The proposed dike w i l l actually be a reconstruction of a

similar rock cr ib s t ructure which blocked the bypass channel

u n t i l i t was breached about 1952. Bypass channel erosion since

the breaching has caused the formation of an accretion island

j u s t upstream of the powerhouse t a i l r a c e and f i l l i n g of the

t a i l r a c e channel. Four ae r i a l photos are enclosed: photo no. 1

(1951) shows the or iginal diversion dike i n t a c t ; photo no. 2

(1974) shows the dike breached and the accretion island a t high

water; the accretion island i s obvious a t l o w water i n photo no. 3

( 1 9 8 0 ) ; photo no. 4 was taken during powerhouse repair i n 1981.

Tailrace capacity was reestablished during the Applicant's

powerhouse repair project completed i n October, 1981. Diverting

flow from the bypass channel w i l l permit maximum u t i l i z a t i o n of

the generating capacity of t h i s powerhouse and essent ia l ly elimin-

a t e future t a i l r a c e maintenance.

Three a l te rna te designs a re acceptable:

1) Gravelly, s i l t y sand layer bedded on graded rock and

2 ) Gravelly, s i l t y sand layer overlain with f i l t e r fabr ic

3) Nylon-encased concrete armor with riprapped toe.

The design elevation (167 f e e t ) w i l l provide t w o f e e t of

no flow through the powerhouse. The dike w i l l be overtopped only

A 6-8 week construction period i s anticipated.

flow and discharge from the Grand Fa l l s Dam can be regulated t o

some degree. No cofferdamming should be necessary; i n the event

of unusual precipi ta t ion some minor cofferdamming using sandbags

may be necessary.

Suitable material may be salvaged from’ the existing dike and

8. In addition t o International Jo in t Commission approval, the

project w i l l require these Federal, Provincial and State permits,

approvals and leases :

a. A Section 4 0 4 (P.L. 92-500) Permit from the U.S . Army

Corps o f Engineers.

A Stream Alteration Permit from the Maine Department

of Inland Fisheries and Wildlife.

b.

c. A Water Quality Cert i f icat ion (Section 4 0 1 , P.L. 92-500)

from the Maine Department of Environmental Protection.

A lease for use of submerged land from the Maine

Department of Conservation, Bureau of Public Lands.

d.

e. A Navigable Waters Protection Act Permit from the Canadian
