In a survey conducted during January 1981 (Dwight and Trihey 1981), agencies and special interest groups asked the following questions: 1.what permitted or licensed water use rights presently exist in the Susitna River basin; 2.would operation of the dam allow present day out-of-stream diversions to be maintained;and 3.would postproj ect flows result in.a change of water table conditions that would adversely affect domestic wells or surface water supplies. This report provides an interpretive summary of existing water rights in the Susitna River basin to enable Acres American Inc.(Acres)to prepare the required information for the application for license and to assist in identifying any ~dverse effects that the proposed project might have on existing water rights claims. -3- WATER RIGHTS DATA Water rights are administered by the Alaska Department of Natural Resources (DNR). The legal documents protecting water rights are certificates,permits,and applications.Certificates are issued for water rights that have been perfected,i.e.,the water is being bene- ficially used.Permits are issued for water rights that are waiting final approval following the construction of structures necessary to use the water.When DNR accepts an application to develop water rights,the priority date of appropriation is established.However,approval pends on the development and perfection of the water right as well as adjudi- cation of the quantity requested to protect prior appropriations. DNR's Water Management Section has computerized certain data from the water rights case files on all certificates,.permits,and applications pending.Computer files are updated monthly.The computer files contain the following information: 1.water rights identification number and standard industrial code classification number for each type of water use associ- ated with that water right; 2.the quantity of water appropriated and diverted,expressed as c~bic feet per second (cfs),gallons per day (gpd),acre-feet per year (ac-ft/yr),or full flow; 3.the source (stream or river,spring,well)and well depth; 4.the priority date and number of days during the year that the water is used; 5.the lattitude/longitude coordinates for the point of diversion and point of use,and the quarter section of the township where this occurs; -5- 6.the legal status (certificate,permit,or pending)of the water right;and 1 'I 7.the appropriator's name. Case files for certificates,permits,and applications pending are stored in the district offices of DNR's Division of Land and Water \ Management. -6~ I I I ~j SEARCH STRATEGY AND DATA INTERPRETATION In response to a request from Acres,DNR's Water Management Section staff searched the computer files and generated a printout reflecting all data that had been coded as of September 10,1981.To facilitate the search,they selected township grids for 17 different segments of the river basin.They sent the computer printout and township list to Acres on September 24 (Brown 1981). As the first step to interpreting the data,the 17 township grids were mapped at scale 1:250,000 and transferred to a 1:1,000,000 map (Figure 1).The map was reviewed with DNR Water Management Section staff.Corrections and additions were made,and the Susitna reservoir township grid was included.No other townships were considered neces- sary for the search at this time (G.Doggett,pers.corom.; P.Janke, pers.corom.; G.Prokosch,pers.corom.). To interpret the types of water appropriations identified on'the com- puter printout,the listing that DNR has developed from the standard industrial code was obtained (S.Mack,pers.corom.).Six of the town- ship grids contained no data:Kashwitna,Sheep Creek,Talkeetna, Tokositna,Happy,and Alexander Creek.Suromary tables were developed for the remaining township grids.Each table displays information on certificates,permits,and applications pending.For each type of water use,as described by the standard industrial code classification,the amount of surface water or groundwater appropriated is expressed in cfs, gpd,or ac-ft/yr.The number of days in the year that the water use is "active"is noted.The total amount of surface water and groundwater that has been appropriated in each township grid is tabulated in either cfs,gpd,or ac-ft/yr (see Table 1).Cubic feet per second and gallons per day express the total amount of water as a flow rate;ac-ft/yr expresses that same amount of water as an annual storage volume. In order to compare total water use by township grid,the three flow rates were converted to a single equivalent flow rate,expressed in both -7- cfs and ac-ft/yr (Table 2).The results were summarized to compare total surface and groundwater use by township grids in equivalent flow rates (Table 3). Finally,a 1:250,000 scale overlay was produced with DNR's geoprocessor, which identified the specific location of each recorded water right along the·mainstem Susitna River corridor.This overlay was placed on the corresponding U.S.Geological Survey (USGS)topographic maps for the purpose of identifying potential areas of concern (Ff.gur-es 2 and 3). Five areas were identified where appropriations existed within the vicinity (less than one mile)of the mainstem Susitna River.Two areas were examined further on a :1:63 ,360 overlay and USGS topographic map (Figure 4). -8- J Ii -I r:l I ,1 I t DISCUSSION Based on a comparison of equivalent cfs and ac-ft/yr (Table 3),the only significant uses of surface water in the Susitna River basin occur in the headwaters of the Kahiltna and Willow Creek township grids.Its principal use is for mining operations on a seasonal basis.Water appropriations are 125 cfs or 37,000 ac-ft!yr in the Kahiltna area and 18.3 cfs or 5,660 ac-ft/yr in the Willow Creek area.Along the mainstem Susitna River,only .153 cfs or 50 ac-ft/yr of surface water has been appropriated