(c) ‘ Gauging and Recording the Flow of Streams,’ by S. C. Chapman. 
Trans. Inst. Water Eng., vol. xv, 1910, p. 147. 
(d) ‘The Yield of Various Catchment Areas in Scotland,’ by W. C. Reid. 
Proc. Inst. Civil Eng., 1913. Paper No. 4048. 
(e) ‘ The Measurement of the Flow of the River Derwent, Derbyshire,’ by 
E. Sandeman. Proc. Inst. Civil Eng., 1913. Paper No. 4056. 
(f) ‘ Investigations into the Flow of the River Dee,’ by C. H. Roberts. 
Trans. Inst. Water Eng., vol. xxiv, 1919, p. 60. 
(g) ‘ Notes upon the Average Volume of Flow from Large Catchment Areas 
in Ireland ; the probable duration of stated rates of flow, etc., deduced 
from gaugings on the River Shannon at Killalow,’ byJ. Chaloner Smith. 
Proc. Inst. Civil Eng., Ireland, January 1919. 
(h) Annual Reports of the West Riding of Yorkshire Rivers Board. 
Some data relating to the flow of rivers have been given in these reports, 
e.g. in that on the river Don, issued in 1923 (Special Report No. 755): 
(i) Quarterly Reports of River Flow Records, Ness Basin, Rivers Garry and 
Moriston, 1929-31, by W. N. McClean. 
Continuous records of water level are kept at seven or eight principal 
points on the Ness Basin of 700 square miles, and the flows of the rivers 
Garry, Moriston and Ness have been measured for all water levels between 
ordinary low water and ordinary flood level. The reports give daily 
comparison of rainfall, water level and flow. The records are being main- 
tained and are prepared for publication when the opportunity occurs. 
A paper on this subject by W. N. McClean was published in the 
Geographical Fournal, vol. lxxvi, 1930, No. 1, pp. 39-49. 
(j) ‘ The Lochaber Water-Power Scheme,’ by W. T. Halcrow. Proc. Inst. 
Civil Eng., 1931. Paper No. 4796. 
4. LAKES AND RESERVOIRS. 
(a) ‘ Bathymetrical Survey of the Fresh-Water Lochs of Scotland,’ by 
Sir John Murray. Geographical Journal, vols. iv, ix, xv-xviii, xxii- 
XXVili, Xxx, xxxi, and xxxvi. 
(b) ‘ The English Lakes, with Bathymetrical Maps and Illustrations,’ by 
H.R. Mill. Geographical Fournal, July and August 1895. 
(c) Some statistics as to storage capacities of the various water undertakings 
are given in the Section on Waterworks Statistics in the Water 
Engineers’ Handbook and Directory, 1932, and in the Return as to 
Water Undertakings in England and Wales, published by the Local 
Government Board, 1914 (see 1, a).
