Estimating Irrigation prior to 1900 Sources: History of Irrigation Development in Idaho, Lewis, 1924 Pioneer Irrigation, Upper Snake River Valley, Carter, 1955 Irrigated Eden, Fiege 1999 Madison County Findings 1) Irrigation Started around 1879 2) Water Rights filed before actual diversions began 3) The ‘Panic of 93’ led to the end of irrigation expansion 4) Around 1900 sugar beet factories

Estimating Unregulated Flow-Monthly Monthly Estimation Procedure 1) Rank Years by Annual Flow (1928-1997) 2) Calculate Average Monthly Hydrograph per category 3) Calculate standard deviation per category 4) F m = (F a – F avga )/STD avga *STD avgm +F mavg ) OctNovDecJanFebMarAprMayJunJulAugSepAnnaul 1 214.5179.8165.6155.8143.1166.8291.7726.1609274.5194.3172.73293.9 2 235.3200.8179.6171.4152.1170.6328.4728961.5439.7258.6204.14030.1 3 235.9202.1189.2175.6163.3173.1309.4875.41084.5495.9273.1230.24407.7 4 216.2194.8179.6176157.2175.6366.71110.31140.8578.6323251.44870.2 5 220.1191.1182172.5156.9175387.81144.11332705.2333.8253.85254.3 6 244.3216.8212.6198.9174.1193.5445.91225.71511969.1423.3287.16102.3 7 269.1246.3236.8222.7190.7248.2481.21453.32021962.6453.1329.77114.7 Validate r² = 0.82 Calibrate r² = 0.80 Validate r² = 0.87

Modeling Monthly Recharge 1880-1900 SD-SRPM (System Dynamics Snake River Planning Model) Model Assumptions 1) No minimum flow requirements 2) No reservoir storage 3) No groundwater pumping 4) Linear increase in irrigation demand from 1880-1900 5) 75% of current demand

14
Modeling Monthly Recharge 1880-1900 SD-SRPM (System Dynamics Snake River Planning Model) Findings 1) Correctly identify historic shortages between 1900-1905 2) Irrigation induced ESPA discharge (≈ 5 kaf) below Milner 3) Irrigation impact constant below Milner
15
Some Thoughts How to validate 1) SD-SRPM allows estimation of monthly recharge 2) Should validation be at a monthly timestep? 3) Possible uses of a Systems Model for ESHCM & IDWR Estimate Recharge (historic-availability) Estimate Recharge (land-use changes)