for all purposes ..Water appropriations in other areas are even less significant.The following assessment of project effects on existing water rights is focused specifically on the mainstem river corridor.Data on existing water rights for the remaining township grids in the Susitna aiver basin are summarized in the Appendix. The Susitna township grid,which encompasses 30 townships,extends from the proposed impoundment area at Devil Canyon downstream to the estuary. As shown in Table 1,both surface (4,900 gpd)and groundwater (7,600 gpd)appropriations are primarily for single family and multi-family homes.A small amount of water is used year-round for watering livestock.The greatest usage occurs during summer months for irrigating lawns,gardens,and crops.The largest single use of surface water is for placer gold operations. As shown on Figures 2 and 3 and listed on Table 4,there are only five areas where water appropriations are located within one mile of the mainstem Susitna River.There are no surface water diversions recorded that draw water directly from the Susitna River or its adjoining side channels and sloughs. Immediately downstream from the Delta Islands,on the west bank of the Susitna River,a single family dwelling has a certificate for 650 gpd of groundwater from a well of unlisted depth.The certificate includes .5 ac-ft/yr for crop irrigation for three months.About six miles below Talkeetna,and 0.25 miles inland from the west bank of the Susitna River,a single family dwelling has a certificate for 500 gpd of ground- -9- water from a 90-foot deep well.Postproject water surface elevations for the mainstem river below Talkeetna are expected to be approximately three feet higher during winter months and from one half to one and a half feet lower during the summer months (R&M Consultants,Inc.In press)• Such a moderate.range of fluctuation is not expected to adversely affect the groundwater zones being tapped by two small capa- city domestic wells in the Delta Islands and Trapper Creekateas~ In the vicinity of Sherman,at mile 258 of the Alaska Railroad,Sherman Creek and an unnamed stream have been appropriated for two single family dwellings (325 gpd)and lawn and garderi irrigation (50 gpd).The surface water appropriations at Sherman are 50 to 100 feet above the present elevation of the Susitna River and would not be influenced by changes in water surface elevation of the Susitna River. In Talkeetna,groundwater from three shallow (20,27,and 34 f t )wells have been appropriated for a single family dwelling (500 gpd),the grade school (910 gpd),and the fire station (500 gpd).In the vicinity of Chase,between mile'235 and 236 of tll~A:LC3.ska.Rai:I.l:'9~Cld.,_~E;Ye_ral unnamed streams,lakes,and creeks have been appropriated for single family dwellings (L,250 gpd), lawn and garden irrigation (l00 gpd), and crops (1 ac-ft/yr).The appropriations in the vicinity of Talkeetna and Chase were examined on a 1:63,360 overlay and USGS topographic map (Figure 4). --The ----three'shallow ---wells'{20-34£tdepth)recordedin'-TaTlCee'fiia.are ---~.,approximately 1.5~milesdownstream from the-~onfi~en~e of the Chulitna- and Susitna Rivers and 0.13 miles downstream from the confluence of the Talkeetna River.From all visual indications,the Talkeetna River appears to be up gradient and is the principal recharge source for these wells.It appearS that the water surface elevation of the Susitna River could be influencirig-thegroundwater'level by providing the down gradient base elevation for the water table.However,the anticipated maximum decrease in average monthly water surface elevation of the Susitna River near Talkeetna is forecast to be from one to one and a -10- I I 'I ./ half feet (R&M Consultants,Inc.In press).At worst,this might reduce the water surface elevations of the local water table one to one and a half feet. In the vicinity of Chase,all surface water appropriations are from small tributary streams and lakes at an elevation of 450 to 500 ft mean sea level (msl).The Susitna River is approximately 0.25 miles from the nearest appropriation and is at an elevation of approximately 400 ft msl.The anticipated ch~nge in water surface elevation for the mainstem Susitna River near Chase is unlikely to have any affect on surface water diversions from small streams or lakes located 50 to 100 ft above the river on the hillsides. -11- -12- ,I I I i I ! ! i ,.--1 I I i I i I ( J i !

Willow Creek Township Grid (5 townships) On a year-round basis,groundwater is the major source of water for single family dwellings,the library,a campground,and animals,lawns, gardens,and crops (Table 6).Groundwater supplies are used year-round at the Independence Mine (83,120 gpd).The major use of surface water occurs on a seasonal basis for mining operations. Little Willow Creek Township Grid (2 townships) A small amount of surface water and groundwater is utilized for single family dwellings and for watering animals,lawns,and gardens (Table 7). Montana Creek Township Grid (4 townships) Groundwater is the maj or source for single family dwellings,schools, and for watering animals and crops (Table 8). Chulina Township Grid (1 township) A small amount of both surface water and groundwater is used for single family dwellings and for watering animals,lawns,and gardens (Table 9). Susitna Reservoir Township Grid (46 townships) The only appropriation recorded in the area encompassed by the proposed reservoir is the permit held by the Alaska Power Authority for the forty man camp from which field work is conducted in support of the feasi- bility studies.The permit is for 3,000 gpd of lake water (Table 10). Chulitna Township Grid (13 townships) A limited amount of groundwater is appropriated for year-round use,120 gpd for single family dwellings and 2,000 gpd for trailer park camps (Table 11).
